In sysproto.h, stop including sys/acl.h as syscall defintions now use
__acl* types from sys/_types.h. Add sys/types.h to provide types
previously provided by sys/param.h (via sys/acl.h).

For the uncommon items: Go through the tree and remove sccs tags that
didn't fit any nice pattern. If in the neighborhood, other SCM tags were
removed when they were detritis of long-ago CVS somehow in the early
mists of the project. Some adjacent copyrights stringswere removed (they
duplicated the copyright notices in the file). This also removed
non-standard formations of omission of SCCS tags (usually by adding an
extra #if 0 somewhere.
After this commit, a number of strings tagged with the 'what' @(#)
prefix remain, but they are primarily copyright notices.

We only want to produce syscall.mk for the main syscall table so default
to not producing it (send it to /dev/null) and add a syscalls.conf to
sys/kern to trigger the creation of sys/sys/syscall.mk. This eliminates
the need for entries in other syscalls.conf files and is a cleaner
pattern going forward.

Perhaps, this does not makes much sense as destroyng %rcx declared by
the x86_64 Linux syscall ABI. However,:
a) if we get a signal while we are in the kernel, we should restore
tf_rcx when preparing machine context for signal handlers.
b) the Linux world is strange, someone can depend on %rcx value
after syscall, something like go.
