efb5e58c38 Restore previous behaviour so that C-X remains the same as C-x. Instead,
translate incoming extended keys so that they are consistent.

ba99996676 Fixes for extended keys: 1) allow C-x and C-X to be bound separately
since some terminals report them differently 2) use the "backspace"
option to translate backspace 3) map ctrl which are have the ctrl
implied (such as C-x) properly when the terminal reports both the key
and the modifier.

Note that any key bindings for C-X where C-x is meant must now be
changed.

f2dfc2759e Escape+Up and the other arrow keys should be kept as Escape+Up and not
converted to M-Up. Do not give them the implied meta flag so they don't
match the M-Up entry in the output key tree. Fixes problem with vi
reported by jsing@.

0ab82d9531 Add a terminal feature for enable/disable extended keys (supported by
xterm and mintty) and add an option to make tmux send it. Only forward
extended keys if the application has requested them, even though we use
the CSI u sequence and xterm uses CSI 27 ~ - this is what mintty does as
well.

c91b4b2e14 Tidy up the terminal detection and feature code and add named sets of
terminal features, each of which are defined in one place and map to a
builtin set of terminfo(5) capabilities. Features can be specified based
on TERM with a new terminal-features option or with the -T flag when
running tmux. tmux will also detect a few common terminals from the DA
and DSR responses.

This is intended to make it easier to configure tmux's use of
terminfo(5) even in the presence of outdated ncurses(3) or terminfo(5)
databases or for features which do not yet have a terminfo(5) entry.
Instead of having to grok terminfo(5) capability names and what they
should be set to in the terminal-overrides option, the user can
hopefully just give tmux a feature name and let it do the right thing.

The terminal-overrides option remains both for backwards compatibility
and to allow tweaks of individual capabilities.

tmux already did much of this already, this makes it tidier and simpler
to configure.

835a6c0cf0 Be more specific in the DSR we are looking for so it doesn't get

never asked for it.

d52f579fd5 Up to now, tmux sees \033\033[OA as M-Up and since we turned on
xterm-keys by default, generates \033[1;3A instead of
\033\033[OA. Unfortunately this confuses vi, which doesn't understand
xterm keys and now sees Escape+Up pressed within escape-time as Escape
followed by A.

The issue doesn't happen in xterm itself because it gets the keys from X
and can distinguish between a genuine M-Up and Escape+Up.

Because xterm can, tmux can too: xterm will give us \033[1;3A (that is,
kUP3) for a real M-Up and \033\033OA for Escape+Up - in fact, we can be
sure any \033 preceding an xterm key is a real Escape key press because
Meta would be part of the xterm key instead of a separate \033.

So change tmux to recognise both sequences as M-Up for its own purposes,
but generate the xterm version of M-Up only if it originally received
the xterm version from the terminal.

This means we will return to sending \033\033OA instead of the xterm key
for terminals that do not support xterm keys themselves, but there is no
practical way around this because they do not allow us to distinguish
between Escape+Up and M-Up. xterm style escape sequences are now the de
facto standard for these keys in any case.

Problem reported by jsing@ and subsequently by Cecile Tonglet in GitHub
issue 907.

0ace779cde Initial attempt to make use of left and right margins if the terminal
supports them (that is, if it advertises itself as a VT420 - probably
just xterm). These are the vertical equivalent of the scroll region and
allow much faster scrolling of panes that do not take up the full width
of the terminal.
