kamil 4f79a48470 Introduce PT_LWPSTATUS + PT_LWPNEXT, obsolete PT_LWPINFO 
PT_LWPINFO is a legacy ptrace(2) operation that was originally intended
to retrieve the thread (LWP) information inside a traced process.

It has a number of flaws and is confused with PT_LWPINFO from FreeBSD.

PT_LWPSTATUS and PT_LWPNEXT address the problems (shortly by: rename,
removal of pl_event) and introduces new features: signal context
(pl_sigpend, pl_sigmask), LWP name (pl_name), LWP TLS base address
(pl_private). The private pointer was so far missing information for
a debugger.

PT_LWPSTATUS@nnn is now shipped with core(5) files and contain LWP specific
information, so far missed in the core(5) files.

PT_LWPSTATUS retrieves LWP information for the prompted thread.
PT_LWPNEXT retrieves LWP information for the next thread, borrowing the
semantics from NetBSD specific PT_LWPINFO.

PT_LWPINFO is namespaced with __LEGACY_PT_LWPINFO and still available for
the foreseeable future, without plans of removing it.

Add ATF tests for PT_LWPSTATUS + PT_LWPNEXT.

Keep ATF tests for PT_LWPINFO.

Switch GDB to new API.

Proposed on tech-kern@.
