(k5_debug_mutex_stats, k5_mutex_init_stats, k5_mutex_finish_init_stats,
K5_MUTEX_STATS_INIT): Add some dummy support for recording statistics on how
long mutexes are held, etc. Incomplete implementation started, but code not
enabled.
(k5_mutex_t): Add statistics field.
(K5_MUTEX_PARTIAL_INITIALIZER, k5_mutex_init_1, k5_mutex_init): Initialize it.

(k5_debug_loc): New type, may contain file/line info if DEBUG_THREADS_LOC is
defined.
(k5_os_nothread_*): Dummy implementation of mutex lock for a single-threded
process. Uses a flag and assert() if DEBUG_THREADS is defined, does nothing
interesting otherwise.
(k5_os_mutex*, k5_once*): General implementations, with dummy or POSIX or
POSIX-if-loaded-otherwise-dummy variants.
(k5_mutex_*): Combine OS-specific mutex implementation with optional file/line
tracking, and provide a place to instrument for other debugging or performance
data.

(k5_mutex_debug_finish_init, k5_mutex_debug_init, k5_mutex_debug_destroy): Save
current file and line.
(k5_mutex_debug_lock): Verify that the lock was unlocked before, and set the
state to locked.
(k5_mutex_debug_unlock): Verify that the mutex was locked before, and set the
state to unlocked.
(k5_debug_assert_locked, k5_debug_assert_unlocked): Use
k5_mutex_debug_check_init instead of checking initialized==1.

thread system isn't pthreads. (This is after the code disabling thread support
for non-pthreads systems, so it's a placeholder for now that should never get
invoked.)

one, and error out.
(We need weak reference support for pthread_once, gcc 2.95 doesn't
support them, but gcc 3, which has been out for nearly 3 years, does.)

execution. It won't be as useful in single-threaded programs for detecting
bugs in the mutex handling for now, though.
* k5-thread.h (k5_mutex_debug_check_init, k5_mutex_debug_update_loc): New
macros.
(k5_mutex_debug_lock, k5_mutex_debug_unlock): Use them.
(k5_mutex_lock, k5_mutex_unlock) [ENABLE_THREADS && DEBUG_THREADS]: Use them
instead of k5_mutex_debug_lock and k5_mutex_debug_unlock.
(enum k5_mutex_debug_states): New enum.
(K5_MUTEX_DEBUG_LOCKED, K5_MUTEX_DEBUG_UNLOCKED): Change to enumerator values.
(k5_mutex_debug_info): Use the enum type. Reorder fields.
(K5_MUTEX_DEBUG_INITIALIZER): Update for new field order.

that the initializer completed successfully. Delay initialization on POSIX
until the first "verification" call. Currently specific to a few platforms,
but should still build on others without thread support enabled.
Use it to finish creating (if necessary) and destroy mutexes, and free some
other storage "permanently" allocated by libraries (currently, libkrb5
cache/keytab type registries only). Change initialization of static mutexes to
a two-step operation, a static "partial" initializer and a "finish_init"
routine called from a thread-safe environment like library initialization is
assumed to be. POSIX will use the former, Windows will use the latter, and the
debug support will check that *both* have been used.
Added init/fini functions to com_err, profile, krb5, and gssapi libraries.
(The profile library one may need to be removed later.) The existing ones, not
thread-safe, are still around.
Use weak symbol support if available to figure out if the pthread library has
been linked in, and avoid calling certain routines if the C library stubs are
known not to exist or work.
Stub declarations for thread-specific data.
Minor bugfixes, whitespace changes.
