ffi: precompute member offsets in struct type.

This change will make bitfield support easier.

* ffi.c (struct smemb): New member, offs.
(ffi_struct_in, ffi_struct_put, ffi_struct_out,
ffi_struct_get, ffi_struct_release): For each member, refer to
the offset in the memb array, rather than calculating it
on-the-fly.
(make_ffi_type_struct): Calculate the offset for each member.
This is exactly the same as the total_size calculation before;
just the name is changed to offs, and bit operations are used
for the alignment calculations.
