mutex(9): Convert to membar_acquire/release.

Except for setting the waiters bit -- not sure if this is actually
required to be store-before-load/store.  Seems unlikely -- surely
we'd have seen some serious bug by now if not, because membar_enter
has failed to guarantee that on x86! -- but I'm leaving it for now
until I have time to think enough about it to be sure one way or
another.

- In kern_mutex.c, if MUTEX_CAS() is not defined, define it in terms of
  atomic_cas_ulong().
- For arm, ia64, m68k, mips, or1k, riscv, vax: don't define our own
  MUTEX_CAS(), as they either use atomic_cas_ulong() or equivalent
  (atomic_cas_uint() on m68k).
- For alpha and sparc64, don't define MUTEX_CAS() in terms of their own
  _lock_cas(), which has its own memory barriers; the call sites in
  kern_mutex.c already have the appropriate memory barrier calls.  Thus,
  alpha and sparc64 can use default definition.
- For sh3, don't define MUTEX_CAS() in terms of its own _lock_cas();
  atomic_cas_ulong() is strong-aliased to _lock_cas(), therefore defining
  our own MUTEX_CAS() is redundant.

Fix an IPI deadlock scenario that resulted in a TLB shootdown timeout
panic reported by John Klos on port-alpha:

- pmap_tlb_shootnow(): If we acquire a pmap's activation lock, we will
  have raised the IPL on the current CPU to IPL_SCHED until we drop
  the tlb_lock (due to how nested spin mutexes work).  As such, when
  we release the activation lock, forcibly lower our IPL back to IPL_VM
  so that we can receive and process IPIs while waiting for other CPUs
  to process the shootdowns.
- mutex_vector_enter(): Invoke SPINLOCK_SPIN_HOOK while spinning to acquire
  a spin mutex.  This is a nop on most platforms, but it's important on
  the Alpha.  Without this, IPIs (and thus TLB shootdowns) cannot be
  processed if trying to acquire an IPL_SCHED spin mutex such as those
  used by the scheduler.

...and while we're poking around in here:

- Rework the Alpha SPINLOCK_SPIN_HOOK to only check curcpu()->ci_ipis
  if the current CPU's IPL is >= IPL_CLOCK (thus ensuring that preemption
  is disabled and thus guaranteeing that curcpu() is stable).  (Alpha does
  not yet support kernel preemption, but this is now one less thing that
  would need to be fixed.)

Avoid prepending a timestamp to lock debug outputs on ddb

Lock printer functions (lockops_t#lo_dump) use printf_nolog to print, but
printf_nolog now prepends a timestamp which is unnecessary for ddb:

    db{0}> show all locks/t
    [Locks tracked through LWPs]
    Locks held by an LWP (iperf):
    Lock 0 (initialized at soinit)
    lock address : 0xffffedeb84b06080 type     :     sleep/adaptive
    initialized  : 0xffffffff806d8c3f
    shared holds :                  0 exclusive:                  1
    shares wanted:                  0 exclusive:                 11
    current cpu  :                  0 last held:                  1
    current lwp  : 0xffffedeb849ff040 last held: 0xffffedeb7dfdb240
    last locked* : 0xffffffff806d8335 unlocked : 0xffffffff806d8385
    [ 79103.0868574] owner field  : 0xffffedeb7dfdb240 wait/spin:                1/0

Fix it by passing a printer function to lo_dump functions, i.e., make the
functions use db_printf on ddb.

Obtain proper initialized addresses of locks allocated by mutex_obj_alloc or rw_obj_alloc

Initialized addresses of locks allocated by mutex_obj_alloc or rw_obj_alloc
were not useful because the addresses were mutex_obj_alloc or rw_obj_alloc
itself. What we want to know are callers of them.

Spinkle ASSERT_SLEEPABLE to xcall functions

Use db_printf instead of printf in ddb

Add a new command, show lockstat, which shows statistics of locks
Currently the command shows the number of allocated locks.
The command is useful only if LOCKDEBUG is enabled.

