When attempting to read the XDG-style $HOME/.config/git/config and

RFC 2047 requires more characters to be encoded than it is currently done.
Especially, RFC 2047 distinguishes between allowed remaining characters
in encoded words in addresses (From, To, etc.) and other headers, such
as Subject.
Make add_rfc2047() and is_rfc2047_special() location dependent and include
all non-allowed characters to hopefully be RFC 2047 conformant.
This especially fixes a problem, where RFC 822 specials (e. g. ".") were
left unencoded in addresses, which was solved with a non-standard-conforming
workaround in the past (which is going to be removed in a follow-up patch).

Git reads multiple configuration files: settings come first from the
system config file (typically /etc/gitconfig), then the xdg config
file (typically ~/.config/git/config), then the user's dotfile
(~/.gitconfig), then the repository configuration (.git/config).
Git has always used access(2) to decide whether to use each file; as
an unfortunate side effect, that means that if one of these files is
unreadable (e.g., EPERM or EIO), git skips it. So if I use
~/.gitconfig to override some settings but make a mistake and give it
the wrong permissions then I am subject to the settings the sysadmin
chose for /etc/gitconfig.
Better to error out and ask the user to correct the problem.
This only affects the user and xdg config files, since the user
presumably has enough access to fix their permissions. If the system
config file is unreadable, the best we can do is to warn about it so
the user knows to notify someone and get on with work in the meantime.

The access_or_warn() function is used to check for optional
configuration files like .gitconfig and .gitignore and warn when they
are not accessible due to a configuration issue (e.g., bad
permissions). It is not supposed to complain when a file is simply
missing.
Noticed on a system where ~/.config/git was a file --- when the new
XDG_CONFIG_HOME support looks for ~/.config/git/config it should
ignore ~/.config/git instead of printing irritating warnings:
$ git status -s
warning: unable to access '/home/jrn/.config/git/config': Not a directory
warning: unable to access '/home/jrn/.config/git/config': Not a directory
warning: unable to access '/home/jrn/.config/git/config': Not a directory

Pieces to support compilation on __TANDEM.
* js/compat-itimer:
Add a no-op setitimer() wrapper

The current code uses setitimer() only for reducing perceived
latency. On platforms that lack setitimer() (e.g. HP NonStop),
allow builders to say "make NO_SETITIMER=YesPlease" to use a no-op
substitute, as doing so would not affect correctness.
HP NonStop does provide struct itimerval, but other platforms may
not, so this is taken care of in this commit too, by setting
NO_STRUCT_ITIMERVAL.

The previous series introduced warnings to multiple places, but it
could become tiring to see the warning on the same path over and
over again during a single run of Git. Making just one function
responsible for issuing this warning, we could later choose to keep
track of which paths we issued a warning (it would involve a hash
table of paths after running them through real_path() or something)
in order to reduce noise.
Right now we do not know if the noise reduction is necessary, but it
still would be a good code reduction/sharing anyway.

Before reading a config file, we check "!access(path, R_OK)"
to make sure that the file exists and is readable. If it's
not, then we silently ignore it.
For the case of ENOENT, this is fine, as the presence of the
file is optional. For other cases, though, it may indicate a
configuration error (e.g., not having permissions to read
the file). Let's print a warning in these cases to let the
user know.

Mac OS X mangles file names containing unicode on file systems HFS+,
VFAT or SAMBA. When a file using unicode code points outside ASCII
is created on a HFS+ drive, the file name is converted into
decomposed unicode and written to disk. No conversion is done if
the file name is already decomposed unicode.
Calling open("\xc3\x84", ...) with a precomposed "Ä" yields the same
result as open("\x41\xcc\x88",...) with a decomposed "Ä".
As a consequence, readdir() returns the file names in decomposed
unicode, even if the user expects precomposed unicode. Unlike on
HFS+, Mac OS X stores files on a VFAT drive (e.g. an USB drive) in
precomposed unicode, but readdir() still returns file names in
decomposed unicode. When a git repository is stored on a network
share using SAMBA, file names are send over the wire and written to
disk on the remote system in precomposed unicode, but Mac OS X
readdir() returns decomposed unicode to be compatible with its
behaviour on HFS+ and VFAT.
The unicode decomposition causes many problems:
- The names "git add" and other commands get from the end user may
often be precomposed form (the decomposed form is not easily input
from the keyboard), but when the commands read from the filesystem
to see what it is going to update the index with already is on the
filesystem, readdir() will give decomposed form, which is different.
- Similarly "git log", "git mv" and all other commands that need to
compare pathnames found on the command line (often but not always
precomposed form; a command line input resulting from globbing may
be in decomposed) with pathnames found in the tree objects (should
be precomposed form to be compatible with other systems and for
consistency in general).
- The same for names stored in the index, which should be
precomposed, that may need to be compared with the names read from
readdir().
NFS mounted from Linux is fully transparent and does not suffer from
the above.
As Mac OS X treats precomposed and decomposed file names as equal,
we can
- wrap readdir() on Mac OS X to return the precomposed form, and
- normalize decomposed form given from the command line also to the
precomposed form,
to ensure that all pathnames used in Git are always in the
precomposed form. This behaviour can be requested by setting
"core.precomposedunicode" configuration variable to true.
The code in compat/precomposed_utf8.c implements basically 4 new
functions: precomposed_utf8_opendir(), precomposed_utf8_readdir(),
precomposed_utf8_closedir() and precompose_argv(). The first three
are to wrap opendir(3), readdir(3), and closedir(3) functions.
The argv[] conversion allows to use the TAB filename completion done
by the shell on command line. It tolerates other tools which use
readdir() to feed decomposed file names into git.
When creating a new git repository with "git init" or "git clone",
"core.precomposedunicode" will be set "false".
The user needs to activate this feature manually. She typically
sets core.precomposedunicode to "true" on HFS and VFAT, or file
systems mounted via SAMBA.

