[RFA] trace_find_tracepoint_command bug fix

[David Taylor <taylor at cygnus dot com>]

In trace_find_tracepoint_command (tracepoint.c), we find the line:

	tdp = parse_and_eval_address (args);

Since the tdp is just an integer, I'd like to change that to instead
read:

	tdp = parse_and_eval_long (args);

The ChangeLog entry would be:

	* tracepoint.c (trace_find_tracepoint_command): Replace call to
	parse_and_eval_address with a call to parse_and_eval_long as
	we are evaluating an integer, not an address.
