- Put Darwin syscall DECL_TEMPLATEs in syscall order.
- Removed the "sys_" prefix from Darwin-specific wrappers, it's not
necessary. Renamed a couple of other wrappers similarly.
- Removed the sys_fcntl64 Darwin wrapper, it was unused.
- Improved some code layout.
Overall this removes 6 "DDD"/"GrP" fixme comments.
