#123 Integer size mismatches around mmap64()

On 32-bit platforms with 64-bit I/O support in STLport, streamoff is 64 bits wide, but mmap64() takes a 32-bit memory block size. This causes warnings with Sun C++ 5.9 on Solaris if compiled with the +w2 warning option (which is the default in STLport).

This patch changes _M_mmap_len and various function arguments from 64-bit streamoff to 32-bit size_t.

Despite its name, the patch is not appropriate for the STLport 5.2 branch because it breaks binary compatibility.
