6d92b99dbc Add a terminal feature for enable/disable extended keys (supported by xterm and
mintty) and add an option to make tmux send it.

527f66ed23 Instead of having a default set of terminals in terminal-overrides that get XT
added and using that as a marker for xterm(1)-like, assume that if the
terminfo(5) entry already has XT or the clear capability starts with CSI then
the terminal is VT100-like and it should be safe to send DA requests. The DA
responses trigger additional features being added.

This is all to detect extensions if terminfo(5) is wrong or inadequate. If it
fails, tmux will just fall back to using the capabilities in the terminfo(5)
entry alone.

766b425d05 Overrides need to be applied both before and after features in case they

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terminfo(5) even in the presence of outdated ncurses(3) or terminfo(5)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.

a6129e9974 If we can identify the terminal as iTerm2 or as tmux, we can be sure
they support 256 and RGB colours, so set those flags too.

193e637de0 The terminal type was never as much use as I expected so remove it in
favour of a couple of flags for the features used (DECSLRM and DECFRA).
Also rename the flag for no xenl to be more obvious while here.

f4c7141f5d Do not lazily use BUFSIZ for "I don't care what size" when building
strings because it is only guaranteed to be 256 bytes and even the
default 1024 is not always enough. Reported by Gregory Pakosz.

fe7a871a23 Upstream ncurses has introduced terminfo capabilities to specify RGB
colour ("true" or "direct" colour). These consist of new entries (such
as "xterm-direct") which have a different setaf/setab implementation,
colors and pairs set to 0x1000000 and 0x10000, and a new RGB flag.

The setaf/setab definitions seem to be geared towards what ncurses (or
emacs maybe) needs, in that the new versions do only ANSI and RGB
colours (they can't be used for the 256 colour palette); they rely on
the silly ISO colon-separated version of SGR; and they use a weird
multiplication scheme so they still only need one argument. The higher
values of colors and pairs require a recent ncurses to parse.

tmux can use the RGB flag to detect RGB colour support (keeping the old
Tc extension for backwards compatibility for now). However, as we still
want to send 256 colour information unchanged when possible, the new
setaf/setab are awkward. So when RGB is present, reserve setaf/setab
only for ANSI colours and use the escape sequences directly for 256 and
RGB colours. (To my knowledge no recent terminal uses unusual escape
sequences for these in any case.)
