RFA: Add functions for storing integers

[Jim Blandy <jimb at zwingli dot cygnus dot com>]

I could have sworn we had functions that did this already.

2001-11-09  Jim Blandy  <jimb@redhat.com>

	* corefile.c (write_memory_unsigned_integer,
	write_memory_signed_integer): New functions.
        (write_memory): Move to be with other write_memory_* functions.
	* gdbcore.h (write_memory_unsigned_integer,
	write_memory_signed_integer): New declarations.
