lockdebug(9): Try to show symbol names if possible.

Also print the possible owner in ddb/crash `show lock' even if the
kernel is built without LOCKDEBUG.

Output may not be as pretty before with two neatly aligned columns,
but that can be changed; for now the value of having the symbols
printed instead of just obscure hex addresses (which one's an lwp
address and which one's a code pointer? can never remember!) should
outweigh the prettiness temporarily lost.

Use printf, not printf_nolog, in lockdebug dumps.

Otherwise we get no diagnostic information in crash dumps or dmesg,
which really puts a damper on the utility of lockdebug.

(If there's a reason for printf_nolog instead of printf, it should be
documented in comments here, and it had better be a pretty good
reason for destroying the diagnostic information that is half the
point of lockdebug.)

Introduce kcov_silence_enter() and kcov_silence_leave(), to allow to
temporarily disable KCOV on the current lwp. Should be used in the rare

uninteresting subsystem.

Use this capability to silence KCOV during the LOCKDEBUG lookups. This
divides the size of the KCOV output by more than two in my KCOV+vHCI
tests.

- Make this needed sequence always work for condvars, by not touching the CV
  again after wakeup.  Previously it could panic because cv_signal() could
  be called by cv_wait_sig() + others:

	cv_broadcast(cv);
	cv_destroy(cv);

- In support of the above, if an LWP doing a timed wait is awoken by
  cv_broadcast() or cv_signal(), don't return an error if the timer
  fires after the fact, i.e. either succeed or fail, not both.

- Remove LOCKDEBUG code for CVs which never worked properly and is of
  questionable use.

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.

this fixes ddb 'reboot' on softiron od1000.

call spl0() before cpu_reboot(), so that there's a chance that:
- interrupts can work afterwards
- this also means if IO stalls, serial break might work again.

this mimics how reboot(2) ends up calling cpu_reboot().

Resolve a couple of conflicts (result of the uimin/uimax changes)

Rename min/max -> uimin/uimax for better honesty.

These functions are defined on unsigned int.  The generic name
min/max should not silently truncate to 32 bits on 64-bit systems.
This is purely a name change -- no functional change intended.

HOWEVER!  Some subsystems have

	#define min(a, b)	((a) < (b) ? (a) : (b))
	#define max(a, b)	((a) > (b) ? (a) : (b))

even though our standard name for that is MIN/MAX.  Although these
may invite multiple evaluation bugs, these do _not_ cause integer
truncation.

To avoid `fixing' these cases, I first changed the name in libkern,
and then compile-tested every file where min/max occurred in order to
confirm that it failed -- and thus confirm that nothing shadowed
min/max -- before changing it.

I have left a handful of bootloaders that are too annoying to
compile-test, and some dead code:

cobalt ews4800mips hp300 hppa ia64 luna68k vax
acorn32/if_ie.c (not included in any kernels)
macppc/if_gm.c (superseded by gem(4))

It should be easy to fix the fallout once identified -- this way of
doing things fails safe, and the goal here, after all, is to _avoid_
silent integer truncations, not introduce them.

Maybe one day we can reintroduce min/max as type-generic things that
never silently truncate.  But we should avoid doing that for a while,
so that existing code has a chance to be detected by the compiler for
conversion to uimin/uimax without changing the semantics until we can
properly audit it all.  (Who knows, maybe in some cases integer
truncation is actually intended!)

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.

all of these paths include an assertion that the allocation has not failed,
so callers should not assert that again.

Fixes/improvements to RB-tree implementation:
1. Fix inverted node order, so that negative value from comparison operator
   would represent lower (left) node, and positive - higher (right) node.
2. Add an argument (i.e. "context"), passed to comparison operators.
3. Change rb_tree_insert_node() to return a node - either inserted one or
   already existing one.
4. Amend the interface to manipulate the actual object, instead of the
   rb_node (in a similar way as Patricia-tree interface does).
5. Update all RB-tree users accordingly.

XXX: Perhaps rename rb.h to rbtree.h, since cleaning-up..

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.

Merge scheduler changes from the vmlocking branch. All discussed on
tech-kern:

- Invert priority space so that zero is the lowest priority. Rearrange
  number and type of priority levels into bands. Add new bands like
  'kernel real time'.
- Ignore the priority level passed to tsleep. Compute priority for
  sleep dynamically.
- For SCHED_4BSD, make priority adjustment per-LWP, not per-process.
