/* IO locking rules:
UNIT_LOCK is a master lock, protecting UNIT_ROOT tree and UNIT_CACHE.
Concurrent use of different units should be supported, so
each unit has its own lock, LOCK.
Open should be atomic with its reopening of units and list_read.c
in several places needs find_unit another unit while holding stdin
unit's lock, so it must be possible to acquire UNIT_LOCK while holding
some unit's lock. Therefore to avoid deadlocks, it is forbidden
to acquire unit's private locks while holding UNIT_LOCK, except
for freshly created units (where no other thread can get at their
address yet) or when using just trylock rather than lock operation.
In addition to unit's private lock each unit has a WAITERS counter
and CLOSED flag. WAITERS counter must be either only
atomically incremented/decremented in all places (if atomic builtins
are supported), or protected by UNIT_LOCK in all places (otherwise).
CLOSED flag must be always protected by unit's LOCK.
After finding a unit in UNIT_CACHE or UNIT_ROOT with UNIT_LOCK held,
WAITERS must be incremented to avoid concurrent close from freeing
the unit between unlocking UNIT_LOCK and acquiring unit's LOCK.
Unit freeing is always done under UNIT_LOCK. If close_unit sees any
WAITERS, it doesn't free the unit but instead sets the CLOSED flag
and the thread that decrements WAITERS to zero while CLOSED flag is
set is responsible for freeing it (while holding UNIT_LOCK).
flush_all_units operation is iterating over the unit tree with
increasing UNIT_NUMBER while holding UNIT_LOCK and attempting to
flush each unit (and therefore needs the unit's LOCK held as well).
To avoid deadlocks, it just trylocks the LOCK and if unsuccessful,
remembers the current unit's UNIT_NUMBER, unlocks UNIT_LOCK, acquires
unit's LOCK and after flushing reacquires UNIT_LOCK and restarts with
the smallest UNIT_NUMBER above the last one flushed.
If find_unit/find_or_create_unit/find_file/get_unit routines return
non-NULL, the returned unit has its private lock locked and when the
caller is done with it, it must call either unlock_unit or close_unit
on it. unlock_unit or close_unit must be always called only with the
private lock held. */

(extract_int, extract_uint, extract_real): Adjust internal_error callers. * runtime/fpu.c (_GNU_SOURCE): Don't define here. * runtime/error.c: Include ../io/unix.h. (filename, line): Remove variables. (st_printf): Pass address of a local variable to init_error_stream. (show_locus): Add cmp argument. Use fields it points to rather than filename and line variables. (os_error, runtime_error): Remove show_locus calls. (internal_error): Add cmp argument. Pass it down to show_locus. (generate_error): Likewise. Use flags bitmask instead of non-NULL check for iostat and iomsg parameter presence, adjust for st_* calling convention changes. * runtime/stop.c (stop_numeric, stop_string): Remove show_locus calls. * runtime/pause.c (pause_numeric, pause_string): Likewise. * runtime/string.c: Include ../io/io.h. (find_option): Add cmp argument. Pass it down to generate_error. * intrinsics/flush.c (recursive_flush): Remove. (flush_i4, flush_i8): Use flush_all_units. Add unlock_unit call. * intrinsics/rand.c: Include ../io/io.h. (rand_seed_lock): New variable. (srand, irand): Add locking. (init): New constructor function. * intrinsics/random.c: Include ../io/io.h. (random_lock): New variable. (random_r4, random_r8, arandom_r4, arandom_r8): Add locking. (random_seed): Likewise. open failed if fd < 0. Set i correctly. (init): New constructor function. * intrinsics/system_clock.c (tp0, t0): Remove. (system_clock_4, system_clock_8): Don't subtract tp0/t0 from current time, use just integer arithmetics. * intrinsics/tty.c (isatty_l4, isatty_l8, ttynam_sub): Add unlock_unit calls.
