Patch for sub-second resolution in stat(2)

["Conrad Scott" <Conrad dot Scott at dsl dot pipex dot com>]

After Chris's exciting news that my assignment has reached RedHat, here's a
patch!

This adds sub-second resolution to the access, modification, and creation
times returned by stat(2) etc. I thought this would make a nice companion to
Corinna's work on making other things in stat(2) be 64-bit.

Also, I was having trouble with a makefile where the commands could execute
in less than a second leading to irregular breakage: this patch fixes that.

I've checked that this maintains both source and binary compatibility (tho'
it does add macros for st_mtime etc. to hide the indirection involved).

I'm unclear whether this is the best naming / type scheme but it is one
recognised by both the make and fileutils packages available from the cygwin
setup (i.e. make this patch and re-compile those packages and they detect
the new fields).

I've provided two separate patches: one for types.h (in the newlib.patch)
and one for the cygwin sources (in winsup.patch). The changelog entries are:

newlib:

Changelog message:
* types.h (timespec_t timestruc_t): New typedefs.

winsup/cygwin:

* fhandler.cc (fhandler_base::fstat):
* fhandler_disk_file.cc (fhandler_disk_file::fstat_helper):
* fhandler_process.cc (*fhandler_process::fstat)
