Thomas König 3fe1910509 Use au->lock exclusively for locking in async I/O.
2020-02-18  Thomas Koenig  <tkoenig@gcc.gnu.org>

	PR fortran/93599
	* io/async.c (destroy_adv_cond): Do not destroy lock.
	(async_io): Make sure au->lock is locked for finishing of thread.
	Do not lock/unlock around signalling emptysignal. Unlock au->lock
	before return.
	(init_adv_cond): Do not initialize lock.
	(enqueue_transfer): Unlock after signal.
	(enqueue_done_id): Likewise.
	(enqueue_done): Likewise.
	(enqueue_close): Likewise.
	(enqueue_data_transfer): Likewise.
	(async_wait_id): Do not lock/unlock around signalling au->work.
	(async_wait): Unlock after signal.
	* io/async.h (SIGNAL): Add comment about needed au->lock.
	Remove locking/unlocking of advcond->lock.
	(WAIT_SIGNAL_MUTEX): Add comment. Remove locking/unlocking of
	advcond->lock.  Unlock mutex only at the end.  Loop on
	__ghread_cond_wait returning zero.
	(REVOKE_SIGNAL): Add comment. Remove locking/unlocking of
	advcond->lock.
	(struct adv_cond): Remove mutex from struct.

* io/format.c (parse_format_list): Implement the E0 exponent
width to provide smallest possible width for exponent fields.
Refactor code for correct parsing and better readability of the
code.

to access both the decimal precision and exponent widths used in
build_float_string.
* io/write_float.def (build_float_string): Use the passed in
exponent width to calculate the used width in the case of E0.
