There's no reason to call refresh in tui_resize_all. This call

* tui/tui-win.c (tui_resize_all): Don't call refresh.
The TUI has long had code to resize the locator, using 2 as the
height. However the code has "1" in a comment, like:
locator->resize (2 /* 1 */ ,
This patch fixes the resizing code to set the height to 1. Doing this
revealed what was probably the reason for setting the height to 2 in
the first place: this caused the locator window to scroll. However,
this is easily handled by calling scrollok on the locator window.

Readline 8.0 has a feature that lets an application name a keymap.
This in turn makes it simpler for users to bind keys in keymaps in
their .inputrc.
This patch gives a name to the TUI SingleKey keymap, so that
additional bindings can be made there. For example:
$if gdb
set keymap SingleKey
"X": "echo hello\\n\n"
$endif
The call to rl_initialize, in tui_initialize_readline, had to be
removed so that .inputrc was not read too early. Note that Readline
explicitly documents that this call is not needed.

The TUI has two duplicate "re-render this window" methods, "rerender"
and "refresh_all". They differ only slightly in semantics, so I
wanted to see if they could be unified.
After looking into this, I decided that refresh_all was not needed.
There are 4 calls to tui_refresh_all_win (the only caller of this
method):
1. tui_enable. This sets the layout, which renders the windows.
2. tui_cont_sig. Here, I think it's sufficient to simply redraw the
current window contents from the curses backing store, because gdb
state didn't change while it was suspended
3. tui_dispatch_ctrl_char. This is the C-l handler, and here it's
explicitly enough to just refresh the screen (as above).
4. tui_refresh_all_command. This is the command equivalent of C-l.
So, this patch removes this method entirely and simplifies
tui_refresh_all_win.

The call to touchwin in tui_gen_win_info::refresh_window was an

This patch starts with the observation that the code in
tui_data_window::display_registers_from can all be replaced with a
call to resize. To make this work propertly, it also changes
tui_display_register to be the "rerender" method on
tui_data_item_window.
The refresh_window method is needed due to the use of nested windows
here. The ncurses man page makes it sound like this is not very well
supported; and experience bears this out: negelecting the touchwin
call in this path will cause the register window to blank when
switching focus.

I combined several small changes into one patch here. I believe I
started by noticing that the "title" is not needed by tui_gen_win_info
and could be self-managing (i.e. std::string). Moving this revealed
that "can_box" is also a property of tui_win_info and not
tui_gen_win_info; and this in turn caused the changes to
tui_make_window and box_win.

The TUI execution info window is unusual in that it is always linked
to a source or disassembly window. Even updates of its content are
handled by the source window, so it really has no life of its own.
This patch removes this window entirely and puts its functionality
directly into the source window. This simplifies the code somewhat.
This is a user-visible change, because now the box around the source
(or disassembly) window encloses the execution info as well. I
consider this an improvement as well, though.
Note that this patch caused ncurses to start emitting the "CSI Z"
sequence, so I've added this to the test suite terminal
implementation.
