The new command 'git merge' takes the current head and one or more
remote heads, with the commit log message for the automated case.
If the heads being merged are simple fast-forwards, it acts the
same way as the current 'git resolve'. Otherwise, it tries
different merge strategies and takes the result from the one that
succeeded auto-merging, if there is any.
If no merge strategy succeeds auto-merging, their results are
evaluated for number of paths needed for hand resolving, and the
one with the least number of such paths is left in the working
tree. The user is asked to resolve them by hand and make a
commit manually.
The calling convention from the 'git merge' driver to merge
strategy programs is very simple:
- A strategy program is to be called 'git-merge-<strategy>'.
- They take input of this form:
<common1> <common2> ... '--' <head> <remote1> <remote2>...
That is, one or more the common ancestors, double dash, the
current head, and one or more remote heads being merged into
the current branch.
- Before a strategy program is called, the working tree is
matched to the current <head>.
- The strategy program exits with status code 0 when it
successfully auto-merges the given heads. It should do
update-cache for all the merged paths when it does so -- the
index file will be used to record the merge result as a
commit by the driver.
- The strategy program exits with status code 1 when it leaves
conflicts behind. It should do update-cache for all the
merged paths that it successfully auto-merged, and leave the
cache entry in the index file as the same as <head> for paths
it could not auto-merge, and leave its best-effort result
with conflict markers in the working tree when it does so.
- The strategy program exists with status code other than 0 or
1 if it does not handle the given merge at all.
As examples, this commit comes with merge strategies based on
'git resolve' and 'git octopus'.

This will help us detect if real-world example merges have multiple
merge-base candidates and one of them matches one head while another
matches the other head.

The 'git bisect' command was very unforgiving in that once you made a
mistake telling it good/bad it was very hard to take it back. Keep a
log of what you told it in an earlier session, so that it can be
replayed after removing everything after what you botched last time.

When (A,B) ==> (B,C) rename-copy was detected, we incorrectly said
that C was created by copying B. This is because we only check if the
path of rename/copy source still exists in the resulting tree to see
if the file is renamed out of existence. In this case, the new B is
created by copying or renaming A, so the original B is lost and we
should say C is a rename of B not a copy of B.

We now keep track of the patches merged in each branch since they have
diverged, using the records that the Arch "logs" provide. Merge parents
for a commit are defined if we are merging a series of patches that starts
from the mergebase.
If patches from a related branch are merged out-of-order, we keep track of
how much has been merged sequentially -- the tip of that sequential merge
is our new parent from that branch.
This mechanism works very well for branches that merge in dovetail and/or
flying fish patterns, probably less well for others.

The --list option is what 'git branch' without parameter should
have been; it shows the one-line commit message for each branch
name. The --independent option is used to filter out commits
that can be reachable from other commits, to make detection of
fast forward condition in multi-head merge easier.

Remove duplicate git-send-email-perl target in Makefile.
When WITH_SEND_EMAIL was defined, as in the Debian 'deb' target,
git-send-email-perl was added twice to SCRIPT_PERL, leading to a
duplicate definition in the Makefile. Creating a ".deb" then failed.

Earlier we renamed git-foo.sh to git-foo while installing, which
was mostly done by inertia than anything else. This however
made writing tests to use scripts harder.
This patch builds the scripts the same way as we build binaries
from their sources. As a side effect, you can now specify
non-standard paths you have your Perl binary is in when running
the make.

git-daemon using inetd. does not work properly. inetd routes stderr onto the
network line just like stdout, which was apparently not expected to be so.
As the result of this, the stream is closed by the receiver, because some
"Packing %d objects\n" originating from pack_objects is first reported over
the line instead of the expected pack_header, and so the SIGNATURE test
fails. Here is a workaround.

As promised, this is the "big tool rename" patch. The primary differences
since 0.99.6 are:
(1) git-*-script are no more. The commands installed do not
have any such suffix so users do not have to remember if
something is implemented as a shell script or not.
(2) Many command names with 'cache' in them are renamed with
'index' if that is what they mean.
There are backward compatibility symblic links so that you and
Porcelains can keep using the old names, but the backward
compatibility support is expected to be removed in the near
future.
