Integrate tools/regression/pipe in to the FreeBSD test suite as
tests/sys/kern/pipe

- Fix style(9) bugs
- Fix compiler warnings
- Use `nitems(x)` instead of `sizeof(x) / sizeof(*x)` pattern

The testcases will be converted over to ATF eventually, but for now will be
integrated in as plain C tests

MFC 287386,288949,288993:
Export current system call code and argument count for system call entry
and exit events. To preserve the ABI, the new fields are moved to the
end of struct thread in these branches (unlike HEAD) and explicitly copied
when new threads are created. In addition, the new tests are only added
in 10.

r287386:
Export current system call code and argument count for system call entry
and exit events. procfs stop events for system call tracing report these
values (argument count for system call entry and code for system call exit),
but ptrace() does not provide this information. (Note that while the system
call code can be determined in an ABI-specific manner during system call
entry, it is not generally available during system call exit.)

The values are exported via new fields at the end of struct ptrace_lwpinfo
available via PT_LWPINFO.

r288949:
Fix various edge cases related to system call tracing.
- Always set td_dbg_sc_* when P_TRACED is set on system call entry
even if the debugger is not tracing system call entries. This
ensures the fields are valid when reporting other stops that
occur at system call boundaries such as for PT_FOLLOW_FORKS or
when only tracing system call exits.
- Set TDB_SCX when reporting the stop for a new child process in
fork_return(). This causes the event to be reported as a system
call exit.
- Report a system call exit event in fork_return() for new threads in
a traced process.
- Copy td_dbg_sc_* to new threads instead of zeroing. This ensures
that td_dbg_sc_code in particular will report the system call that
created the new thread or process when it reports a system call
exit event in fork_return().
- Add new ptrace tests to verify that new child processes and threads
report system call exit events with a valid pl_syscall_code via
PT_LWPINFO.

r288993:
Document the recently added pl_syscall_* fields in struct ptrace_lwpinfo.

MFC 283281,283282,283562,283647,283836,284000,286158:
Various fixes to orphan handling which also fix issues with following
forks.

283281:
Always set p_oppid when attaching to an existing process via procfs
tracing. This matches the behavior of ptrace(PT_ATTACH). Also,
the procfs detach request assumes p_oppid is always set.

283282:
Only reparent a traced process to its old parent if the tracing process is
not the old parent. Otherwise, proc_reap() will leave the zombie in place
resulting in the process' status being returned twice to its parent.

Add test cases for PT_TRACE_ME and PT_ATTACH which are fixed by
this change.

283562:
Do not allow a process to reap an orphan (a child currently being
traced by another process such as a debugger). The parent process does
need to check for matching orphan pids to avoid returning ECHILD if an
orphan has exited, but it should not return the exited status for the
child until after the debugger has detached from the orphan process
either explicitly or implicitly via wait().

Add two tests for for this case: one where the debugger is the direct
child (thus the parent has a non-empty children list) and one where
the debugger is not a direct child (so the only "child" of the parent
is the orphan).

283647:
Tweak the description of when waitpid() doesn't return any status for a
non-blocking wait to avoid the word "empty".

283836:
Consistently only use one end of the pipe in the parent and debugger
processes and do not rely on EOF due to a close() in the debugger.

284000:
Add a CHILD_REQUIRE macro similar to ATF_REQUIRE for use in child processes
of the main test process.

286158:
Clear P_TRACED before reparenting a detached process back to its
original parent. Otherwise the debugee will be set as an orphan of
the debugger.

Add tests for tracing forks via PT_FOLLOW_FORK.

MFC refactoring of the *.test.mk files.

- r263161 Make bsd.test.mk the only public mk fragment for the building of tests.
- r263172 Move FreeBSD Test Suite-specific code to a suite.test.mk file.
- r263204 Add some documentation for bsd.test.mk.
- r263217 Document support for TAP-compliant Perl test programs.

This is "make tinderbox" clean.

use TESTS_SUBDIRS for kern instead of SUBDIRS. I don't
think it makes a difference in this case, but
TESTS_SUBDIRS is generally correct for subdirectories
that contain tests.
