[patch/comiting] Some ``char *'' -> ``const void *'' in regcache

[Andrew Cagney <ac131313 at ges dot redhat dot com>]

Hello,

This just cleans up some of the regcache interfaces so that they are 
easier to use.  No longer is a cast like:

	supply_register (...., (char *) &buf, ...);

needed.

committing,
Andrew

	* regcache.c (regcache_raw_write): Change buf parameter to a
	constant void pointer.
	(regcache_raw_read): Change buf parameter to a void pointer.
	(legacy_write_register_gen): Change myaddr parameter a constant
	void pointer.
	(supply_register): Change val parameter to a const void pointer.
	* regcache.h (regcache_raw_write): Update declaration.
	(regcache_raw_read): Update declaration.
	(supply_register): Update declaration.
