Add git-symbolic-ref
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.
