Mostly adding DEBUG mode tracing (when appropriate verbose tracing
is enabled generally) whenever a shell (including sushell) process
exits, so shells that the tracing should indicate why ehslls that
vanish did that.
Note for future investigators: if the relevant tracing is enabled,
and a (sub-)shell still simply seems to have vanished without trace,
the likely cause is that it was killed by a signal - and of those,
the most common that occurs is SIGPIPE.
Use r10 instead; no need to preserve saipic_base, previous content of
r10, throughout this function, except for the case of INTR_DEBUG.
For INTR_DEBUG, load saipic_base to scratch register every time it
becomes necessary. This is no performance penalty compared with
subsequent printf() calls.
XXX
Rewrite this function by C. There seems no particular reason to
use assembler, and no major performance regression is expected.

Classify them as dropped like Linux does (FreeBSD just ignores them). From RVP.
Due to the rule, "sin" and "sin6" can be treated as restrict pointers.
Compilers seem to be confused by structure copy for those pointed by
them before assignments.
For aarch64eb, GCC 9 and 10 compile t_tcp.c rev 1.11 into a code, where
fetch for "sin6->sin6_port" is preceding the structure copy "ss = bs".
This results in failure of connect(2) with EADDRNOOTAVAIL.

NOTE:
SIOCGLAGGPORT is based on FreeBSD implementation.
And, currently, it is not used in NetBSD kernel/userland.
Make several comments more precise.
Rename process_end_of_file to process_eof to match the token name.
Change the order of assignments in analyze_comment to keep the com_ind
computations closer together.
In copy_comment_wrap, use pointer difference instead of pointer addition
to stay away from undefined behavior.
No functional change.
