replace direct calls to unlink(2) with unlink_or_warn
This helps to notice when something's going wrong, especially on
systems which lock open files.
I used the following criteria when selecting the code for replacement:
- it was already printing a warning for the unlink failures
- it is in a function which already printing something or is
called from such a function
- it is in a static function, returning void and the function is only
called from a builtin main function (cmd_)
- it is in a function which handles emergency exit (signal handlers)
- it is in a function which is obvously cleaning up the lockfiles

Introduce an unlink(2) wrapper which gives warning if unlink failed
This seem to be a very common pattern in the current code.
The function prints a generic removal failure message, the file name
which failed and readable errno presentation. The function preserves
errno and always returns the value unlink(2) returned, but prints
no message for ENOENT, as it was the most often filtered out in the
code calling unlink. Besides, removing a file is anyway the purpose of
calling unlink.

On OS X (and maybe other unices), getaddrinfo(3) returns NULL
in the ai_canonname field if it's called with an IP address for
the hostname. We'll now use the IP address for the hostname if
ai_canonname was NULL, this also matches the behaviour on Linux.
merge-recursive: do not die on a conflicting submodule
We cannot represent the 3-way conflicted state in the work tree
for these entries, but it is normal not to have commit objects
for them in our repository. Just update the index and the life
will be good.
The combine diff logic knew only about blobs (and their checked-out form
in the work tree, either regular files or symlinks), and barfed when fed
submodules. This "externalizes" gitlinks in the same way as the normal
patch generation codepath does (i.e. "Subproject commit Xxx\n") to fix the
issue.
On platforms with $X, make removes any leftover scripts 'a' from
earlier builds if a new binary 'a.exe' is now built. However, on
cygwin 1.7.0, 'git' and 'git.exe' now consistently name the same file.
Test for file equality before attempting a remove, in order to avoid
nuking just-built binaries.
This repeats commit 0d768f7 for the installation destdir.

When the user has defined NO_PERL, we want to skip building
gitweb entirely. However, the conditional to add
gitweb/gitweb.cgi to OTHER_PROGRAMS was evaluated before we
actually parsed the user's config.mak. This meant that "make
NO_PERL=NoThanks" worked fine, but putting "NO_PERL=NoThanks"
into your config.mak broke the build (it wanted gitweb.cgi
to satisfy "all", but the rule to build it was conditionally
ignored, so it complained).

Trying to be lazy and comparing files with fake-editor.sh to avoid
having to provide another example text does not work well: the blob
name changes when SHELL_PATH changes, and so does the 'index' line
in the diff.
Therefore provide a second example text.

prune-packed: advanced progress even for non-existing fan-out directories
A progress indicator is used to count through the 256 object fan-out
directories while unused object files are removed. (However, it becomes
visible only if this process takes long enough.)
Previously, display_progress() was only called if object files were
actually removed. But if directories towards the end (fd/, fe/, ff/) did
not exist, this could leave a strange line
Removing duplicate objects: 99% (255/256), done.

Add an option not to use link(src, dest) && unlink(src) when that is unreliable
It seems that accessing NTFS partitions with ufsd (at least on my EeePC)
has an unnerving bug: if you link() a file and unlink() it right away,
the target of the link() will have the correct size, but consist of NULs.
It seems as if the calls are simply not serialized correctly, as single-stepping
through the function move_temp_to_file() works flawlessly.
As ufsd is "Commertial software" (sic!), I cannot fix it, and have to work
around it in Git.
At the same time, it seems that this fixes msysGit issues 222 and 229 to
assume that Windows cannot handle link() && unlink().

inet_ntop is not protocol independent.
getnameinfo(3) is part of POSIX and is available when getaddrinfo(3) is.
This code is only compiled when NO_IPV6 isn't defined.
The old method was buggy anyway, not every ipv6 address was converted
properly because the buffer (addr) was too small.

t9001: use older Getopt::Long boolean prefix '--no' rather than '--no-'
The '--no-thread' option is a Getopt::Long boolean option. The '--no-'
prefix (as in --no-thread) for boolean options is not supported in
Getopt::Long version 2.32 which was released with Perl 5.8.0. This version
only supports '--no' as in '--nothread'. More recent versions of
Getopt::Long, such as version 2.34, support either prefix. So use the older
form in the tests.

progress bar: round to the nearest instead of truncating down
Often the throughput output is requested when the data read so far is
one smaller than multiple of 1024; because 1023/1024 is ~0.999, it often
shows up as 0.99 because the code currently truncates.
Now we only prune out a commit if it has exactly one remaining parent and
that parent's tree is identical to ours.
But I also changed the test to create the initial "-s ours" merge in one
step instead of two, and that merge can be eliminated since one of its
parents doesn't affect the subdir at all, and is thus deleted.
Now we cut out a commit if any of its parents had the same tree; just use
that parent in its place. This makes the history look nice, but I don't
think it's quite right...
The idea is to join the new split branch back into this one, so future
splits can append themselves to the old split branch. We mark the split
branch's history in our merge commit, so we can pull it back out later.
remote.c: do not trigger remote.<name>.<var> codepath for two-level names
If the config file contains a section like this:
[remote]
default = foo
(it should be '[remotes]') then commands like
git status
git checkout
git branch -v
fail even though they are not obviously related to remotes. (These
commands write "ahead, behind" information and, therefore, access the
per-remote information).
Unknown configuration keys should be ignored, not trigger errors.

If for some reason the config file contains a key without a subkey like
[man]
foo = bar
then even a plain
git help
produces an error message. With this patch such an entry is ignored.
Additionally, the warning about unknown sub-keys is removed. It could
become annoying if new sub-keys are introduced in the future, and then
the configuration is read by an old version of git that does not know
about it.

'git submodule update --rebase' rebases your local branch on top of what
would have been checked out to a detached HEAD otherwise.
In some cases, detaching the HEAD when updating a submodule complicates
the workflow to commit to this submodule (checkout master, rebase, then
commit). For submodules that require frequent updates but infrequent
(if any) commits, a rebase can be executed directly by the git-submodule
command, ensuring that the submodules stay on their respective branches.
