There is no really good reason to have a merge with more than 16
parents, but we have a history of giving our users rope.
Combined with the fact that there was no good reason for that
arbitrary limit in the first place, here is an all-too-easy to fix.

A lot of modules that have nothing to do with git-shell functionality
were linked in, bloating git-shell more than 8 times.
This patch cuts off redundant dependencies by:
1. providing stubs for three functions that make no sense for git-shell;
2. moving quote_path_fully from environment.c to quote.c to make the
later self sufficient;
3. moving make_absolute_path into a new separate file.

Before this patch, something like "git help tutorial" did not work,
people had to use "git help gittutorial" which is not very intuitive.
This patch uses the "is_git_command" function to test early if the
argument passed to "git help" is a git command, and if this is not the
case then we prefix the argument with "git" instead of "git-".
This way, things like "git help tutorial" or "git help glossary" will
work fine.
The little downside of this patch is that the "is_git_command" is a
little bit slow.

I'm working with a perforce repo using git-p4. There are some config
files which I need to change locally according to my environment. I'm
using a 'local' git branch to park these changes. And I want to avoid
accidentally checking them into p4 just by doing "git p4 submit"
mindlessly without realizing which branch I'm actually on.
This patch adds a new git config, 'git-p4.allowSubmit', which is a
whitelist of branch names. "git p4 submit" will only allow submissions
from local branches on the list. Useful for preventing inadvertently
submitting from a strictly local branch.
For backward compatibility, if this config is not set at all,
submissions from all branches are allowed.

Sometimes it is desirable to have non-fast-forward branches in a
shared repository. A typical example of that is the 'pu' branch.
This patch extends the format of allowed-users and allow-groups
files by using the '+' sign at the beginning as the mark that
non-fast-forward pushes are permitted to the branch.

The shell version used to use "mkdir -p" to create the repo
path, but the C version just calls "mkdir". Let's replicate
the old behavior. We have to create the git and worktree
leading dirs separately; while most of the time, the
worktree dir contains the git dir (as .git), the user can
override this using GIT_WORK_TREE.
We can reuse safe_create_leading_directories, but we need to
make a copy of our const buffer to do so. Since
merge-recursive uses the same pattern, we can factor this
out into a global function. This has two other cleanup
advantages for merge-recursive:
1. mkdir_p wasn't a very good name. "mkdir -p foo/bar" actually
creates bar, but this function just creates the leading
directories.
2. mkdir_p took a mode argument, but it was completely
ignored.

We used to mark hooks we ship as samples by making them unexecutable, but
some filesystems cannot tell what is executable and what is not.
This makes it much more explicit. The hooks are suffixed with .sample
(but now are made executable), so enabling it is still one step operation
(instead of "chmod +x $hook", you would do "mv $hook.sample $hook") but
now they won't get accidentally enabled on systems without executable bit.

We should be able to fall back to loose objects or alternative packs when
a pack becomes corrupted. This is especially true when an object exists
in one pack only as a delta but its base object is corrupted. Currently
there is no way to retrieve the former object even if the later is
available in another pack or loose.
This patch allows for a delta to be resolved (with a performance cost)
using a base object from a source other than the pack where that delta
is located. Same thing for non-delta objects: rather than failing
outright, a search is made in other packs or used loose when the
currently active pack has it but corrupted.
Of course git will become extremely noisy with error messages when that
happens. However, if the operation succeeds nevertheless, a simple
'git repack -a -f -d' will "fix" the corrupted repository given that all
corrupted objects have a good duplicate somewhere in the object store,
possibly manually copied from another source.

Suppose someone fetches git-svn-ified commits from another repo and then
attempts to use 'git-svn init --rewrite-root=foo bar'. Using git svn rebase
after that will fail badly:
* For each commit tried by working_head_info, rebuild is called indirectly.
* rebuild will iterate over all commits and skip all of them because the
URL does not match. Because of that no rev_map file is generated at all.
* Thus, rebuild will run once for every commit. This takes ages.
* In the end there still isn't any rev_map file and thus working_head_info
fails.
Addressing this behaviour fixes an apparently not too uncommon problem with
providing git-svn mirrors of Subversion repositories. Some repositories are
accessed using different URLs depending on whether the user has push
privileges or not. In the latter case, an anonymous URL is often used that
differs from the push URL. Providing a mirror that is usable in both cases
becomes a lot more possible with this change.

So I was looking at the disgusting size of the git binary, and even with
the debugging removed, and using -Os instead of -O2, the size of the text
section was pretty high. In this day and age I guess almost a megabyte of
text isn't really all that surprising, but it still doesn't exactly make
me think "lean and mean".
With -Os, a surprising amount of text space is wasted on inline functions
that end up just being replicated multiple times, and where performance
really isn't a valid reason to inline them. In particular, the trivial
wrapper functions like "xmalloc()" are used _everywhere_, and making them
inline just duplicates the text (and the string we use to 'die()' on
failure) unnecessarily.
So this just moves them into a "wrapper.c" file, getting rid of a tiny bit
of unnecessary bloat. The following numbers are both with "CFLAGS=-Os":
Before:
[torvalds@woody git]$ size git
text data bss dec hex filename
700460 15160 292184 1007804 f60bc git
After:
[torvalds@woody git]$ size git
text data bss dec hex filename
670540 15160 292184 977884 eebdc git
so it saves almost 30k of text-space (it actually saves more than that
with the default -O2, but I don't think that's necessarily a very relevant
number from a "try to shrink git" standpoint).
It might conceivably have a performance impact, but none of this should be
_that_ performance critical. The real cost is not generally in the wrapper
anyway, but in the code it wraps (ie the cost of "xread()" is all in the
read itself, not in the trivial wrapping of it).
