From: Stacey Son <sson@FreeBSD.org>

Add some trivial misc system calls: stub implementations for quotactl(2)
and reboot(2) syscall; a trivial do_bsd_getdtablesize that calls
getdtablesize(2).

We now want SPDX-License-Identifier on all new files, and to *not* include the 
boilerplate.  Should be diagnosed by checkpatch.pl now too.

I had noted this in my cover letter. I cannot change the copyright and
license grant for code I do not own. I've asked Stacey to give me the OK
(and to do it globally so I can fix it everywhere). He's usually
responsive. Both here and in bsd-misc.c. So I'll fix this in v2 if I hear
back in time.
