Teach git to read the system and global config files for
default Trace2 settings. This allows system-wide Trace2 settings to
be installed and inherited to make it easier to manage a collection of
systems.
The original GIT_TR2* environment variables are loaded afterwards and
can be used to override the system settings.
Only the system and global config files are used. Repo and worktree
local config files are ignored. Likewise, the "-c" command line
arguments are also ignored. These limits are for performance reasons.
(1) For users not using Trace2, there should be minimal overhead to
detect that Trace2 is not enabled. In particular, Trace2 should not
allocate lots of otherwise unused data strucutres.
(2) For accurate performance measurements, Trace2 should be initialized
as early in the git process as possible, and before most of the normal
git process initialization (which involves discovering the .git directory
and reading a hierarchy of config files).

Created an even lighter version of read_early_config() that
only looks at system and global config settings. It omits
repo-local, worktree-local, and command-line settings.

Teach Git to resolve the executable directory before initializing
Trace2. This allows the system configuration directory to be
discovered earlier (because it is sometimes relative to the prefix
or runtime-prefix).
This will be used by the next commit to allow trace2 settings to
be loaded from the system config.

Initialize opts structure in repo_read_config().
This change fixes a crash in later commit after a new field is added
to the structure.
In commit 3b256228a66f8587661481ef3e08259864f3ba2a, repo_read_config()
was added. It only initializes 3 fields in the opts structure. It is
passed to config_with_options() and then to do_git_config_sequence().
However, do_git_config_sequence() drops the opts on the floor and calls
git_config_from_file() rather than git_config_from_file_with_options(),
so that may be why this hasn't been a problem in the past.

A recent update broke "is this object available to us?" check for
well-known objects like an empty tree (which should yield "yes",
even when there is no on-disk object for an empty tree), which has
been corrected.

On platforms where "git fetch" is killed with SIGPIPE (e.g. OSX),
the upload-pack that runs on the other end that hangs up after
detecting an error could cause "git fetch" to die with a signal,
which led to a flakey test. "git fetch" now ignores SIGPIPE during
the network portion of its operation (this is not a problem as we
check the return status from our write(2)s).
* jk/no-sigpipe-during-network-transport:
fetch: ignore SIGPIPE during network operation
fetch: avoid calling write_or_die()

"git fsck --connectivity-only" omits computation necessary to sift
the objects that are not reachable from any of the refs into
unreachable and dangling. This is now enabled when dangling
objects are requested (which is done by default, but can be

The final report from "git bisect" used to show the suspected
culprit using a raw "diff-tree", with which there is no output for
a merge commit. This has been updated to use a more modern and

The Makefile uses 'find' utility to enumerate all the *.h header
files, which is expensive on platforms with slow filesystems; it

Recently the Git for Windows project started the upgrade process to
a MSYS2 runtime version based on Cygwin v3.x.
This has the very notable consequence that `$(uname -r)` no longer
reports a version starting with "2", but a version with "3".
That breaks our build, as df5218b4c30b (config.mak.uname: support MSys2,
2016-01-13) simply did not expect the version reported by `uname -r` to
depend on the underlying Cygwin version: it expected the reported
version to match the "2" in "MSYS2".
So let's invert that test case to test for *anything else* than a
version starting with "1" (for MSys). That should safeguard us for the
future, even if Cygwin ends up releasing versionsl like 314.272.65536.

Rather than parse options manually, which is both difficult to
read and error prone, parse options supplied to commit-tree
using the parse-options api.
It was discovered that the --no-gpg-sign option was documented
but not implemented in commit 70ddbd7767 (commit-tree: add missing
--gpg-sign flag, 2019-01-19), and the existing implementation
would attempt to translate the option as a tree oid. It was also
suggested earlier in commit 55ca3f99ae (commit-tree: add and document
--no-gpg-sign, 2013-12-13) that commit-tree should be migrated to
utilize the parse-options api, which could help prevent mistakes
like this in the future. Hence this change.
Also update the documentation to better describe that mixing
`-m` and `-F` options will correctly compose commit log messages in the
order in which the options are given.
In the process, mark various strings for translation.

Even though the newer "--type=color" option to "git config" is meant
to be upward compatible with the traditional "--get-color" option,
unlike the latter, its output is not an incomplete line that lack
the LF at the end. That makes it consistent with output of other
types like "git config --type=bool".
Document it, as it sometimes surprises unsuspecting users.
