teach add_submodule_odb() to look for alternates

Since we allow to link other object databases when loading a submodules
database we should also load possible alternates.

diff --no-index: reset temporary buffer lengths on directory iteration

Commit 875b91b (diff --no-index: use strbuf for temporary pathnames,
2012-04-25) introduced a regression when using diff --no-index with
directories.  When iterating through a directory, the switch to strbuf
from heap-allocated char arrays caused paths to form like 'dir/file1',
'dir/file1file2', rather than 'dir/file1', 'dir/file2' as expected.

Avoid this by resetting the paths variables to their original length
before each iteration.

diff --no-index: don't leak buffers in queue_diff

queue_diff uses two strbufs, and at the end of the function
strbuf_reset was called.  This only reset the length of the buffer -
any allocated memory was leaked.  Using strbuf_release fixes this.

archive: simplify refname handling

There is no need to build a copy of the relevant part of the string just
to make sure we have a NUL-terminated string.  We can simply pass the
length of the interesting part to dwim_ref() instead.

rev-parse doc: --git-dir does not always show a relative path

The description was misleading because it lead the reader to believe
that --git-dir would always show a relative path when, in fact, the
actual behaviour does not guarantee this.

Rather, it was intended that the advice be given that if a relative
path is shown, then the path is relative to the current working
directory and not some other directory (for example, the root of the
working tree).

Fix t3411.3 to actually rebase something

The test intends to rebase a branchy history onto a later commit, but it
forgot to reset HEAD back to an earlier commit before it set up the side
branches. In the end, every "rebased" commit was only a fast-forward and
the 'rebase -p' did not change the commit graph at all. Insert the missing
checkout that moves to an earlier commit.

osxkeychain: pull make config from top-level directory

The default compiler and cflags were mostly "works for me"
when I built the original version. We need to be much less
careful here than usual, because we know we are building
only on OS X.  But it's only polite to at least respect the
CFLAGS and CC definitions that the user may have provided
earlier.

While we're at it, let's update our definitions and rules to
be more like the top-level Makefile; default our CFLAGS to
include -O2, and make sure we use CFLAGS and LDFLAGS when
linking.
