Jeff King 0ea68e4296 get_repo_path: refactor path-allocation
The get_repo_path function calls mkpath() and then does some
non-trivial operations on it, like calling
is_git_directory() and read_gitfile(). These are actually
OK (they do not use more pathname static buffers
themselves), but it takes a fair bit of work to verify.

Let's use our own strbuf to store the path, and we can
simply reuse it for each iteration of the loop (we can even
avoid rewriting the beginning part, since we are trying a
series of suffixes).

To make the strbuf cleanup easier, we split out a thin
wrapper. As a bonus, this wrapper can factor out the
canonicalization that happens in all of the early-return
code paths.

	Git - the stupid content tracker

////////////////////////////////////////////////////////////////

"git" can mean anything, depending on your mood.

 - random three-letter combination that is pronounceable, and not
   actually used by any common UNIX command.  The fact that it is a
   mispronunciation of "get" may or may not be relevant.
 - stupid. contemptible and despicable. simple. Take your pick from the
   dictionary of slang.
 - "global information tracker": you're in a good mood, and it actually
   works for you. Angels sing, and a light suddenly fills the room.
 - "goddamn idiotic truckload of sh*t": when it breaks

Git is a fast, scalable, distributed revision control system with an
unusually rich command set that provides both high-level operations
and full access to internals.

Git is an Open Source project covered by the GNU General Public
License version 2 (some parts of it are under different licenses,
compatible with the GPLv2). It was originally written by Linus
Torvalds with help of a group of hackers around the net.

The user discussion and development of Git take place on the Git
mailing list -- everyone is welcome to post bug reports, feature

The maintainer frequently sends the "What's cooking" reports that
list the current status of various development topics to the mailing
list.  The discussion following them give a good reference for
project status, development direction and remaining tasks.
