27d52f6943 OpenBSD's g_Ctoc() returned a false error when the target buffer was
exactly the right size.  Do it differently - pass a length rather than an
end-of-string+1 pointer as this is more convenient anyway.  Get rid of
the bogus +1's.

192846463a Rework the witness code to work with sx locks as well as mutexes.
- Introduce lock classes and lock objects.  Each lock class specifies a
  name and set of flags (or properties) shared by all locks of a given
  type.  Currently there are three lock classes: spin mutexes, sleep
  mutexes, and sx locks.  A lock object specifies properties of an
  additional lock along with a lock name and all of the extra stuff needed
  to make witness work with a given lock.  This abstract lock stuff is
  defined in sys/lock.h.  The lockmgr constants, types, and prototypes have
  been moved to sys/lockmgr.h.  For temporary backwards compatability,
  sys/lock.h includes sys/lockmgr.h.
- Replace proc->p_spinlocks with a per-CPU list, PCPU(spinlocks), of spin
  locks held.  By making this per-cpu, we do not have to jump through
  magic hoops to deal with sched_lock changing ownership during context
  switches.
- Replace proc->p_heldmtx, formerly a list of held sleep mutexes, with
  proc->p_sleeplocks, which is a list of held sleep locks including sleep
  mutexes and sx locks.
- Add helper macros for logging lock events via the KTR_LOCK KTR logging
  level so that the log messages are consistent.
- Add some new flags that can be passed to mtx_init():
  - MTX_NOWITNESS - specifies that this lock should be ignored by witness.
    This is used for the mutex that blocks a sx lock for example.
  - MTX_QUIET - this is not new, but you can pass this to mtx_init() now
    and no events will be logged for this lock, so that one doesn't have
    to change all the individual mtx_lock/unlock() operations.
- All lock objects maintain an initialized flag.  Use this flag to export
  a mtx_initialized() macro that can be safely called from drivers.  Also,
  we on longer walk the all_mtx list if MUTEX_DEBUG is defined as witness
  performs the corresponding checks using the initialized flag.
- The lock order reversal messages have been improved to output slightly
  more accurate file and line numbers.

c31146a14e - Resort some includes to deal with the new witness code coming in shortly.

6283b7d01b - Switch from using save/disable/restore_intr to using critical_enter/exit
and change the u_int mtx_saveintr member of struct mtx to a critical_t
  mtx_savecrit.
- On the alpha we no longer need a custom _get_spin_lock() macro to avoid
  an extra PAL call, so remove it.
- Partially fix using mutexes with WITNESS in modules.  Change all the
  _mtx_{un,}lock_{spin,}_flags() macros to accept explicit file and line
  parameters and rename them to use a prefix of two underscores.  Inside
  of kern_mutex.c, generate wrapper functions for
  _mtx_{un,}lock_{spin,}_flags() (only using a prefix of one underscore)
  that are called from modules.  The macros mtx_{un,}lock_{spin,}_flags()
  are mapped to the __mtx_* macros inside of the kernel to inline the
  usual case of mutex operations and map to the internal _mtx_* functions
  in the module case so that modules will use WITNESS and KTR logging if
  the kernel is compiled with support for it.

82da2f64b3 - Include <machine/prom.h> to get the prototype for prom_halt().
- If there is no gdb device, just return without trying to return any
  value since gdb_handle_exception() returns void.
- When calling prom_halt(), pass in a value telling it to actually halt
  and not to randomly choose whether or not to halt or reboot depending on
  whatever value happened to be in a0 when the call was made.

919eea6db9 Check whether we need to do a full restore after handling ASTs. If
an AST results in a signal being delivered, we'll need to do a full register
restore so as to properly setup the signal handler.  This is somewhat of
a pessimization, because ast() will be called twice in this case.

This fixes several problems that have been reported where signal intensive
userland apps (most notably dump) have been SEGV'ing for no fault of their
own.

Thanks to Peter Jeremy <peter.jeremy@alcatel.com.au> for presenting the
AST scenario which led to me fiinally figuring this out.

8de34b2541 Finally fix __yp_ping(). We can't use the old locally defined clntudp_call()
method anymore since the code inside the RPC library has changed too much.
Now that the clnt_dg module has the necessary code internally, we can yank
out the local method code and turn on the ASYNC hack with clnt_control().
This will make the -m flag work again.

65d3c627a5 Add a CLSET_ASYNC command, which allows us to (ab)use the clnt_dg transport
to make asynchronous RPCs. This is needed to help fix ypbind, which can no
longer override the clnt_dg_call() method (formerly the clntudp_call()
method) due to all the internal descriptor locking code in TI-RPC. Turning
on this flag allows us to send an RPC request, then return immediately,
and handle a reply later, rather than being forced to do the request
and reply in a single function call.

Also fix a byte ordering bug: when clnt_dg_call() increments the XID
prior to transmitting a request, it uses the raw value, which is wrong.
The XID is stored in network byte order, i.e. big-endian. The CLSET_XID
and CLGET_XID commands in clnt_dg_control() use ntohl()/htonl() to get
the byte ordering right, but because clnt_dg_call() does not do this,
using CLSET_XID/CLGET_XID doesn't actually work, unless you're on a
big endian host, which we aren't (yet). Fix clnt_dg_call() to byte swap
properly when doing the increment.
