fsevents: remove kFSEventStreamCreateFlagNoDefer polyfill

The kFSEventStreamCreateFlagNoDefer flag is already
defined in CarbonCore/FSEvents.h since OS X 10.5.

Fixes #1000.
libuv: add more getaddrinfo errors
unix: fix accept() EMFILE error handling

Fix a bug that was introduced in commit 3ee4d3f ("unix, windows:
return error codes directly") and add a regression test for good
measure.

Hat tip to Fedor for pointing out the issue.

Fixes #1007.
test: back-port EMFILE test from master branch

Back-port the test from commit 27795cf from the master branch ("unix:
fix accept() EMFILE error handling").

gitignore: ignore *.pyc files

The gyp build on Windows produces a *.pyc file as of commit 991409e.
linux: fix up SO_REUSEPORT back-port

Commit 3d2c820 back-ports a patch from the master branch that disables
the use of SO_REUSEPORT on Linux for reasons mentioned in the commit
log.

Unfortunately, the back-port was incomplete; another setsockopt() call
site in src/unix/udp.c was overlooked.  This commit rectifies that.

Hat tip to Luca Bruno for helping troubleshoot the issue.
fsevents: fix subfolder check

First of all, a bit of explanation of what happens there:

1. FSEvents emits absolute paths to changed files or directories
2. We cut off the first part of such paths, which is equal to handle's
   real path ('/dir/subdir/subsubdir`, without trailing slash)
3. Then, if we are running in non-recursive mode, we discard paths that
   have slashes ('/') as a non-first character in them
build: make `./gyp_uv.py -f eclipse` work

The eclipse backend (like the ninja backend) does not support the
--generator_output switch.

fs-event: fix invalid memory access

file_info->FileName is not null terminated.
windows/timer: fix uv_hrtime discontinuity

Large performance counter frequency values would cause overflows, even
when 64-bit integers were used to do the multiplication with NANOSEC.
Fix this by using floating point math instead.
