Move MAX_CPUS constant to cpu.h
When restoring a process' ipl, invoke setipl() on behalf on the kernel stack,
rather than on the process stack.
More include files cleaning:
- move MAX_CPUS constant to <machine/cpu.h>
- do not include <machine/board.h> unless needed. In fact, remove this file
  entirely on mvme88k, and include <machine/mvme*.h> on a
  compiling-for-this-board basis
- keep MAX_CMMUS constant private to the m8820x code
Missed one <machine/board.h>
Reuse first component of @newdepends, @libdepends to contain
a PKG_PATH (easy backward compatibility: is there a slash ?)

That's missing info to enable pkg_add to launch package building
in the ports tree as an alternate source of binary packages.
@man type file for manpages.
Initialize timeouts correctly, match isa com; fixes panics in
PR #3732 and #3881 (although more issues remain).
Forgot to add "anounce default-route" here. OK henning@
Allocate a dynamic buffer for sorting.  This way, we don't bork anymore
on directories with huge sets of files, and fix a bug while we're at it.
When sorting failed, the files that had been removed from the list didn't
get pushed back in it.
Better Z8536 initial programming.
Fun with the BUG:
- add the board's suffix to the machine description if there is one;
- recognize BUG version < 5 on MVME188, which don't provide a CNFG block.
in this case we'll assume 20MHz for now, until we can parse the ENV data block
correctly...
Missed to add virtual.c here. Noted by Benjamin Pineau.
Do not expire unestablished phase 2 SAs on SIGHUP.

Unused variables
Compile the RCS code into the cvs daemon for later use
* copy most of the code from cvs_resp_handle() into cvs_req_handle()
  and add some protection for unimplemented handlers
* add a bogus handler for the `Template' response, which we'll handle
  soon
No need to make __savectx visible and 8-byte aligned.
* add the appropriate preprocessor wrappers to compile only the code
  required for each program
* make cvs_sock_connect() take a full path to the socket
* no locks for now
* wrap more code between program-dependent ifdef's and fix a bug while
  we're at it
