Continuing work to convert the hppa targets to multiarch partial.

Browse Source 
* hppa-tdep.c: (hppa_register_raw_size): New function replacing
       the body of macro REGISTER_RAW_SIZE.
       * hppa-hpux-tdep.c: Add new functions replacing macro bodies from
       config/pa/tm-hppah.h. These functions will be used to initialize
       the gdbarch structure.
       (hppa_hpux_pc_in_sigtramp): New function.
       (hppa_hpux_frame_saved_pc_in_sigtramp): New function.
       (hppa_hpux_frame_base_before_sigtramp): New function.
       (hppa_hpux_frame_find_saved_regs_in_sigtramp): New function.
       Add gdbcore.h #include.
       * config/pa/tm-hppa.h (REGISTER_RAW_SIZE): Change the definition
       of this gdbarch-eligible macro to a call to the new associated
       function.
       * config/pa/tm-hppah.h (PC_IN_SIGTRAMP): Likewise.
       (FRAME_SAVED_PC_IN_SIGTRAMP): Change the definition of this macro
       into a call to the new associated function.
       (FRAME_BASE_BEFORE_SIGTRAMP): Likewise.
       (FRAME_FIND_SAVED_REGS_IN_SIGTRAMP): Likewise.
       * Makefile.in (hppa-hpux-tdep.o): Add dependency on gdbcore.h.

/* Actually, for a PA running HPUX the kernel calls the signal handler
without an intermediate trampoline. Luckily the kernel always sets
the return pointer for the signal handler to point to _sigreturn. */

/* For HPUX:
The signal context structure pointer is always saved at the base
of the frame which "calls" the signal handler. We only want to find
the hardware save state structure, which lives 10 32bit words into
sigcontext structure.
Within the hardware save state structure, registers are found in the
same order as the register numbers in GDB.
At one time we peeked at %r31 rather than the PC queues to determine
what instruction took the fault. This was done on purpose, but I don't
remember why. Looking at the PC queues is really the right way, and
I don't remember why that didn't work when this code was originally
written. */
