first. This is necessary to avoid warnings with -fshort-enums. Casting
to an int really should be enough, but turns out not to be.
This change will be documented in doc/HACKS.

- Fix a bug in ns_parserr(), where it was returning the wrong sort
of result code in some cases.
This is required to allow some -fshort-enums warnings to be fixed.
- Fix a bug in is_identifier(), where it was checking against EOF
instead of the END_OF_FILE token.
This is required to eliminate a warning with -fshort-enums.
sys_swapctl(SWAP_STATS). This enable the use of a kernel based
buffer instead of using some temporary memory in the stackgap,
whereas we cannot make sure that the size os the struct swapent array
will fit in it. (it is not known at build time, but the stackgap len
is set at build time).
initialization to it from uaudio_chan_set_param(). uaudio_set_params()
calls uaudio_chan_init().
These are required because bytes_per_frame is used in
uaudio_round_blocksize(), which is called before uaudio_set_params().
Noise of 4ch playing disappears by this change. 6ch playing still has
cyclic noise.
while setting up a child process. This prevents the major sources of
list inconsistencies that may result from doing list manipulations
from a signal handler.
XXX - all Lst_*() operations are at risk; look for ways to avoid touching
so much global state from the signal handlers.
- don't block the signal we're about to send to ourselves to
take the default action for
- restore the signal handler for the current signal
- remove duplicate sigprocmask() call
As a result, restoring the SIGTSTP handler in JobContinueSig() is no longer
necessary.
uvm_swap_stats(). This is done in order to allow COMPAT_* swapctl()
emulation to use it directly without going through sys_swapctl().
The problem with using sys_swapctl() there is that it involves
copying the swapent array to the stackgap, and this array's size
is not known at build time. Hence it would not be possible to
ensure it would fit in the stackgap in any case.
