Fix support for Linux/i386 signal trampolines. The old approach
didn't work for Linux 2.2 and beyond, and didn't work with recent
versions of the GNU C library.
* i386-tdep.c (LINUX_RT_SIGTRAMP_INSN0, LINUX_RT_SIGTRAMP_OFFSET0,
LINUX_RT_SIGTRAMP_INSN1, LINUX_RT_SIGTRAMP_OFFSET1): New defines.
(linux_rt_sigtramp_code): New variable.
(LINUX_RT_SIGTRAMP_LEN): New define.
(i386_linux_rt_sigtramp_start): New function. Detect start of
signal trampolines for RT signals.
(i386_linux_sigtramp): Removed.
(i386_linux_in_sigtramp): New function.
(i386_linux_sigcontext_addr): New function. Recognize the names
of the signal tranmpolines used by recent versions of the GNU C
library, and add support for RT signals.
(LINUX_SIGCONTEXT_PC_OFFSET, LINUX_SIGCONTEXT_SP_OFFSET): New
defines. Moved here from config/i386/tm-linux.h.
(i386_linux_sigtramp_saved_pc, i386_linux_sigtramp_saved_sp):
Reimplement in terms of i386_linux_sigcontext_addr.
* config/i386/tm-linux.h (LINUX_SIGCONTEXT_SIZE): Removed.
(LINUX_SIGCONTEXT_PC_OFFSET, LINUX_SIGCONTEXT_SP_OFFSET):
Moved to i386-tdep.c.
(IN_SIGTRAMP): Redefine to call i386_linux_in_sigtramp.
