The pth_uctx_save() and pth_uctx_restore() API functions
unfortunately were broken by design because they are C
functions. This leads to one more deadly nesting on the
run-time stack which effectively caused the pth_mctx_restore()
in pth_uctx_restore() to return to the end of pth_uctx_save()
but then the control flow unfortunately returns to the
pth_uctx_restore() caller instead of the pth_uctx_save() caller
because the call to pth_uctx_restore() had already overwritten the
run-time stack position where the original return address for the
pth_uctx_save() call was stored.
The only workaround would be to #define pth_uctx_save() and
pth_uctx_restore() as C macros, but this then would require that
lots of the GNU Pth internals from pth_mctx.c would have to be
exported in the GNU Pth API (which in turn is not acceptable). So,
the only consequence is to remove the two functions again from the
GNU Pth API.

Added a stand-alone sub-API for manual user-space context switching.
It is somewhat modeled after the POSIX ucontext(3) facility and
consists of an opaque data type pth_uctx_t and the management functions
pth_uctx_create(), pth_uctx_make(), pth_uctx_save(), pth_uctx_restore(),
pth_uctx_switch() and pth_uctx_destroy(). These functions are based on
the same underlying machine context switching facility (pth_mctx) the
threads in GNU Pth are using. This facility can be used to implement
co-routines without a full real multithreading environment or even to
implement an own multithreading environment. By rse.
