Re-backport all the rpc stuff from glibc 2.2.5. This allows us to make this

junk (and I do mean that ;-) thread safe without undue pain.  Adds 12k worth to
the code size I'm afraid, but since I never use NFS and therefore never include
this stuff, I guess thats acceptable.  I still need to enable the multi-threaded
bits...
