windows: set the child_pid property for all IPC pipes in uv_spawn

sunos: allow suppression of ifaddrs.h

Older Solaris versions do not have this feature. This allows
them to set SUNOS_NO_IFADDRS to allow libuv to build.

sunos: fix assertion errors in uv__finish_close

linux: fix typo in syscall name

unix, windows: update uv_fs_poll API

* the callback gets called only once on error, not repeatedly...

* ...unless the error reason changes from e.g. UV_ENOENT to UV_EACCES

* ...unless the error reason changes from e.g. UV_ENOENT to UV_EACCES

* the callback receives pointers to uv_statbuf_t objects so it can inspect what

unix, windows: add stat() based file watcher

Monitors a file path for changes. Supersedes ev_stat.

test: make the test-hrtime less likely to time out

windows: prevent accidental inheritance of sockets pending acceptance

unix: always set CLOEXEC flag for child process stdio FDs

unix: fix memory leak in libev

Not everything that identifies itself as glibc really is glibc.

unix: implement uv_disable_stdio_inheritance()

windows: implement uv_disable_stdio_inheritance

unix: make uv__nonblock() EINTR resilient

It's underspecified if and when ioctl(FIONBIO) or fcntl() can return EINTR.
Let's take the safe route.

unix: make uv__cloexec() EINTR resilient

It's somewhat underspecified if and when fcntl() can return EINTR. It never
does on Linux for F_GETFD or F_SETFD but let's not make any assumptio

unix: reset error status in uv_dlopen()

Fixes a bug where uv_dlopen() mistakenly reported failure because of previous
errors.

windows: remove run-time RB_INSERT check from release builds

linux: add eventfd and eventfd2 syscalls
