Change some void* to gdb_byte*

There are a bunch of places where a void* is implicitely casted into a
gdb_byte*.  The auto-insert-casts script added explicit casts at those
places.  However, in many cases, it makes more sense to just change the
void* to a gdb_byte*.

gdb/ChangeLog:

	* aarch64-tdep.c (stack_item_t): Change type of data to gdb_byte*.
	* arm-tdep.c (struct stack_item): Likewise.
	(push_stack_item): Add gdb_byte* cast.
	* avr-tdep.c (struct stack_item): Change type of data to gdb_byte*.
	(push_stack_item): Add gdb_byte* cast.
	* cli/cli-dump.c (dump_memory_to_file): Change type of buf to gdb_byte*
	and add cast.
	* cris-tdep.c (struct stack_item): Change type of data to gdb_byte*.
	(push_stack_item): Add gdb_byte* cast.
	* gcore.c (gcore_copy_callback): Change type of memhunk to gdb_byte* and
	add cast.
	* gdbtypes.h (print_scalar_formatted): Change type of first parameter to
	gdb_byte*.
	* h8300-tdep.c (h8300_extract_return_value): Change type of valbuf to
	gdb_byte* and remove unnecessary cast.
	(h8300h_extract_return_value): Likewise.

	gdb_byte* and remove unnecessary cast.
	(moxie_extract_return_value): Change type of dst to gdb_byte* and remove
	valbuf.
	* p-valprint.c (print_scalar_formatted): Change type of valaddr to
	gdb_byte*.
	* printcmd.c (void): Likewise.
	* python/py-inferior.c (infpy_read_memory): Change type of buffer to
