Fix typo; timotimo++.
replace $(PREFIX) by @prefix@ which will result in a path string

So we don't end up with '$(PREFIX)' in flags exposed to perl6, which will
not be resolvable at that point anymore.
Stub timer op, for creating a timer.
Add a libuv-managed event loop thread.

This will be used in timers, async I/O, file system notifications, and
so forth. It will deliver completion notifications into a queue - one
that is presumably being used as a thread pool input stream.
Implement timers.

Doesn't do the required cleanup or have cancellation support yet, but
it's enough to pass an unfudged scheduler.t.
small cleanups, and removed a needless MVMROOT
re-add setup var
revert cleanups in setup_work function
Stub various async ops.
Implement nqp::signal, support various signals.
Only support SIGBREAK where available.

Should hopefully unbreak the build in places it ain't.
Add async read/write sections to IO op table.
Stub async socket listen/connect.

Just throws over being NYI so far.
Implement async read/write ops.

No I/O handle type actually supports them yet, but this gets the
wiring for them in place.
Fix HLL mapping of type objects.
Make host resolution more widely available.

Want to re-use it in async sockets.
Got asynchronous socket connect in place.
Add asynchronous socket write (string and bytes).
Implement chars case of async socket reads.
Implement async server sockets.
