add support COMPAT_LINUX for aarch64

Rename ipcall/socketcall specific defines to avoid conflict with
syscalls definitions. No functional changes.

remove some "inline" from functions which are defined in a .c file
but used elsewhere -- gcc-4.4.1 doesn't like it and I doubt it
had any effect

Remove clause 3 and 4 from TNF licenses

Convert all the system call entry points from:
int foo(struct lwp *l, void *v, register_t *retval)
to:
int foo(struct lwp *l, const struct foo_args *uap, register_t *retval)
Fixup compat code

Convert all the system call entry points from:
int foo(struct lwp *l, void *v, register_t *retval)
to:
int foo(struct lwp *l, const struct foo_args *uap, register_t *retval)
Fixup compat code to not write into 'uap' and (in some cases) to actually
pass a correctly formatted 'uap' structure with the right name to the
next routine.
A few 'compat' routines that just call standard ones have been deleted.
All the 'compat' code compiles (along with the kernels required to test
build it).
98% done by automated scripts.

Remove all the __P

Change "inline" back to "__inline" in .h files -- C99 is still too
new, and some apps compile things in C89 mode. C89 keywords stay.

As per core@.

merge ktrace-lwp.

First work on COMPAT_LINUX/amd64
Process startup and dynamiclinking work, but processes hang due to
Linux arch_prctl(2) not being really supported yet.

Merge the nathanw_sa branch.

Revert last changes:
Because "linux_ipccall.h" cannot be included before "sys/shm.h" and
"sys/shm.h" needs to be included after "opt_sysv.h" include "opt_sysv.h"
in "linux_ipccall.c" again.

Grab the sysv options.

Assign my copyright to TNF. Merge with others were appropriate.
Regen syscall files after script change.

Attempt to fix the mess.

Move linux/compat/linux_ipccall.h to multiarch. Defines for the IPC multiplexerand associated functions.

Implement the rest of the sysv ipc calls ({sem,msg}*())

Added Linux compat code.