Add a new command, show all locks, which shows information of active locks

The command shows information of all active (i.e., being held) locks that are
tracked through either of LWPs or CPUs by the LOCKDEBUG facility.  The /t
modifier additionally shows a backtrace for each LWP additionally.  This
feature is useful for debugging especially to analyze deadlocks.
The command is useful only if LOCKDEBUG is enabled.

Don't pass a unset address to lockdebug_lock_print

x86: avoid accessing invalid addresses in ddb like arm32
This avoids that a command stops in the middle of an execution if
a fault occurs due to an access to an invalid address.

Get rid of a redundant output

Improve wording. Fix a Cm argument.

ddb: rename "show lockstat" to "show lockstats" to avoid conflicting with lockstat(8)

Distinguish spin mutex and adaptive mutex on rump kernels for LOCKDEBUG
Formerly rump kernels treated the two types of mutexes as both adaptive for
LOCKDEBUG for some reasons.
Now we can detect violations of mutex restrictions on rump kernels such as
taking an adaptive mutex with holding a spin mutex as well as normal kernels.
--
rump: check if the mutex is surely owned by the caller in mutex_exit
Unlocking a not-owned mutex wasn't detected well (it could detect if the mutex
is not held by anyone but that's not enough). Let's check it (the check is the
same as normal kernel's mutex).
If LOCKDEBUG is enabled, give the check over LOCKDEBUG because it can provide
better debugging information.

      This will help my fellow developers spot "use before initialised" problems
      that hppa picks up very well.

It has to be done differently, because the semantics of mtx_owner in the non-
LOCKDEBUG case can vary significantly between archs, and thus it is not
possible to simply flip a bit to 1.

Ok core@, as at least i386 is unbootable right now.

Disable generating an upcall for blocking on an adaptive mutex. While
we are indeed blocking, there really is no way for the app to take
advantage of this. We could, for instance, be sleeping on p_lock!

LOCKDEBUG:

- Tweak it so it can also catch common errors with condition variables.
  The change to kern_condvar.c is not included in this commit and will
  come later.

- Don't call kmem_alloc() if operating in interrupt context, just fail
  the allocation and disable debugging for the object. Makes it safe
  to do mutex_init/rw_init/cv_init in interrupt context, when running
  a LOCKDEBUG kernel.

- Ensure that LWPs going to sleep are on the sleep queue before releasing

- Assume that LWPs blocked on a turnstile will never be swapped out.
- LWPs blocking on a turnstile must have kernel priority, as they
  are consuming kernel resources.

- Blocking in order to avoid deadlocking against the kernel_lock turns
  out to be not so good, since it puts a lot of back pressure onto other
  locks. Instead, just drop kernel_lock and re-acquire it when returning
  from mutex_vector_exit. In the LOCKDEBUG case, continue to block as it
  helps to expose locking bugs.
- Allow NODEBUG mutexes to be spin mutexes, also. To be revisited.

Add some minimal mutex debugging infrastructure.
* struct mutex_debug_info, which MD code adds to the kmutex_t
  when MUTEX_DEBUG is defined, contains the PC values of the
  last-locked and last-unlocked.
* MD code is expected to set last-locked in the enter fast path.
* MD code is expected to always call mutex_vector_exit() in the
  exit case.

Note: this code relies on MD code performing a tail-call to the
slow-path.

Add a "nextproc" argument to turnstile_wakeup() to selectively
wake up a single thread.  This will allow us to implement direct
handoff of rwlocks.

New kernel mutex implementation, modeled after those found in Solaris
and described in:

	Solaris Internals: Core Kernel Architecture, Jim Mauro and
	    Richard McDougall, section 3.5.

Both adaptive (spin/sleep) and spin (spin + block interrupts) mutexes
are implemented.  See <sys/mutex.h> for the support that machine-dependent
code must supply.
