Do not DWIM in userpath library under strict mode.
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.
