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.
