David Wilson a18a083c94 issue #260: avoid start_transmit()/on_transmit()/stop_transmit()
Previous transmit sequence was:
        Router._async_route -> Stream._send -> Broker._start_transmit ->
        Broker.loop -> Stream.on_transmit -> socket.write ->
        Broker.stop_transmit

New sequence, when socket buffer can hold message is:
        Router._async_route -> Stream._send -> socket.write

David Wilson 0c0d34241b core: Latch._wake improvements
os.write() can fail with EINTR due to signals, so wrap it in
io_op(). Closes #483.

Masking EBADF looks like it is/was almost certainly papering over a bug,
remove it and suffer the bug reports. Closes #495.

David Wilson 9aa845669c issue #413: don't double-propagate DEL_ROUTE to parent.
propagate_up() sends ADD_ROUTE and DEL_ROUTE

propagate_down() sends only DEL_ROUTE, but didn't bother checking if
up() had sent it already.

David Wilson be6ab52fe1 issue #488: fix shutdown damage caused in 6ca2677de5
os._exit() subverted calm shutdown, meaning unix.Listener never had a
chance to cleanup its socket.

Move unix.Listener socket cleanup into its class so it is automatic
during shutdown, rather than cutpasted for each consumer.

Disable the watcher thread in the MuxProcess, it is useless.

Add .sock extension to /tmp/mitogen_unix_*, so we can write a test.

This is mostly to avoid ugly debugging that depends on the state of GC.
Discard sides from _fork_refs after they have been closed.
