Add the HAVE_INIJMP symbol to be set by architectures that support initjmp(), a non-standard extension to setjmp()/longjmp() allowing to initialize a jump buffer with a function pointer and a stack pointer. This will be useful to later introduce threads. With this new function it becomes possible to longjmp() to a particular function pointer (rather than to a point previously reached during program execution as is the case with setjmp()), and with a custom stack. Both things are needed to spin off a new thread. Then the usual setjmp()/longjmp() pair is enough to save and restore a context, i.e., switch thread. Add the initjmp() prototype to <include/setjmp.h> since it is common to all architectures. Add an entry to the API documentation: doc/api/setjmp.rst.
