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.
