Document TRAP_SCE and TRAP_SCX in siginfo(2)

branches: 1.22.12;
Add new si_code TRAP_DBREG

It replaces previous TRAP_HWWPT and is designed to be used for debug
register traps (both watchpoints and breakpoints).

TRAP_HWWPT wasn't documented in siginfo(2) neither noted in doc/CHANGES -
- document it and add new entry in CHANGES. This move is a step towards
switch the watchpoint ptrace(2) api to PT_*DBREGS.

This code was introduced recently and has no impact on stable releases.

Document TRAP_LWP in siginfo(2)

TRAP_LWP - process lwp (thread) traps

Document TRAP_CHLD in siginfo(2)

The SIGTRAP signal is thrown from the kernel if EVENT_MASK (ptrace_event)
enables PTRACE_FORK. This new si_code helps debuggers to distinguish the
exact source of signal delivered for a debugger.

Another purpose of TRAP_CHLD is to retain the same behavior inside the
NetBSD kernel for process child traps and have an interface to monitor it.

Retrieving exact event and extended properties of process child trap is
available with PT_GET_PROCESS_STATE.

There is no behavior change for existing software.

This si_code value is NetBSD extension.

Sort a bit.

Document that TRAP_EXEC is .Nx extension and update .Sh HISTORY for it

Document TRAP_EXEC in SIGRAP in siginfo(2)

TRAP_EXEC - Process exec trap

This signal is emitted on exec() when a process is controlled by a
debugger.

Bump date for siginfo(2) and document SI_LWP and SI_NOINFO as .Nx extension

Document SI_MESGQ in siginfo(2)

SI_MESGQ
The signal was generated because of the arrival of a message
on an empty message queue.

This code was commented out since inception of this manual page (originally
located in siginfo(5)).

SI_QUEUE
The signal was generated via sigqueue(2).

Document SI_NOINFO in siginfo(2)

SI_NOINFO
The signal was generated without specifc info available.

Rename SIGPOLL signal to SIGIO in documentation siginfo(2)

SIGPOLL is absent on NetBSD, it's emulated in linux_compat(8).

branches: 1.9.2;
I do like the idea of April 43, 2016, but it's just not standardized enough.

Fix description of si_status.

Fix some typos and make style more consistent.

branches: 1.6.10;
Note that si_addr may be inaccurate on certain architectures.

Example: i386/amd64 alignement fault can drive to SIGBUS (when configured
so by process), however the faulty address returned by the CPU is not
reliable.

Bump date.

branches: 1.5.6; 1.5.8;
fix typo.

Convert TNF licenses to new 2 clause variant

branches: 1.3.10; 1.3.12;
rename si_sigval -> si_value.

.Nm siginfo_t -> .Nm siginfo

Makes the manual page name match the whatis database.

Move siginfo(5) and ucontext(5) to siginfo(2) and ucontext(2) resp.,

INTRV is INT-RV - integer return value (not INTR-V, interrupt vector) :)

Use tagged list.

Flags are .Fl not .Ar

Document _UC_MACHINE_*() in ucontext(2)

Document:
- _UC_MACHINE_SP()
- _UC_MACHINE_FP()
- _UC_MACHINE_PC()
- _UC_MACHINE_INTRV()
- _UC_MACHINE_SET_PC()

Document fragileness of the frame-pointer accessor.

Properly mark the standard that "deprecated" all of these.

Note that the ucontext(2) et. al. were first moved from X/OPEN extensions to
the base POSIX-2001 and later marked as obsolete in POSIX-2008.

Improvements to markup.
