Enhance pipe(2)-based IPC barrier in attach5 of t_ptrace_wait

The write(2) call does not block and there is need to perform handshake, in
order to wait on the read(2) call.

The pipe(2) interface for IPC purposes is quite difficult to design and get
right. It might be refactored and with added new helper functions, although
it would be better to switch to some other mechanism rather. But as it
works now quite well in the current set of tests, do not touch it.

Assert that tracer parent can PT_ATTACH to its child.
This test is for all members of the wait(2) family.

Currently it is marked as an explicit failure PR kern/51621.

I faced the following issues (noted and discussed in the bug report):

- PT_ATTACH seems to work, but waiting for stopped status and signal from the
  child results in getting SIGTRAP, not SIGSTOP like in Linux and FreeBSD. This
  might be by design, I'm unsure. However, so far I was getting SIGSTOP from a
  tracer process that was not the parent. SIGSTOP vs SIGTRAP logic also
  complicates the things up as tracer must check whether is a parent for tracee
  or not - this shouldn't be needed.

- PT_CONTINUE seems to have no effect at all, the child hangs. This operation
  works on Linux and FreeBSD and in the end, test passes correctly.

- Debugging this with gdb(1) results in receiving SIGABRT from the GNU
  debugger (in the moment of raising/receiving SIGTRAP). This is making the
  things harder in general.

Tidy up in6_select*

This change tidies up in6_select* functions, especially
selectroute.

selectroute is annoying because:
- It returns both/either of a rtentry and/or an ifp
  - Yes, it may return only an ifp!
    - It is valid but selectroute shouldn't handle the case
  - Such conditional behavior makes it difficult
    to apply locking/psref thingy
- It may return a rtentry even if error
- It may use opt->ip6po_nextroute rtcache implicitly
  - The caller can know if it is used
    by rtcache_validate(&opt->ip6po_nextroute)
    but it's racy in MP-safe world
  - Even if it uses opt->ip6po_nextroute, it may
    return a rtentry that isn't derived from the rtcache

The change includes:
- Rename selectroute to in6_selectroute
  - Let a remaining caller of selectroute, in6_selectif,
    use in6_selectroute instead
- Let in6_selectroute return only an rtentry
  - If error, it doesn't return an rtentry
  - A caller gets an ifp from a returned rtentry
- Allow in6_selectroute to modify a passed rtcache
  and a caller can know if opt->ip6po_nextroute is
  used via the rtcache
- Let callers (ip6_output and in6_selectif) handle
  the case that only an ifp is required

Fix a breakout of loops

As the comment "find first available ipv4 address" indicates,
if an IP address is found, we need to leave the two nested loops,
a loop for an interface list and a loop for IP addresses of
an interface. However, the original code broke away only from
the inner loop.

The original (wrong) behavior was non-critical, which just
returned a non-first IP address. Unfortunately, after applying
psref, the behavior may call psref_acquire twice to a target
with the same psref object, resulting in a kernel panic eventually.

Add new tests:
- waitpid_options

- wait3_options

These tests are included in t_wait_noproc and t_wait_noproc_wnohang.

waitpid_options, wait3_options, wait4_options test combinations of options
of: bit for WALLSIG, WALTSIG, __WALL, __WCLONE and later a full combination
mask of WNOWAIT, WEXITED, WUNTRACED, WSTOPPED, WTRAPPED and WCONTINUED.

waitid and wait6 test full combination mask of WNOWAIT, WEXITED, WUNTRACED,
WSTOPPED, WTRAPPED and WCONTINUED -- excluded empty value and singular
WNOWAIT.

For compatibility reasons alter waitid and wait6 to test against options
WEXITED | WTRAPPED, as it's equivalent to waitpid, wait3, wait4.

The intention for these tests it to catch any possible issues with slighty
changed behavior of wait(2)-like functions in terms of valid options
values.

All tests pass successfully.

Revert 1.264 - that was intended to fix 51600, but didn't, it just
hid the problem, and caused 51606.  This fixes 51606.

Handle waiting on a process that has been detatched from its parent
because of being ptrace'd by some other process.  This fixes 51600.
("handle" here means that the wait() hangs, or with WNOHANG, returns 0,
we cannot actually wait on a process that is not currently an attached
child.)

Note: the detatched process waiting is not yet perfect (it fails to
take account of options like WALLSIG and WALTSIG) - suport for those
(that is, ignoring a detatched child that one of those options will
later cause to be ignored when the process is re-attached.)

