Fix colors in TUI mode in MS-Windows build with ncurses
The MS-Windows port of ncurses fails to switch to a color pair if
one or both of the colors are the implicit default colors. This
change records the default colors when TUI is initialized, and
then specifies them explicitly when a color pair uses the default
colors. This allows color styling in TUI mode on MS-Windows.
gdb/ChangeLog:
2019-03-14 Eli Zaretskii <eliz@gnu.org>
* tui/tui-io.c [__MINGW32__]: Include windows.h. Declare
ncurses_norm_attr.
(tui_initialize_io) [__MINGW32__]: Record the default terminal
colors in ncurses_norm_attr.
(apply_ansi_escape) [__MINGW32__]: If a color in a color pair is
"none", replace it with the default color recorded in
ncurses_norm_attr.
