A ton of Git commands simply do not read (or at least parse) the core.*
settings. This is not good, as Git for Windows relies on the
core.longPaths setting to be read quite early on.
So let's just make sure that all commands read the config and give
platform_core_config() a chance.
This patch teaches tons of Git commands to respect the config setting
`core.longPaths = true`, including `pack-refs`, thereby fixing

On Mac's HFS where git sets core.precomposeUnicode to true automatically
by git init/clone, when a user creates a simple unicode refname (in NFC
format) such as españa:
$ git branch españa
different commands would display the branch name differently. For
example, git branch, git log --decorate, and git fast-export all used
65 73 70 61 c3 b1 61 (or "espa\xc3\xb1a")
(NFC form) while show-ref would use
65 73 70 61 6e cc 83 61 (or "espan\xcc\x83a")
(NFD form). A stress test for git filter-repo was tripped up by this
inconsistency, though digging in I found that the problems could
compound; for example, if the user ran
$ git pack-refs --all
and then tried to check out the branch, they would be met with:
$ git checkout españa
error: pathspec 'españa' did not match any file(s) known to git
$ git checkout españa --
fatal: invalid reference: españa
$ git branch
españa
* master
Note that the user could run the `git branch` command first and copy and
paste the `españa` portion of the output and still see the same two
errors. Also, if the user added --no-prune to the pack-refs command,
then they would see three branches: master, españa, and españa (those
last two are NFC vs. NFD forms, even if they render the same).
Further, if the user had the `españa` branch checked out before
running `git pack-refs --all`, the user would be greeted with (note
that I'm trimming trailing output with an ellipsis):
$ git rev-parse HEAD
fatal: ambiguous argument 'HEAD': unknown revision or path...
$ git status
On branch españa
No commits yet...
Or worse, if the user didn't check this stuff first, running `git
commit` will create a new commit with all changes of all of history
being squashed into it.
In addition to pack-refs, one could also get into this state with
upload-pack or anything that calls either pack-refs or upload-pack (e.g.
gc or clone).
Add code in a few places (pack-refs, show-ref, upload-pack) to check and
honor the setting of core.precomposeUnicode to avoid these bugs.

Add a repository argument to allow the get_main_ref_store caller
to be more specific about which repository to handle. This is a small
mechanical change; it doesn't change the implementation to handle
repositories other than the_repository yet.
As with the previous commits, use a macro to catch callers passing a
repository other than the_repository at compile time.

This patch puts the usage info strings that were not already in docopt-
like format into docopt-like format, which will be a litle easier for
end users and a lot easier for translators. Changes include:
- Placing angle brackets around fill-in-the-blank parameters
- Putting dashes in multiword parameter names
- Adding spaces to [-f|--foobar] to make [-f | --foobar]
- Replacing <foobar>* with [<foobar>...]

pack-refs.c doesn't contain much code, and the code it does contain is
closely related to reference handling. Moreover, there is some
duplication between pack_refs() and repack_without_ref(). Therefore,
merge pack-refs.c into refs.c and pack-refs.h into refs.h.
The code duplication will be addressed in future commits.

This shrinks the top-level directory a bit, and makes it much more
pleasant to use auto-completion on the thing. Instead of
[torvalds@nehalem git]$ em buil<tab>
Display all 180 possibilities? (y or n)
[torvalds@nehalem git]$ em builtin-sh
builtin-shortlog.c builtin-show-branch.c builtin-show-ref.c
builtin-shortlog.o builtin-show-branch.o builtin-show-ref.o
[torvalds@nehalem git]$ em builtin-shor<tab>
builtin-shortlog.c builtin-shortlog.o
[torvalds@nehalem git]$ em builtin-shortlog.c
you get
[torvalds@nehalem git]$ em buil<tab> [type]
builtin/ builtin.h
[torvalds@nehalem git]$ em builtin [auto-completes to]
[torvalds@nehalem git]$ em builtin/sh<tab> [type]
shortlog.c shortlog.o show-branch.c show-branch.o show-ref.c show-ref.o
[torvalds@nehalem git]$ em builtin/sho [auto-completes to]
[torvalds@nehalem git]$ em builtin/shor<tab> [type]
shortlog.c shortlog.o
[torvalds@nehalem git]$ em builtin/shortlog.c
which doesn't seem all that different, but not having that annoying
break in "Display all 180 possibilities?" is quite a relief.
NOTE! If you do this in a clean tree (no object files etc), or using an
editor that has auto-completion rules that ignores '*.o' files, you
won't see that annoying 'Display all 180 possibilities?' message - it
will just show the choices instead. I think bash has some cut-off
around 100 choices or something.
So the reason I see this is that I'm using an odd editory, and thus
don't have the rules to cut down on auto-completion. But you can
simulate that by using 'ls' instead, or something similar.
