[patch/gdbserver] Be slightly more verbose

[Daniel Jacobowitz <drow@false.org>]

These patches normalize gdbserver's output in a couple of cases.  Now, for
both normal and attach operation, and for both serial and TCP operation,
gdbserver will print out one line of output before it is ready for input
and another line of output after it is ready for input, without blocking.
This lets me update the test harness to not issue "target remote" until
gdbserver is actually ready for a connection; on very slow targets, like the
one I've been using all week, this can prevent time-consuming retries.
No change in testsuite results, just a nice change in testsuite run time.

Will commit in a bit.

	* remote-utils.c (remote_open): Print a status notice after
	opening a TCP port.

	attaching.
