This patch introduces setjmp() and ongjmp() primitives to enable
standard setjmp/longjmp style execution. Both APIs parameters take a
pointer to struct jmpbuf type, which hosts CPU registers saved/restored
during jump.
As per the standard usage:
- setjmp() return 0 when a jump is setup; and a non-zero value when
returning from jump.
- The caller of setjmp() must not return, or otherwise update stack
pointer since.
