add preliminary sendfile (1.0.0) gem support

This still needs work and lots of cleanup, but the basics are
there.  The sendfile 1.0.0 RubyGem is now safe to use under MRI
1.8, and is superior to current (1.9.2-preview3) versions of
IO.copy_stream for static files in that it supports more
platforms and doesn't truncate large files on 32-bit platforms.

 * Split out NeverBlock into NeverBlockEventMachine and NeverBlockReactor
   NeverBlock will default to one of them (depending on NB upstream).
 
+* allow _OPTIONAL_ splice(2) with DevFdResponse under Linux
+  (splice is very broken under some older kernels)
+
+* use IO#sendfile_nonblock for EventMachine/Rev/Revactor/NeverBlock

+* Open file cache (idea from nginx), since sendfile (and IO.copy_stream)
+  allows pread(2)-style offsets

 * Improve test suite coverage.  We won't waste cycles with puny
   unit tests, only integration tests that exercise externally
   visible parts.
