Introduce common/gdb_setjmp.h
This commit creates a new file, common/gdb_setjmp.h, to hold some
portability macros for setjmp/longjmp et al. that are used by the
exceptions subsystem and by the demangler crash catcher.
gdb/ChangeLog:
* common/gdb_setjmp.h: New file.
* Makefile.in (HFILES_NO_SRCDIR): Add common/gdb_setjmp.h.
* configure.ac: Move sigsetjmp check...
* common/common.m4: ...here.
* configure: Regenerate.
* cp-support.c (SIGJMP_BUF): Delete.
(SIGSETJMP): Likewise.
(SIGLONGJMP): Likewise.
* exceptions.h (gdb_setjmp.h): Include.
(setjmp.h): Do not include.
(EXCEPTIONS_SIGJMP_BUF): Delete.
(EXCEPTIONS_SIGSETJMP): Likewise.
(EXCEPTIONS_SIGLONGJMP): Likewise.
Replace all uses of EXCEPTIONS_SIG* macros with SIG* macros
from gdb_setjmp.h.
* exceptions.c: Likewise.
gdb/gdbserver/ChangeLog:
* config.in: Regenerate.
* configure: Likewise.
