cleaning up syscalls in preparation for x86_64 port
- hide all the legacy xxxxxx32 name cruft in syscall.h so the actual
source files can be clean and uniform across all archs.
- cleanup llseek/lseek and mmap2/mmap handling for 32/64 bit systems
- alternate implementation for nice if the target lacks nice syscall
