Fixes signals004(threaded1,threaded2) on OS X 32.

I assume that this is what was intended.

sleep doesn't really work on GHC because it is always immediately
interrupted by SIGVTALRM used in the RTS.

I explained the problem in a comment and added a WARNING pragma.

usleep and nanosleep have a similar problem, but, since they have better
precision, they can be restarted, so they are not as unusable as sleep.

The other .Common modules aren't expose, and we think exposing this
one was a mistake.

They broken the build on OSX. See #2979.

Based on a patch from Arnaud Degroote <degroote@NetBSD.org> in
trac #5480.

It may depend on getSlaveTerminalName if !defined(HAVE_OPENPTY)

The new module System.Posix.ByteString provides exactly the same API
as System.Posix, except that:

  - There is a new type: RawFilePath = ByteString

  - All functions mentioning FilePath in the System.Posix API
    use RawFilePath in the System.Posix.ByteString API

  - RawFilePaths are not subject to Unicode locale encoding and
    decoding, unlike FilePaths.  They are the exact bytes passed to and
    returned from the underlying POSIX API.

  - Similarly for functions that deal in environment
    strings (System.Posix.Env): these use untranslated ByteStrings
    in System.Posix.Environment

  - There is a new function

     System.Posix.ByteString.getArgs :: [ByteString]

    returning the raw untranslated arguments as passed to exec() when
    the program was started.
