Add support for COMPAT6 syscalls.
Also, change the visibility of compat syscalls a slightly. Compat
syscalls were missing from 'syscalls.h' entirely. This additionally adds
them with their compat prefix. eg: SYS_freebsd6_mmap.
Also, the syscalls.c names strings have different prefixes to differentiate
syscalls. Instead of several "old.mmap" strings, there will now be a
"compat.mmap" and "compat6.mmap" etc. Before, both would have had the
same "old.mmap" label.
