32619: vcs_info svn: Use the revision of cwd

Previously, the value of the wc root would be used.  In Subversion,
it makes more sense to use the revision of cwd, since all commands
(e.g., 'svn ci', 'svnversion') operate only on cwd and below, not on
wcroot and below.
32621: vcs_info svn: 'Fix set-branch-format' when in subdirs

The previous code would fail to detect the wcroot with Subversion 1.7+
when cwd is at least two levels below the root (i.e., ../../.svn exists
and ../.svn doesn't), and would then pass to the hook the revision and
basename of cwd rather than of the wcroot.

32662: vcs_info git: Fix stagedstr for empty repos

In empty repositories, HEAD is an unresolvable symbolic ref.  Start computing
stagedstr/unstagedstr in that case; for the former, use a different method
than the non-empty-repository case.
