[RFA]: TUI testsuite

[Stephane Carrez]

Hi!

I wrote a small TUI testsuite to check the gdb TUI mode.
The testsuite does not check for exact curses output because it would be
too terminal dependant. However, it checks enough output to be confident
that the TUI is functional.

tui-mode.exp checks that we can enter and leave TUI mode (^Xa) as well
as various window changes (^X2 binding). In this test, gdb is started
with -tui option.

tui-break.exp is inspired from gdb.base/break.exp and checks breakpoint
and single step in TUI mode.  gdb is started without -tui and TUI mode
is entered after program is loaded (it was easier for the test to do this way,
and well this also correspond to the way I use the TUI...).

tui-single-key.exp is similar but uses the SingleKey mode in which
several keys (c u d r s ...) are bound to gdb command. It also checks that
we can temporarily leave the SingleKey mode to give a long gdb command
(like break or info).

The TUI tests are not executed when gdb is not configured with --enable-tui.
To check this, gdb -help is run and the usage is parsed to see if -tui option
is reported.

Here are the results I've obtained.
