use sy_call() so that l->l_sysent gets set, so that we can autoload modules
that define new syscalls properly.

Convert to new 2 clause license

Remove the 'args' parameter to 'trace_exit()' it is no longer used.
Instead of passing the (un)real system call code and syscall table pointer,
just pass the number of arguments - which is what ktrace really wants.

Remove systrace. Ok core@.

Further constification of the syscall args buffer.
It will get __UNCONST() applied in the systrace code if/when systrace tries
to change the arguments.  This sucks since the syscall args might be in
the trap frame, and the syscall might return ERESTART so the restarted call
would use the wrong arguments.
OTOH systrace() (as a security measure) is almost impossible to implement
for a threaded app (validated filenames can be changed before namei() reads
them into memory).
The current code is just plain broken for threaded apps - data that needs
to be lwp-specified is proc-specific.
I believe ad is planning to nuke systrace ...

Add a few buckets of 'const' and 'static' to the system call trace code.
sys_trace() still needs to be able to update the syscall args.

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.

Add MI implementations of the indirect stystem call functions sys_syscall()
and sys___syscall().
These functions are only used if the MI system call entry code doesn't
special-case the relevant entries.
