[RFC 11/23] Drop regset_alloc()

[Andreas Arnez <arnez@linux.vnet.ibm.com>]

Now that all invocations of regset_alloc() have been removed, the
function is dropped.  Since regset_alloc() was the only function
provided by regset.c, this source file is removed as well.

gdb/
	* Makefile.in (SFILES): Delete "regset.c".
	(COMMON_OBS): Delete "regset.o".
	* regset.c: Remove.
	* regset.h (regset_alloc): Delete prototype.
