Remove global traceframe_fun and traceframe_sal

I happen to see traceframe_fun and traceframe_sal are static variables,
which are not necessary to me.  They are only used in set_traceframe_context,
and they are not stateful.  This patch is to remove them.

gdb:

	* tracepoint.c (traceframe_fun): Remove.
	(traceframe_sal): Remove.
	(set_traceframe_context): Add local variables.
