f374bfcd3c Implement compile time debug support for spinlocks. 
Simplify the atomic lock prototype, removing the lock value.

Delete the unlock prototypes that are not required.

7d24d0302f Delete the atomic unlock function since it is no longer required. 
Simplify the atomic lock to just write a value of 1 to the lock instead
of taking the value passed by the caller (which just confused things).

70c9f9745b Quick fixes for the mtree bootstrap: 
- don't announce `mtree' as `mtools'.
- don't install to ${DESTDIR}/usr/sbin (which often doesn't exist if
  DESTDIR is set and may be read-only if DESTDIR is not set).
- install to (${WORLDTMP}/usr/sbin so that the new mtree is actually
  in $PATH if DESTDIR is set.
- don't use the host make or the host sys.mk.  This is probably
  unimportant.
- use a temporary obj dir like the one for `make'.  This was mainly
  necessary because I forgot to remove the MAKEOBJDIRPREFIX unsetting
  which was just a bug for mtree.  A non-quick fix would handle mtree
  more like a bootstrap tool (the only additional complications are to
  create ${BINDIR} and avoid excessive cleaning).  Except a non-quick
  fix would change much more.

67d3ec9a0f If we get back too much data to fit in result, return NULL. This avoids 
a buffer overflow, but might negatively impact those hosts who have
enough aliases to fill MAXHOSTNAMELEN * 2 characters in them.

Good candidate for merging back into -stable.  Lightly tested by me, but
it came from OpenBSD a while ago.

d944ccabfc Use correct size for readlink buffer. This is the size of the 
buffer -1 since readlink adds its own NUL to the end.

fae4b464e3 Use mkstemp rather than mktemp for yacc's temp files. This change was made 
to OpenBSD a long time ago and to my tree shortly thereafter.  I think theo
made this change, or one similar to it, but I could be wrong.

448b84a0e4 o Use snprintf rather than sprintf 
o Add more checks for buffer overflows
o Use snprintf rather than strcat/cpy and have better checks for max
  length exceeded.

Most of these changes are not exploitable buffer overruns, but it never
hurts to be safe.

e7c1c309fa Don't generate COMPAT_43 cruft if there are no COMPAT_43 syscalls. 
In particular, don't generate an include of "opt_compat.h" if it
wouldn't affect anything we create.  This will fix recent breakage
of the ibcs2 LKM.  The ibcs2 syscall files were not regenerated
properly, so the LKM didn't break immediately when we started
generating this extraneous include.

9ae58db7a3 Include "opt_compat.h" explicitly instead of depending on 
makesyscalls.sh generating it as pollution.

Don't attempt to separate the includes by newlines.  makesyscalls.sh
just ignores newlines.

afba897ff2 Fixed `make depend', which I broke here about a month ago by moving 
the null default for `depend' from bsd.dep.mk to bsd.obj.mk.
bsd.kmod.mk included these files in a bad order, so it picked up
the null default.

rename("D1/X/", "D2/Y/") gives a wrong link count for D2.
