* config/cpu32bug.exp, config/est.exp, config/hppro.exp,

	* config/cpu32bug.exp, config/est.exp, config/hppro.exp,
	config/rom68k.exp:  New tcl glue for the appropriate monitors.
	These all just end up calling monitor.exp.
	* config/monitor.exp (gdb_target_monitor):  Handle `Connection
	refused' by retrying.  Cleanup some timeout issues.
	* (gdb_load):  Reduce timeout.  Cleanup some timeout issues.
	* lib/gdb.exp (gdb_test gdb_test_exact):  Upvar timeout so that
	callers don't have to set/restore global timeout variable.

	* The following set of changes centralizes management of the global
	timeout	variable.  This way, it can be set in one target dependent
	place instead of dozens of places scattered throughout the test suite.
	If you need to lengthen a timeout, then you should either set timeout
	in one of the config/{target}.exp files, or multiply it by a factor.
	Setting it to an absolute value is always going to lose for some
	targets.
