Add optional full_window argument to TuiWindow.write

Browse Source 
To prevent flickering when first calling erase, then write, this new
argument indicates that the passed string contains the full contents of
the window.  This fills every unused cell of the window with a space, so
it's not necessary to call erase beforehand.

Write @var{string} to the window. @var{string} can contain ANSI
terminal escape styling sequences; @value{GDBN} will translate these
as appropriate for the terminal.
If the @var{full_window} parameter is @code{True}, then @var{string}
contains the full contents of the window. This is similar to calling
@code{erase} before @code{write}, but avoids the flickering.
