SOLARIS: support mmap() over 4GiB
When mmap() is issued for exactly 4GiB of a large AFS-resident file,
mmap() fails with ENOMEM. This is because the AFS code is handling the
requested length as u_int instead of size_t, resulting in a 0 being
passed back to the caller.
When mmap() is issued for non-multiples of 4GiB, the subsequent mapping
will not contain all the requested pages, and for the same reason - the
mapped size has been truncated to 32 bits. This results in SIGSEGV when
accessing the non-mapped page(s).
Fix the signature of afs_map() to specify the correct type for the length.
Thanks to Robert Milkowski for the report and diagnosis.
