Fix known issues which blow up the process after dlopen("libthr.so") (or loading a dso linked to libthr.so into process which was not linked against threading library).
- Remove libthr interposers of the libc functions, including __error(). Instead, functions calls are indirected through the interposing table, similar to how pthread stubs in libc are already done. Libc by default points either to syscall trampolines or to existing libc implementations. On libthr load, libthr rewrites the pointers to the cancellable implementations already in libthr. The interposition table is separate from pthreads stubs indirection table to not pull pthreads stubs into static binaries.
- Postpone the malloc(3) internal mutexes initialization until libthr is loaded. This avoids recursion between calloc(3) and static pthread_mutex_t initialization.
- Reinstall signal handlers with wrapper on libthr load. The _rtld_is_dlopened(3) is used to avoid useless calls to sigaction(2) when libthr is statically referenced from the main binary.
In the process, fix openat(2), swapcontext(2) and setcontext(2) interposing. The libc symbols were exported at different versions than libthr interposers. Export both libc and libthr versions from libc now, with default set to the higher version from libthr.
Remove unused and disconnected swapcontext(3) userspace implementation from libc/gen.

Don't peek into MD structures from MI code. The getcontext(3) and setcontext(3) functions check the validify of the mcontext_t structs.

Bandaid to stop failing on non-i386 platforms. Add a big ugly #warning as a reminder.

Add signalcontext(), which lays down a signal frame onto a ucontext_t.

Include <stddef.h> to fix build problem when namespace pollution by <signal.h> (including <time.h> so that NULL is accidentally defined) is removed.
Style nits.

Add getcontext, setcontext, makecontext, and swapcontext. These functions are defined in SUSv2 and the latest POSIX spec.
