Remove the old COMPAT_23 SysV IPC structures and the never implemented

Rototill system V message queues.

No longer allocate a static amount of memory for messages in MD
boot path; message queues, message metadata, and message data now
all use dynamic memory, which means that runtime sysctls should now
be trivial to implement.

Since I'm going to be around all week to fix any breakage, this should
probably just go in now.

Rename structs oipc_perm, omsqid_ds, osemid_ds, oshmid_ds to ipc_perm23,
etc to avoid confusion and for consistency with the *35 ones.
Remove *n2o functions that don't belong outside of compat.

Because mode_t is used in struct ipc_perm we need new versions of
the msgctl, semctl, and shmctl system calls. This moves the old
versions to COMPAT_35 and adds new ones.

WARNING: While this fixes things like shared memory in the X server
for old (pre-mode_t change) binaries, it will break binaries that
use shared memory built between the time of the mode_t change (Jul
13th) and now. If you rebuild X during that interval you will need
to do it again after updating the rest of userland.

Move the guts of the {sem,msg,shm}ctl system calls into a new function
which also takes two function pointers for copyin/copyout. For the
real syscalls these are just the normal copyin/copyout functions.
For the compat routines, these are funtions that convert between
the new and old foo_ds structs automagically. OK deraadt@

Change all variables definitions (int foo) in sys/sys/*.h to variable
declarations (extern int foo), and compensate in the appropriate locations.

First round of __P removal in sys

branches: 1.7.4;
sysctl() support for getting the SYSV *info structs and the associated
SYSV structs. To be used by ipcs(1). Based on work by simonb@netbsd.org

Don't allocate globals in include files, use extern declarations.
Move the actual variables into their respective .c files.
As a bonus, remove semmap which is not used.

branches: 1.5.8;
do not export old structures to userland

change ipc.h to use uid_t and friends, and then build compat system calls for the old ushort based ipc.h
