Previously chvideomode(1) used {get,set}termmode(2) as well as
tcgetwincurpos(2), which are non-standard and only work in the kernel
terminal.
This necessitates changing the keybind for exiting the menu from esc to
Q, as there is no good standard way to disambiguate between escape
character by itself and the start of an escape sequence.
Pagination code deals with two indices for video modes, one relative to
the start of video modes array and one relative to the start of current
page. Previously when displaying the list of modes, the video mode array
would be accessed using the one relative to the start of the current
page, meaning that pages 2 and onwards displayed repeats of the video
modes on page 1. This changes the the display code to use indices
relative to the start of the video modes array when accessing the array.
Previously setting a mode from the command line would only work if it
was one of the pre-set resolutions offered by the driver. If the driver
supported custom resolutions and a user tried to set one on the command
line, chvideomode(1) would instead launch in interactive mode.
Previously chvideomode(1) used "WIDTHxHEIGHTxBPP" on the command line
while interactively it used "BPP x WIDTH x HEIGHT". Change everything
to "WIDTHxHEIGHTxBPP".
