d556fae2c0 Support 'master@2 hours ago' syntax
Extended sha1 expressions may now include date specifications
which indicate a point in time within the local repository's
history.  If the ref indicated to the left of '@' has a log in
$GIT_DIR/logs/<ref> then the value of the ref at the time indicated
by the specification is obtained from the ref's log.

6de08ae688 Log ref updates to logs/refs/<ref>
If config parameter core.logAllRefUpdates is true or the log
file already exists then append a line to ".git/logs/refs/<ref>"
whenever git-update-ref <ref> is executed.  Each log line contains
the following information:

  oldsha1 <SP> newsha1 <SP> committer <LF>

where committer is the current user, date, time and timezone in
the standard GIT ident format.  If the caller is unable to append
to the log file then git-update-ref will fail without updating <ref>.

An optional message may be included in the log line with the -m flag.

4bd18c43d9 Improve abstraction of ref lock/write.
Created 'struct ref_lock' to contain the data necessary to perform
a ref update.  This change improves writing a ref as the file names
are generated only once (rather than twice) and supports following
symrefs (up to the maximum depth).  Further the ref_lock structure
provides room to extend the update API with ref logging.

a62be77f5e Add "--branches", "--tags" and "--remotes" options to git-rev-parse.
"git branch" uses "rev-parse --all" and becomes much too slow when
there are many tags (it scans all refs).  Use the new "--branches"
option of rev-parse to speed things up.

723c31fea2 Add "git_path()" and "head_ref()" helper functions.
"git_path()" returns a static pathname pointer into the git directory
using a printf-like format specifier.

"head_ref()" works like "for_each_ref()", except for just the HEAD.

944d858969 Fix up "for_each_ref()" to be more usable, and use it in git-fsck-cache
It needed to take the GIT_DIR information into account, something that
the original receive-pack usage just never cared about.

8a65ff7666 Generalize the "show each ref" code in receice-pack
This turns it into a generic "do xyz for each ref" library function.

95fc75129a [PATCH] Operations on refs
This patch adds code to read a hash out of a specified file under
{GIT_DIR}/refs/, and to write such files atomically and optionally with an
compare and lock.
