revert: plug memory leak in "cherry-pick root commit" codepath
The empty tree passed as common ancestor to merge_trees() when
cherry-picking a parentless commit is allocated on the heap and never
freed. Leaking such a small one-time allocation is not a very big
problem, but now that "git cherry-pick" can cherry-pick multiple
commits it can start to add up.
Avoid the leak by storing the fake tree exactly once in the BSS
section (i.e., use a static). While at it, let's add a test to make
sure cherry-picking multiple parentless commits continues to work.

The following should be possible but does not work:
git cherry-pick -2 master
because "git rev-list --no-walk -2 master" only outputs
one commit as "--no-walk" seems to take over "-2".
And there is currently no way to continue cherry-picking or
reverting if there is a problem with one commit. It's also
not possible to abort the whole process. Some future work
should provide the --continue and --abort options to do
just that.

This is needed because the following commits will make it
possible to cherry-pick many commits instead of just one.
So it will be possible to pass for example ranges of commits
to "git cherry-pick" and this means that it will not be
possible to use the arguments passed to "git cherry-pick" in
the help message.
The help message will have to use the sha1 of the currently
processed commit.

Fix checkout of large files to network shares on Windows XP
Bigger writes to network drives on Windows XP fail. Cap them at 31MB to
allow them to succeed. Callers need to be prepared for write() calls
that do less work than requested anyway.
On local drives, write() calls are translated to WriteFile() calls with
a cap of 64KB on Windows XP and 256KB on Vista. Thus a cap of 31MB won't
affect the number of WriteFile() calls which do the actual work. There's
still room for some other version of Windows to use a chunk size of 1MB
without increasing the number of system calls.

start_command: close cmd->err descriptor when fork/spawn fails
Fix the problem where the cmd->err passed into start_command wasn't
being properly closed when certain types of errors occurr. (Compare
the affected code with the clean shutdown code later in the function.)
On Windows, this problem would be triggered if mingw_spawnvpe()
failed, which would happen if the command to be executed was malformed
(e.g. a text file that didn't start with a #! line). If cmd->err was
a pipe, the failure to close it could result in a hang while the other
side was waiting (forever) for either input or pipe close, e.g. while
trying to shove the output into the side band. On msysGit, this
problem was causing a hang in t5516-fetch-push.
[J6t: With a slight adjustment of the test case, the hang is also
observed on Linux.]

if we have a special case for size equal to zero, it is better to make it

Restrict the tags used to generate the version string to those that

code repository, which may break certain machinery (eg. Makefile, gitk).

If we know we are creating a bare repository, we use setenv
to set the GIT_DIR directory to the current directory
(either where we already were, or one we created and chdir'd
into with "git init --bare <dir>").
However, with "git --bare init <dir>" (note the --bare as a
git wrapper option), the setup code actually sets GIT_DIR
for us, but it uses the wrong, original cwd when a directory
is given. Because our setenv does not use the overwrite
flag, it is ignored.
We need to set the overwrite flag, but only when we are
given a directory on the command line. That still allows:
GIT_DIR=foo.git git init --bare
to work. The behavior is changed for:
GIT_DIR=foo.git git init --bare bar.git
which used to create the repository in foo.git, but now will
use bar.git. This is more sane, as command line options
should generally override the environment.
Noticed by Oliver Hoffmann.

When cherry-picking, usually the new and old commit encodings are both
UTF-8. Most old iconv implementations do not support this trivial
conversion, so on old platforms, out->message remains NULL, and later
attempts to read it segfault.
Fix this by noticing the input and output encodings match and skipping
the iconv step, like the other reencode_string() call sites already do.
Also stop segfaulting on other iconv failures: if iconv fails for some
other reason, the best we can do is to pass the old message through.
This fixes a regression introduced in v1.7.1-rc0~15^2~2 (revert:
clarify label on conflict hunks, 2010-03-20).

Make diffcore_std only can run once before a diff_flush
When file renames/copies detection is turned on, the
second diffcore_std will degrade a 'C' pair to a 'R' pair.
And this may happen when we run 'git log --follow' with
hard copies finding. That is, the try_to_follow_renames()
will run diffcore_std to find the copies, and then
'git log' will issue another diffcore_std, which will reduce
'src->rename_used' and recognize this copy as a rename.
This is not what we want.
So, I think we really don't need to run diffcore_std more
than one time.