For now, for ither than when waiting for a specific process ID, when
a process does a wait() sys call (any of them), has no applicable
children attached that can be returned, and has at least one detatched
child, then we do a linear search of all processes to look for a
suitable detatched child.  This is likely to be slow - but very rare.
Eventually it might be better to keep a list of detatched children
per process.

Add new tests for combination of wait(2) interfaces with ptrace(2)

Move out wait(2) specific tests from t_ptrace and put them to t_ptrace_wait

Add generic code fragments to reuse the same source-code for every member
of the wait(2) family, namely:
- wait(2)

Currently in the new test-suite there are the following tests:
- traceme1
- traceme2
- traceme3
- traceme4
- attach1

Not all tests are possible to be executed against every wait(2)-like
interface, therefore they will be disabled in such case. Currently this
limits attach1 to waitpid(2), waitid(2), wait4(2), wait6(2), while the
other tests (traceme 1-4) run with all of the interfaces.

The construct of this file is dedicated for addition of new tests in the
close future.

As of now all of the tests pass correctly.

Add new tests: tests/lib/libc/sys/t_wait_noproc and t_wait_noproc_wnohang

The t_wait_noproc test checks whether wait(2)-family of functions return
error and set ECHILD for lack of childs.

The t_wait_noproc_wnohang adds to options (except wait(2), wait3(2)) new
parameter WNOHANG and verifies that error is still signaled and errno set
to ECHILD.

Currently t_wait_noproc_wnohang reports failures, these have been marked as
expected and referenced to PR standards/51606.

Reduce the scope of the softc lock further and track device state via
sc_state.

All ucom methods apart from ucom_{read,write} are called without the
softc lock held.

ucom_close is called on last close only to match ucom_open being called
on first open only.

Fix ucom_detach where refcnt wasn't being decremented.

More DEBUG.

XXX still not sure where tty_lock needs to be held.

Since the stopped bits set is a subset of the continued bits set, check
that we are not continued in WIFSTOPPED.
Make WIFSIGNALED more obvious, it being the remaining state of not exited,
not stopped and not continued.

Move if_43.c back into the shared Makefile.sysio where it really
belongs.

Update the code to invoke the two routines compat_cvtcmd() and
compat_ifioctl() through indirect pointers.  Initialize those
pointers in sys/net/if.c and update them in the compat module's
initialization code.

Actually, this problem won't be reported upstream, their code is
just ...

ptrdiff_t nitems_max = PTRDIFF_MAX - WORK_AROUND_QTBUG_53071;
ptrdiff_t amax = nitems_max < SIZE_MAX ? nitems_max : SIZE_MAX;

which is just fine if you think about it a little,  Unfortunately,
in our zealous effort to never leave a ggc warning unused, and to
treat all of the warnings as fatal errors, that code falls foul of the
"you must not compare an unsigned value with a signed value" warning.

nitems_max is a (signed) largish positive integer (obviously, by
inspection).  If it is less than SIZE_MAX then amax is just nitems_max.
In the unlikely case that size_t has less bits than ptrdiff_t so
SIZE_MAX is smaller, amax is limited to SIZE_MAX (which in that case
is known to fit in the ptrdiff_t and to remain positive).

To pacify gcc (and the way the build system uses it), casts are
required.  Unfortunately the cast that was installed here was to
convert SIZE_MAX to a ptrdiff_t.  Unfortunately when ptrdiff_t has
the same number of bits (or less) as size_t (ie: the common case)
but is signed, (ptrdiff_t)SIZE_MAX is just a fancy way of writing -1.

Rearrange the casting in a way that keeps the original intent
of the code for us (it is actyaly now incorrect if size_t has less
bits than a ptrdiff_t) and keeps gcc happy, all at the same time.

What a mess.

Revert a couple of lines of code from tzcode2016i to their state in 2016h

SIZE_MAX is the max value of a size_t (and is unsigned) so when converted
to a ptrdiff_t  (int) becomes -1.  That's not what the code was attempting
to achieve.

This will be reported upstream to the tzcode maintainers, and we'll see
what variation appears in tzcode2016j ...

Until then, the older code always worked for us, so it will do for now.

This should fix the broken i386 build.

Add new test wait6_stopgo_loop in t_wait

This test verifies that it is possible to emit multiple times SIGSTOP and
SIGCONT for a child.

Add checks that status does not return more than one valid state from the
following list: STOPPED, CONTINUED, EXITED and SIGNALED. This check fails
for WIFCONTINUED()==true as it currently and wrongly returns true for
WIFSTOPPED().

This verification is added to wait6_stopgo_loop and wait6_stop_and_go and
marked as expected failure and linked with PR standards/51603.

Remove trailing whitespace.
