o  Introduce private types for use in linux syscalls for two reasons:    1. establish type independence for ease in porting and,    2. provide a visual queue as to which syscalls have proper       prototypes to further cleanup the i386/alpha split.    Linuxulator types are prefixed by 'l_'. void and char have not    been "virtualized".

o  Remove dummy functions for syscalls that are now truely
   unimplemented.

o  Rename syscalls so they match the names used in the Linux kernel.
   Also, provide more accurate prototypes. This generally improves
   cross-referencing and reduces head-scratching.

o  Provide seperate implementations for the 16-bit uid_t and gid_t
   based syscalls as Linux used to have. The new 32-bit uid_t and
   gid_t based syscalls now map to their FreeBSD equivalents.

o  Fix the linux_ipc syscall so that it doesn't force the shm*, sem*
   and msg* syscalls to have the same syscall. The prototypes for
   these syscalls now match the those used on Alpha. While here,
   add the same kludge for MSGRCV as is present in the Linux kernel.

o  Implement the following syscalls:
     linux_stat64, linux_lstat64 and linux_fstat64
     linux_sysctl

o  Added syscalls numbered 198 - 221. This include:
     - the 32-bit uid_t and gid_t bases syscalls
     - 64-bit file offset/size based syscalls
