Move jmp-related stuff from signal.h to unwind.h.

* gc.c: Include "unwind.h" for jmp_buf.

* signal.h (struct jmp): All versions removed from here.
(jmp_save, jmp_restore): Declarations removed from here.
(EJ_DBG_MEMB): Macro removed.
(extended_jmp_buf): Struct type removed.
(extended_setjmp, extended_longjmp): Macros removed.
(extjmp_save, extjmp_restore): Declarations removed.

* unwind.h (struct jmp): Declared here.
(jmp_save, jmp_restore): Declared here.
(EJ_DBG_MEMB): Macro moved here.
(extended_jmp_buf): Struct type moved here.
(extended_setjmp, extended_longjmp): Declared here.
(extjmp_save, extjmp_restore): Declared here.
