Refactor sigcontextinfo.h
This patch refactor sigcontextinfo.h header to use SA_SIGINFO as default
for both gmon and debug implementations. This allows simplify
profil-counter.h on Linux to use a single implementation and remove the
requirements for newer ports to redefine __sigaction/sigaction to use
SA_SIGINFO.
The GET_PC macro is also replaced with a function sigcontext_get_pc that
returns an uintptr_t instead of a void pointer. It allows easier convertion
to integer on ILP32 architecture, such as x32, without the need to suppress
compiler warnings.
The patch also requires some refactor of register-dump.h file for some
architectures (to reflect it is now called from a sa_sigaction instead of
sa_handler signal context).
- Alpha, i386, and s390 are straighfoward to take in consideration the
new argument type.
- ia64 takes in consideration the kernel pass a struct sigcontextt
as third argument for sa_sigaction.
- sparc take in consideration the kernel pass a pt_regs struct
as third argument for sa_sigaction.
- m68k dummy function is removed and the FP state is dumped on
register_dump itself.
- For SH the register-dump.h file is consolidate on a common implementation
and the floating-point state is checked based on ownedfp field.
The register_dump does not change its output format in any affected
architecture.
I checked on x86_64-linux-gnu, i686-linux-gnu, aarch64-linux-gnu,
arm-linux-gnueabihf, sparcv9-linux-gnu, sparc64-linux-gnu, powerpc-linux-gnu,
powerpc64-linux-gnu, and powerpc64le-linux-gnu.
I also checked the libSegFault.so through catchsegv on alpha-linux-gnu,
m68k-linux-gnu and sh4-linux-gnu to confirm the output has not changed.
