Small tweaks
Lots of new code imported.
Pipes cannot use SOCK_DGRAM. Back to SOCK_STREAM.

Fighting the good fight.
Move libfmt, libutf into subdirectories of lib9. Add poll-based socket i/o to libthread, so that we can avoid using multiple procs when possible, thus removing dependence on crappy pthreads implementations. Convert samterm, acme to the single-proc libthread. Bring libcomplete, acme up-to-date w.r.t. Plan 9 distribution.
More files related to user-level file servers.
Also add acme!
