Tom de Vries 628b136d64 [gdb/testsuite] Fix timeout in gdb.tui/resize-2.exp
When running test-case gdb.tui/resize-2.exp with taskset -c 0, I sometimes run
into:
...
tui disable^[[40;1H^M(gdb) PASS: $exp: tui disable
^M^[[K(gdb) FAIL: $exp: two prompt redisplays after resize (timeout)
...

The test-case does "Term::resize 24 80 0" while having the settings of an
earlier "Term::resize 40 90", so both dimensions change.

When TUI is enabled, we call Term::resize with wait_for_msg == 1, and the proc:
- calls stty to change one dimension,
- waits for the message (enabled by "maint set tui-resize-message on")
  confirming the resize has happened,
- calls stty to change the other dimension, and again
- waits for the message confirming the resize has happened.

Since TUI is disabled, we call Term::resize with wait_for_msg == 0 because the
message is not printed, so stty is called twice, and afterwards we check for
the results of the two resizes, which is the test that is failing.

The problem is that not waiting for a response after each stty call opens up
the possibility of the responses being merged.

Fix this by calling Term::resize twice, changing one dimension at a time, and
waiting for a single prompt redisplay after each one.

Tested on x86_64-linux.

		   README for GNU development tools

This directory contains various GNU compilers, assemblers, linkers, 
debuggers, etc., plus their support routines, definitions, and documentation.

If you are receiving this as part of a GDB release, see the file gdb/README.
If with a binutils release, see binutils/README;  if with a libg++ release,
see libg++/README, etc.  That'll give you info about this
package -- supported targets, how to use it, how to report bugs, etc.

It is now possible to automatically configure and build a variety of
tools with one command.  To build all of the tools contained herein,
run the ``configure'' script here, e.g.:

	./configure 
	make

To install them (by default in /usr/local/bin, /usr/local/lib, etc),
then do:
	make install

(If the configure script can't determine your type of computer, give it
the name as an argument, for instance ``./configure sun4''.  You can
use the script ``config.sub'' to test whether a name is recognized; if
it is, config.sub translates it to a triplet specifying CPU, vendor,
and OS.)

If you have more than one compiler on your system, it is often best to
explicitly set CC in the environment before running configure, and to
also set CC when running make.  For example (assuming sh/bash/ksh):

	CC=gcc ./configure
	make

A similar example using csh:

	setenv CC gcc
	./configure
	make

Much of the code and documentation enclosed is copyright by
the Free Software Foundation, Inc.  See the file COPYING or
COPYING.LIB in the various directories, for a description of the
GNU General Public License terms under which you can copy the files.

REPORTING BUGS: Again, see gdb/README, binutils/README, etc., for info
on where and how to report problems.
