(ITS#4723) SEGV in syncprov search

Actually, this could be it exactly. To my reading, the
0.9.8d tarball 
still defaults to (an extremely dangerous) getpid(). 2.3.30
never uses 
CRYPTO_set_id_callback. And the most recent thread I see on
the matter 
ended (http://www.ma
il-archive.com/openssl-devopenssl.org/msg21037.html) 
with an attitude of "Yeah, if anything, we should make
things break more 
frequently when there's no callback set." Perhaps we
should be adding one, 
with a bit of platform awareness through lutil?
