Remove the _UCONTEXT_TO_SIGCONTEXT() and _SIGCONTEXT_TO_UCONTEXT() macros 

as nothing uses them and they wouldn't work as _MCONTEXT_TO_SIGCONTEXT()
and _SIGCONTEXT_TO_MCONTEXT() got deleted a while ago.

* The following macros are used to convert from a ucontext to sigcontext,

* The only valid use of these macros is to convert a ucontext to a

* ucontext after the handler has returned.

* The _MCONTEXT_TO_SIGCONTEXT() and _SIGCONTEXT_TO_MCONTEXT() macros
* should be provided by <machine/signal.h>.
