Belatedly catch up with kern_sig.c rev 1.358:
Provide syscall information with SIGTRAP TRAP_SCE/TRAP_SCX so that
picotrace/truss, for example, works fine on COMPAT_NETBSD32.
With some minor changes:
- Centralize netbsd32_si{,32}_si{32,}() into netbsd32_ksi{,32}_ksi{32,}().
- Provide si_status with SIGCHLD.
- Remove the remaining of SA.

Sort by signal numbers as far as possible, adjust locations of functions.
No functional changes intended.

Provide _ptrace_state for SIGTRAP with TRAP_EXEC, TRAP_CHLD, or TRAP_LWP.

When converting siginfo, examine si_code at the beginning,
as explained in siginfo(2).
- If it is SI_NOINFO, there's no additional information.
- If it is non-positive, i.e., codes described in siginfo(2),
   we need to fill in _rt.

XXX
Description for SA_ASYNCIO in siginfo(2) seems outdated;
neither si_fd nor si_band are filled in with that code.

TRAP_EXEC does not have extra fields to be filled in at the moment.
Explicitly ignore fields for now.
