Refactor sigcontextinfo.h

Browse Source 
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.
