This adds the counterpart of git-update-ref that lets you read
and create "symbolic refs". By default it uses a symbolic link
to represent ".git/HEAD -> refs/heads/master", but it can be compiled
to use the textfile symbolic ref.
The places that did 'readlink .git/HEAD' and 'ln -s refs/heads/blah
.git/HEAD' have been converted to use new git-symbolic-ref command, so
that they can deal with either implementation.

My stupidity deserved to be yelled at by Linus ... there is no reason
to require the working tree to be clean when merging -- the only
requirements are index to match HEAD commit and the paths involved in
merge are up to date in the working tree. Revert and cherry-pick are
just specialized forms of merge, and the requirements should be the
same.
Remove the 'general purpose routine to make sure tree is clean' from
git-sh-setup, to prevent me from getting tempted again.

CDPATH has two problems:
* It takes scripts to unexpected places (somebody had
CDPATH=..:../..:$HOME and the "cd" in git-clone.sh:get_repo_base
took him to $HOME/.git when he said "clone foo bar" to clone a
repository in "foo" which had "foo/.git"). CDPATH mechanism does
not implicitly give "." at the beginning of CDPATH, which is
the most irritating part.
* The extra echo when it does its thing confuses scripts further.
Most of our scripts that use "cd" includes git-sh-setup so the problem
is primarily fixed there. git-clone starts without a repository, and
it needs its own fix.

As promised, this is the "big tool rename" patch. The primary differences
since 0.99.6 are:
(1) git-*-script are no more. The commands installed do not
have any such suffix so users do not have to remember if
something is implemented as a shell script or not.
(2) Many command names with 'cache' in them are renamed with
'index' if that is what they mean.
There are backward compatibility symblic links so that you and
Porcelains can keep using the old names, but the backward
compatibility support is expected to be removed in the near
future.
