sound: Fix lock order reversal in dsp_poll()
chn_poll() may hold both rdch and wrch channel locks while calling
chn_trigger(rdch). chn_trigger() switches the lock order from
"channel -> dsp dev" to "dsp dev -> channel" by temporarily dropping
the channel lock before acquiring the dsp lock.
However, only rdch was unlocked during the transition while wrch
remained locked. Since wrch is also a channel lock and witness had
already established the lock order requirement:
dsp dev -> channel
witness reports a lock order reversal when pcm_lock() is acquired while
wrch is still held.
Avoid holding rdch and wrch simultaneously during chn_trigger()
lock-order switching by only keeping the channel locks when needed.

lang/gcc16: Add port
GCC, the GNU Compiler Collection, supports a number of languages.
This port installs the C, C++, and Fortran front ends as gcc16,
g++16, and gfortran16, respectively.
This is the first release from the GCC 16 series.
It largely is a copy of lang/gcc16-devel, with release-specific
modifications from lang/gcc15.
Common issues that could happen when porting code to GCC 16:
