proc: Implement /proc/thread-self to point at the directory of the current thread
/proc/thread-self is derived from /proc/self. /proc/thread-self
points to the directory in proc containing information about the
current thread.
This funtionality has been missing for a long time, and is tricky to
implement in userspace as gettid() is not exported by glibc. More
importantly this allows fixing defects in /proc/mounts and /proc/net
where in a threaded application today they wind up being empty files
when only the initial pthread has exited, causing problems for other
threads.
