- 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.

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.

As jhb noted, the actual mmap(2) implementation is under sys/vm, not
sys/kern/, so the correct logical place is tests/sys/vm/, not
tests/sys/kern/

Change {atf,plain,tap}.test.mk to be internal implementation details of
bsd.test.mk. Makefiles that build tests should now only include bsd.test.mk
and declaratively specify what they want to build, without worrying about
the internal implementation of the mk files.
The reason for this change is to permit building test programs of different
interfaces from a single directory, which is something I had a need for
while porting tests over from src/tools/regression/.
Additionally, this change makes it possible to perform some other requested
changes to bsd.test.mk in an easier manner. Coming soon.
Set WARNS=5 for all files in this directory

Fix compiler warnings. Most were benign, but rcvbuf_oversized
wasn't working as intended because I forgot to set the buffer sizes.

It's coverage is a superset of the old tests and it uses ATF. It
includes test cases for bugs kern/185813 and kern/185812.
