This should force git-daemon administrator's job a bit harder
because the exact paths need to be given in the whitelist, but
at the same time makes the auditing easier.

This moves validate_symref() from refs.c to path.c, because we
need to link path.c with git-daemon for its "enter_repo()", but
we do not want to link the daemon with the rest of git libraries
and its requirements.

This is meant for the end user, who cannot be expected to edit
.git/config by hand.

Example:

	git-config-set core.filemode true

will set filemode in the section [core] to true,

	git-config-set --unset core.filemode

will remove the entry (failing if it is not there), and

	git-config-set --unset diff.twohead ^recar

will remove the unique entry whose value matches the regex "^recar"
(failing if there is no unique such entry).

It is just a light wrapper around git_config_set() and

The function git_config_set() does exactly what you think it does.
Given a key (in the form "core.filemode") and a value, it sets the
key to the value. Example:

	git_config_set("core.filemode", "true");

The function git_config_set_multivar() is meant for setting variables which
can have several values for the same key. Example:

	[diff]
		twohead = resolve
		twohead = recarsive

the typo in the second line can be replaced by

	git_config_set_multivar("diff.twohead", "recursive", "^recar");

The third argument of the function is a POSIX extended regex which has to
match the value. If there is no key/value pair with a matching value, a new
key/value pair is added.

These commands are also capable of unsetting (deleting) entries:

	git_config_set_multivar("diff.twohead", NULL, "sol");

will delete the entry

		twohead = resolve

The current rebase implementation finds commits in our tree but
not in the upstream tree using git-cherry, and tries to apply
them using git-cherry-pick (i.e. always use 3-way) one by one.

Which is fine, but when some of the changes do not apply
cleanly, it punts, and punts badly.

Suppose you have commits A-B-C-D-E since you forked from the
upstream and submitted the changes for inclusion.  You fetch
from upstream head U and find that B has been picked up.  You
run git-rebase to update your branch, which tries to apply
changes contained in A-C-D-E, in this order, but replaying of C
fails, because the upstream got changes that touch the same area
from elsewhere.

Now what?

It notes that fact, and goes ahead to apply D and E, and at the
very end tells you to deal with C by hand.  Even if you somehow
managed to replay C on top of the result, you would now end up
with ...-B-...-U-A-D-E-C.

Breaking the order between B and others was the conscious
decision made by the upstream, so we would not worry about it,
and even if it were worrisome, it is too late for us to fix now.
What D and E do may well depend on having C applied before them,
which is a problem for us.

This rewrites rebase to use git-format-patch piped to git-am,
and when the patch does not apply, have git-am fall back on
3-way merge.  The updated diff/patch pair knows how to apply
trivial binary patches as long as the pre- and post-images are
locally available, so this should work on a repository with
binary files as well.

The primary benefit of this change is that it makes rebase
easier to use when some of the changes do not replay cleanly.
In the "unapplicable patch in the middle" case, this "rebase"
works like this:

 - A series of patches in e-mail form is created that records
   what A-C-D-E do, and is fed to git-am.  This is stored in
   .dotest/ directory, just like the case you tried to apply
   them from your mailbox.  Your branch is rewound to the tip of
   upstream U, and the original head is kept in .git/ORIG_HEAD,
   so you could "git reset --hard ORIG_HEAD" in case the end
   result is really messy.

 - Patch A applies cleanly.  This could either be a clean patch
   application on top of rewound head (i.e. same as upstream
   head), or git-am might have internally fell back on 3-way
   (i.e.  it would have done the same thing as git-cherry-pick).
   In either case, a rebased commit A is made on top of U.

 - Patch C does not apply.  git-am stops here, with conflicts to
   be resolved in the working tree.  Yet-to-be-applied D and E
   are still kept in .dotest/ directory at this point.  What the
   user does is exactly the same as fixing up unapplicable patch
   when running git-am:

   - Resolve conflict just like any merge conflicts.
   - "git am --resolved --3way" to continue applying the patches.

 - This applies the fixed-up patch so by definition it had
   better apply.  "git am" knows the patch after the fixed-up
   one is D and then E; it applies them, and you will get the
   changes from A-C-D-E commits on top of U, in this order.

I've been using this without noticing any problem, and as people
may know I do a lot of rebases.

When doing something like

	git fetch --tags origin

the excessively verbose output of git fetch makes the result totally
unreadable. It's impossible to tell if it actually fetched anything new or
not, since the screen will fill up with an endless supply of

   ...
   * committish: 9165ec17fde255a1770886189359897dbb541012
     tag 'v0.99.7c' of master.kernel.org:/pub/scm/git/git
   * refs/tags/v0.99.7c: same as tag 'v0.99.7c' of master.kernel.org:/pub/scm/git/git
   ...

and any new tags that got fetched will be totally hidden.

So add a new "--verbose" flag to "git fetch" to enable this verbose mode,
but make the default be quiet.

NOTE! The quiet mode will still report about new or changed heads, so if
you are really fetching a new head, you'll see something like this:

   [torvalds@g5 git]$ git fetch --tags parent
   Packing 6 objects
   Unpacking 6 objects
    100% (6/6) done
   * refs/tags/v1.0rc2: storing tag 'v1.0rc2' of master.kernel.org:/pub/scm/git/git
   * refs/tags/v1.0rc3: storing tag 'v1.0rc3' of master.kernel.org:/pub/scm/git/git
   * refs/tags/v1.0rc1: storing tag 'v1.0rc1' of master.kernel.org:/pub/scm/git/git

which actually tells you something useful that isn't hidden by all the
useless crud that you already had.

Extensively tested (hey, for me, this _is_ extensive) by doing a

   rm .git/refs/tags/v1.0rc*

and re-fetching with both --verbose and without.

NOTE! This means that if the fetch didn't actually fetch anything at all,
git fetch will be totally quiet. I think that's much better than being so
verbose that you can't even tell whether something was fetched or not, but
some people might prefer to get a "nothing to fetch" message in that case.

This allows people to use syntax like "last thursday" for the approxidate.

(Or, indeed, more complex "three thursdays ago", but I suspect that would
be pretty unusual).

NOTE! The parsing is strictly sequential, so if you do

	"one day before last thursday"

it will _not_ do what you think it does. It will take the current time,
subtract one day, and then go back to the thursday before that. So to get
what you want, you'd have to write it the other way around:

	"last thursday and one day before"

which is insane (it's usually the same as "last wednesday" _except_ if
today is Thursday, in which case "last wednesday" is yesterday, and "last
thursday and one day before" is eight days ago).

Similarly,

	"last thursday one month ago"

will first go back to last thursday, and then go back one month from
there, not the other way around.

I doubt anybody would ever use insane dates like that, but I thought I'd
point out that the approxidate parsing is not exactly "standard English".

Side note 2: if you want to avoid spaces (because of quoting issues), you
can use any non-alphanumberic character instead. So

	git log --since=2.days.ago

works without any quotes.
