Proposal: Add CUSeconds, CSUSeconds to Foreign.C.Types, and fix definition of CTimeval

[Ian Lynagh]

Hi all,

This is a proposal to add CUSeconds, CSUSeconds to Foreign.C.Types
(which are Haskell versions of the C useconds_t and suseconds_t types),
and fix the definition of CTimeval to use CTime and CSUSeconds rather
than CLong.

The C types are specified here:
    http://pubs.opengroup.org/onlinepubs/009695399/basedefs/sys/time.h.html

This will fix a bug in getCPUTime on OS X.

Patches, from William Knop, to implement this are here:

Discussion deadline: 7 May 2011
