Instead of interning property names and comparing their string_pool
keys, look them up in a table by string length, which should be about
as fast.
Another small step towards removing dependence on string_pool
altogether.

Use strbufs and strings instead of interned strings for values of rev,
dump, and node fields that happen to be strings. After this change,
the only remaining string_pool use is for paths in the repo_tree API
and internals.
Functional change: treat an empty author, UUID, or URL as none at all.
So for example, in repos where the first revision has an empty
svn:author property, the first rev will be treated as by "nobody"
rather than by a person with empty name and email address created by
prepending an @ sign to the repository UUID.

obj_pool is overkill for this application: all that is needed is a
buffer that can resize from rev to rev to accomodate differently-sized
strings. In the spirit of commit deadcef4 (2010-11-06), use a strbuf
instead.
This is a small step towards removing dependence on obj_pool.h.

Currently buffer_copy_bytes does not report to its caller whether
it encountered an early end of file.
Add a return value representing the number of bytes read (but not
the number of bytes copied). This way all three unusual conditions
can be distinguished: input error with buffer_ferror, output error
with ferror(outfile), early end of input by checking the return
value.

Move from uint32_t to off_t as the fundamental unit of length used by
the line_buffer library. Performance would get worse if anything but
I think it's worth it for support of deltas that need to skip large
pieces (> 4 GiB).
Exception: buffer_read_string still takes a uint32_t, since it keeps
its result in an in-core obj_pool.
Callers still have to be updated to take advantage of this.

'git am --abort' is around for quite a long time now, and users should
normally not poke around inside the .git directory, yet the
documentation of 'git am' still recommends the following:
... if you decide to start over from scratch,
run `rm -f -r .git/rebase-apply` ...
Suggest 'git am --abort' instead.
It's not quite the same as the original, because 'git am --abort' will
restore the original branch, while simply removing '.git/rebase-apply'
won't, but that's rather a thinko in the original wording, because
that won't actually "start over _from scratch_".

When there are too many paths in the project, the number of rename source
candidates "git diff -C -C" finds will exceed the rename detection limit,
and no inexact rename detection is performed. We however could fall back
to "git diff -C" if the number of modified paths is sufficiently small.

Rebased to 'master' as the logic to use the result of this logic was
updated recently, together with the addition of eye-candy.
The return value from builtin_diff_files() is fed to diff_result_code()
by the caller, and all other callees like builtin_diff_index() do not
have their own call to diff_result_code(). Remove the duplicated one
from builtin_diff_files() and let the caller handle it.

Traditional "opportunistic index update" done by read-only "diff" and
"status" was about updating cached lstat(2) information in the index for
the next round. We missed another obvious optimization opportunity: when
there are racily clean entries that will cease to be racily clean by
updating $GIT_INDEX_FILE. Detect that case and write $GIT_INDEX_FILE out
to give it a newer timestamp.
Noticed by Lasse Makholm by stracing "git status" in a fresh checkout and
counting the number of open(2) calls.

When we had to refresh the index internally before running diff or status,
we opportunistically updated the $GIT_INDEX_FILE so that later invocation
of git can use the lstat(2) we already did in this invocation.
Make them share a helper function to do so.

If gitk is not available in the PATH, bisect ends up
exiting with the shell's 127 error code, confusing the git
wrapper into thinking that bisect is not a git command.
We already fallback to git-log if there doesn't seem to be a
graphical display available. We should do the same if gitk
is not available in our PATH at all. This not only fixes the
ugly error message, but is a much more sensible default than
failing to show the user anything.

When orphaning a commit on a detached HEAD, the warning
currently looks like:
Warning: you are leaving 3 commits behind, not connected to
any of your branches:
- commit subject 1
- commit subject 2
- commit subject 3
If you want to keep them by creating a new branch, this
may be a good time to do so with:
git branch new_branch_name 933a615ab0bc566dcfd8c01ec8af159f770d3fe5
Instead of using the "-" list, let's provide a more
traditional oneline format, with the abbreviated sha1 before
each subject. Users are accustomed to seeing commits in this
format, and having the sha1 of each commit can be useful if
you want to cherry-pick instead of creating a new branch.
The new format looks like:
