retire restore_cursor and the force-redraw optimization (for now) don't consider restore_cursor as a public interface and while there rename it as restore_curs_x, as it describes better the behaviour of the function. I have to disable the buffer->force-redraw optimization, at least from now, given that cmd.c don't update curs_y anymore, and with that optimisation in place the cursor y position doesn't get updated upon redraw. Add a comment as a future note though.

introduce erase_buffer

optimisation: cache the top_line vline instead of using the line_off + vline_nth, cache the current top line.

allow styling the minibuffer and modeline too

allow `bind map key cmd' in config file

move the list of cmd to its own file

kill lineface_descr and move its fields into line_face

rename config_apply_color -> config_apply_style

add support for custom protocol proxies

add save_excursion and restore_excursion

allow changing the colors/attributes of the tabline

allow changing the attributes `attr' now follows the same rule as `fg' and `bg', with the three airity variant. Attributes by themselves are a comma-separated list of keywords, each one representing a ncurses attribute.

use term default color by default for every line type

allow customizing left and right padding + use_default_colors

allow changing the background color of the body window