When getpwuid fails, we give a cute but cryptic message.
While it makes sense if you know that getpwuid or identity
functions are being called, this code is triggered behind
the scenes by quite a few git commands these days (e.g.,
receive-pack on a remote server might use it for a reflog;
the current message is hard to distinguish from an
authentication error). Let's switch to something that gives
a little more context.
While we're at it, we can factor out all of the
cut-and-pastes of the "you don't exist" message into a
wrapper function. Rather than provide xgetpwuid, let's make
it even more specific to just getting the passwd entry for
the current uid. That's the only way we use getpwuid anyway,
and it lets us make an even more specific error message.
The current message also fails to mention errno. While the
usual cause for getpwuid failing is that the user does not
exist, mentioning errno makes it easier to diagnose these
problems. Note that POSIX specifies that errno remain
untouched if the passwd entry does not exist (but will be
set on actual errors), whereas some systems will return
ENOENT or similar for a missing entry. We handle both cases
in our wrapper.

* jc/pickaxe-ignore-case:
ctype.c: Fix a sparse warning
pickaxe: allow -i to search in patch case-insensitively

In particular, sparse complains as follows:
SP ctype.c
ctype.c:30:12: warning: symbol 'tolower_trans_tbl' was not declared.\
Should it be static?
An appropriate extern declaration for the 'tolower_trans_tbl' symbol
is included in the "cache.h" header file. In order to suppress the
warning, therefore, we could replace the "git-compat-util.h" header
inclusion with "cache.h", since "cache.h" includes "git-compat-util.h"
in turn. Here, however, we choose to move the extern declaration for
'tolower_trans_tbl' into "git-compat-util.h", alongside the other
extern declaration from ctype.c for 'sane_ctype'.

If you access repositories over smart-http using http
authentication, then it can be annoying to have git ask you
for your password repeatedly. We cache credentials in
memory, of course, but git is composed of many small
programs. Having to input your password for each one can be
frustrating.
This patch introduces a credential helper that will cache
passwords in memory for a short period of time.

Do not include header files when compiling with MSVC that do not

A direct consequence is that git can be compiled again with MSVC

#ifndef mingw32 is the only one that is strange
... everything for systems that is not strange ...
#else
... include mingw specific tweaks ...
#endif
#ifdef msvc is also strange
... include msvc specific tweaks ...

it turns things around and says what it wants to achieve in a more direct
way, i.e.
#if mingw32
#include "compat/mingw.h"

The earlier design was to take whatever non-alnum that the short format
parser happens to support, leaving the rest as part of the pattern, so a
version of git that knows '*' magic and a version that does not would have
behaved differently when given ":*Makefile". The former would have
applied the '*' magic to the pattern "Makefile", while the latter would
used no magic to the pattern "*Makefile".
Instead, just reserve all non-alnum ASCII letters that are neither glob
nor regexp special as potential magic signature, and when we see a magic
that is not supported, die with an error message, just like the longhand
codepath does.
With this, ":%#!*Makefile" will always mean "%#!" magic applied to the
pattern "*Makefile", no matter what version of git is used (it is a
different matter if the version of git supports all of these three magic
matching rules).
Also make ':' without anything else to mean "there is no pathspec". This
would allow differences between "git log" and "git log ." run from the top
level of the working tree (the latter simplifies no-op commits away from
the history) to be expressed from a subdirectory by saying "git log :".

Starting with commit c793430 (Limit file descriptors used by packs,
2011-02-28), git uses getrlimit to tell how many file descriptors it
can use. Unfortunately it does not include the header declaring that
function, resulting in compilation errors:
sha1_file.c: In function 'open_packed_git_1':
sha1_file.c:718: error: storage size of 'lim' isn't known
sha1_file.c:721: warning: implicit declaration of function 'getrlimit'
sha1_file.c:721: error: 'RLIMIT_NOFILE' undeclared (first use in this function)
sha1_file.c:718: warning: unused variable 'lim'
The standard header to include for this is <sys/resource.h> (which on
some systems itself requires declarations from <sys/types.h> or
<sys/time.h>). Probably the problem was missed until now because in
current glibc sys/resource.h happens to be included by sys/wait.h.
MinGW does not provide sys/resource.h (and compat/mingw takes care of
providing getrlimit some other way), so add the missing #include to
the "#ifndef __MINGW32__" block in git-compat-util.h.

Since an obvious implementation of va_list is to make it a pointer
into the stack frame, implementing va_copy as "dst = src" will work on
many systems. Platforms that use something different (e.g., a size-1
array of structs, to be assigned with *(dst) = *(src)) will need some
other compatibility macro, though.
Luckily, as the glibc manual hints, such systems tend to provide the
__va_copy macro (introduced in GCC in March, 1997). By using that if
it is available, we can cover our bases pretty well.

va_copy is C99. We have avoided using va_copy many times in the past,
which has led to a bunch of cut-and-paste. From everything I found

The idiom (a + b < a) works fine for detecting that an unsigned
integer has overflowed, but a more explicit
unsigned_add_overflows(a, b)
might be easier to read.
Define such a macro, expanding roughly to ((a) < UINT_MAX - (b)).
Because the expansion uses each argument only once outside of sizeof()
expressions, it is safe to use with arguments that have side effects.
