reintroduce SLEEPY_PENGUIN_VERSION constant
We unfortunately need it since we switched to the
per-thread epoll_wait structures.

timerfd: remove unusable constants (never released)
timerfd currently (Linux 3.3.x) only supports CLOCK_REALTIME and
CLOCK_MONOTONIC, and not every single clock supported by POSIX
clocks.

epoll: update comment on free(NULL) usage
It's POSIX, and since epoll is Linux-only and Linux
uses glibc which is pretty up-to-date w.r.t POSIX,
we don't have to worry...

teset: epoll used as a queue
This is a testcase I wrote a few months ago

epoll: use per-thread data structure for concurrent Epoll#wait
This allows multiple threads to park on Epoll#wait (without
holding onto the GVL). This allows a single, one-shot notification
to wake up a single thread (another notification to a different
IO object would wake up another thread).
This allows using the same multi-threaded, EPOLLONESHOT-based
design as cmogstored:

test_epoll: disable expensive test without STRESS
Tests run a lot faster, now, and this isn't functionality
we have to worry about often now that I better understand
MRI internals.

sleepy_penguin.h: add prototype for rb_thread_io_blocking_region
This function is exposed in the libruby-static archive for
Ruby 1.9.3, but there is no publically-declared prototype for it.

epoll: split out ugly green thread code
It's ugly and confusing to look at, so split it out.

test: new testcase for edge-triggered accept
Found uncommited in my working directory, I can't remember
when/where I wanted to test this, but we might as well for
documentation purposes...

use sleepy.penguin@librelist.org address instead of .com
Neither we nor librelist are commercial projects, so use
the TLD preferred for non-profit entities.

disable SignalFD interface
It's a waste of memory to have something that has no chance
of working reliably with any existing Ruby runtimes.

rb_update_max_fd() support for epoll
This is the only descriptor we manage ourselves and don't
use IO.for_fd with (epoll is quite "special" wrt fork).

timerfd: add new constants from 2.6.39 and 3.0
We still need to document these.

test_epoll: add level trigger test
Just to ensure we still work with level triggered usage.
