[RFC v2 6/9] replace convert_int_to_ascii with bin2hex

[Tom Tromey <tromey@redhat.com>]

convert_int_to_ascii is identical to bin2hex.  This removes the
former.  In this case I made the choice of which to keep on the basis
that I consider the name bin2hex to be superior to
convert_int_to_ascii.

2014-02-06  Tom Tromey  <tromey@redhat.com>

	* common/rsp-low.h (convert_int_to_ascii): Don't declare.
	* common/rsp-low.c (convert_int_to_ascii): Remove.

2014-02-06  Tom Tromey  <tromey@redhat.com>

	* ax.c (gdb_unparse_agent_expr): Use bin2hex, not
	convert_int_to_ascii.
	* regcache.c (registers_to_string, collect_register_as_string):
	Likewise.
	* remote-utils.c (look_up_one_symbol, relocate_instruction):
	Likewise.
	* server.c (process_serial_event): Likewise.
	* tracepoint.c (cmd_qtstatus, response_source, response_tsv)
	(cmd_qtbuffer, cstr_to_hexstr): Likewise.
