What happens right now if two tag readers are trying to upgrade to write-locks at the same time? Can they both have a read lock in the same directory and thus each prevent the other from upgrading to a write-lock?

Modified: src ChangeLog lock.c tag.c
Log:
* lock.c (readers_exist): Ignore our own read lock, if any, to
allow upgrading an existing read lock to a write lock.
* tag.c (rtag_proc, rtag_fileproc, tag_fileproc): Rather than
locking the entire tree, have start_recursion establish read
locks and then upgrade the read lock to a write lock (so only
one directory is locked at a time).
