Subject: [PATCH] posix_wrap: tweaks in preparation for libtasn1

 - Define SIZEOF_UNSIGNED_LONG_INT, it's the same as
   SIZEOF_UNSIGNED_LONG.

 - Define WORD_BIT, the size in bits of an int. This is a defined
   in the Single Unix Specification and in gnulib's limits.h. gnulib
   assumes it's 32 bits on all our platforms, including 64 bit
   platforms, so we also use that value.

 - Provide strto[u]l[l] preprocessor macros that resolve to
   grub_strto[u]l[l]. To avoid gcrypt redefining strtoul, we
   also define HAVE_STRTOUL here.
