to_resume(). (target_resume): Add pid argument.

comment.
* gdbtypes.h, gdbtypes.c: Use const in decl of
cplus_struct_default, now that pa-gas assembler has been fixed.
* hppah-nat.c: Formatting.
* hppah-tdep.c: Remove lots of useless externs for variables we
don't use.
* (find_unwind_entry): Speed up by using binary search, and a one
entry cache.
* (rp_saved): New routine to see what unwind info says about RP
being saved on the stack frame.
* (frame_saved_pc): Look for prologue to see if we need to
examine the stack for the saved RP or not.
* (init_extra_frame_info): Check for prologue, instead of
framesize to determine if we are frameless or not.
* (frame_chain_valid): Stop backtraces when we run into _start.
* (push_dummy_frame): Reformat to make more readable.
* (find_dummy_frame_regs): ditto.

* tm-hppa.h: Move contents of SKIP_PROLOGUE into hppah-tdep.c.

mechanism and related macros.
branch targets to compute target address using const from previous
instruction if necessary.
* Add `Q' operator to print out bit position field various
instructions.

cleanups, use new code from Utah.
* (store_inferior_registers): Update to new code from Utah.

* Remove decl of errno, #include wait.h and target.h.
* (frame_saved_pc): Check `flags' pseudo-register to see if we
were inside of a kernel call. If so, then PC is in a different
register. Also, mask out bottom two bits of all PCs so as not to
confuse higher level code.
* (push_dummy_frame): Create from #define in tm-hppa.h.
* (find_dummy_frame_regs): Update from Utah.

so as to avoid confusing the user.
* (just before step_over_function:): Use stop_func_start, not
stop_pc when checking for the existance of line number info.
stop_func_start will reflect the proper address of the target
routine, not of the stub that we may be traversing to get there.
* tm-hppa.h: define SKIP_TRAMPOLINE_CODE and IN_SOLIB_TRAMPOLINE
to deal with the stubs that PA compilers sometimes stick between
callers and callees. Also, define FLAGS_REGNUM for access to the
`flags' pseudo-reg.
* (REGISTER_CONVERT_TO_VIRTUAL, REGISTER_CONVERT_TO_RAW): Use
memcpy, not bcopy.
