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.
