Revert "unix: reopen tty as /dev/tty"

This reverts commit 31f9fbce6321e2a26ab6d6c2d404aba1a7f161a7.

The reverted commit depends on commit 5da380a ("use select() for specific fds
on OS X") which polls /dev/tty file descriptors in a separate thread to work
around deficiencies in the kqueue API on OS X.

Unfortunately, 5da380a has a bug that effectively makes the select() thread
busy-loop. Revert this commit for now.

Export compile-time defines that influence the size of struct stat.

This should avoid sizeof(struct stat) mismatches between libuv and dependent

On OS X, _DARWIN_USE_64_BIT_INODE=1 is also exported.

unix: do not set environ unless one is provided

Currently, `uv_spawn` will set `environ` to the value of `options.env`, even if
`options.env` is `NULL`. This results in child processes for whom `environ ==
NULL`, which can cause a variety of unexpected issues.

This is a back-port of commit 1d85815 from the master branch.

Pro-actively ignore UV_ECANCELED errors. They're not actually emitted right now
because there's only ever one pending write but let's be forward compatible.

Revert "unix: avoid iterating over all async handles"

This reverts commit 209abbab27abdc63200cbd707f72fed4245ab4d0.

Fixes the following SIGSEGV:

It looks like the async handle gets closed or otherwise becomes invalid before
the sweep is executed.

Fixes #603.

linux: use /proc/cpuinfo for CPU frequency

Obtain the CPU frequency from /proc/cpuinfo because there may not be any
cpufreq info available in /sys. This also means that the reported CPU speed
from now on is the *maximum* speed, not the *actual* speed the CPU runs at.

This change only applies to x86 because ARM and MIPS don't report that
information in /proc/cpuinfo.
