[PATCH 3/4] gdb: Extend the trad-frame API
Adds two new functions to the trad-frame API and update the internals
of trad-frame to use the new functions. These functions will be used
in later commits.

* trad-frame.h (trad_frame_set_realreg): Declare.
(trad_frame_set_addr): Declare.
* trad-frame.c (trad_frame_set_realreg): Define new function.
(trad_frame_set_addr): Define new function.
(trad_frame_set_reg_realreg): Use new function.
(trad_frame_set_reg_addr): Use new function.
