We tightened the refspec validation code in an earlier commit ef00d150
(Tighten refspec processing, 2008-03-17) per my suggestion, but the
suggestion was misguided to begin with and it broke this usage:

    $ git push origin HEAD~12:master

The syntax of push refspecs and fetch refspecs are similar in that they
are both colon separated LHS and RHS (possibly prefixed with a + to
force), but the similarity ends there.  For example, LHS in a push refspec
can be anything that evaluates to a valid object name at runtime (except
when colon and RHS is missing, or it is a glob), while it must be a
valid-looking refname in a fetch refspec.  To validate them correctly, the
caller needs to be able to say which kind of refspecs they are.  It is
unreasonable to keep a single interface that cannot tell which kind it is
dealing with, and ask it to behave sensibly.

This commit separates the parsing of the two into different functions, and
clarifies the code to implement the parsing proper (i.e. splitting into
two parts, making sure both sides are wildcard or neither side is).

This happens to also allow pushing a commit named with the esoteric "look
for that string" syntax:

    $ git push ../test.git ':/remote.c: Fix overtight refspec:master'

The fast-import documentation currently does not document the behaviour
of "merge" when there is no "from" in a commit.  This patch adds a
description of what happens: the commit is created with a parent, but
no files.  This behaviour is equivalent to "from" followed by
"filedeleteall".

For symbolic refs, a sane notion of being "stale" is that the ref
they point to no longer exists.  Since this is checked already,
"remote show" does not need to show them at all.

Incidentally, this fixes the issue that "HEAD" was shown as a
stale ref by "remote show" in a freshly cloned repository.

The gc.auto configuration variable is somewhat ambiguous now that there
is also a gc.autopacklimit setting. Some users may assume that it controls
all auto-gc'ing. Also, now users must set two configuration variables to
zero when they want to disable autopacking. Since it is unlikely that users
will want to autopack based on some threshold of pack files when they have
disabled autopacking based on the number of loose objects, be nice and allow
a setting of zero for gc.auto to disable all autopacking.

The revision limiter uses the commit date to decide when it has seen
enough commits to finalize the revision list, but that can get confused
if there are incorrect dates far in the past on some commits.

This makes the logic a bit more robust by

 - we always walk an extra SLOP commits from the source list even if we
   decide that the source list is probably all done (unless the source is
   entirely empty, of course, because then we really can't do anything at
   all)

 - we keep track of the date of the last commit we added to the
   destination list (this will *generally* be the oldest entry we've seen
   so far)

 - we compare that with the youngest entry (the first one) of the source
   list, and if the destination is older than the source, we know we want
   to look at the source.

which causes occasional date mishaps to be handled cleanly.

This changes the pattern matching code to not store the required final
/ before the *, and then to require each side to be a valid ref (or
empty). In particular, any refspec that looks like it should be a
pattern but doesn't quite meet the requirements will be found to be
invalid as a fallback non-pattern.

Currently when checking out an entry "path", we try to unlink(2) it first
(because there could be stale file), and if there is a directory there,
try to deal with it (typically we run recursive rmdir).  We ignore the
error return from this unlink because there may not even be any file
there.

However if you are root on Solaris, you can unlink(2) a directory
successfully and corrupt your filesystem.

This moves the code around and check the directory first, and then
unlink(2).  Also we check the error code from it.

When a merge result creates a new file, and when our side already has a
file in the path, taking the merge result may clobber the untracked file.
However, the logic to detect this situation was totally the wrong way.  We
should complain when the file exists, not when the file does not exist.

* jc/makefile:
  Makefile: flatten enumeration of headers, objects and programs
  Makefile: DIFF_OBJS is not special at all these days

In commit 34110cd4 ("Make 'unpack_trees()'
have a separate source and destination index") I introduced a really
stupid bug in that it would always add merged entries with the CE_UPDATE
flag set. That caused us to always re-write the file, even when it was
already up-to-date in the source index.

Not only is that really stupid from a performance angle, but more
importantly it's actively wrong: if we have dirty state in the tree when
we merge, overwriting it with the result of the merge will incorrectly
overwrite that dirty state.

This trivially fixes the problem - simply don't set the CE_UPDATE flag
when the merge result matches the old state.

Creating a branch in fast-import and then resetting it without making
any further commits to it currently causes an error message at the
end of the import.

This error is triggered by cvs2svn's git backend, which uses a
temporary fixup branch when it creates tags, because the fixup branch
is reset after each tag.

This patch prevents the error, allowing "reset" to be used to delete
temporary branches.

When rebasing changes that contain issues that the pre-commit hook flags
as problematic, the rebase cannot be continued.  However, rebase is about
transplanting commits that are already made with as little distortion as
possible, and pre-commit check should not interfere.
