This commit adds the concept of a "title stack" to the terminal. Some programs
(e.g. vim) send control sequences `CSI 22 ; 0` (push title) and `CSI 23 ; 0`
(pop title).
The title stack is just a history of previous titles. Applications can push
the current title onto the stack, and pop it back off (setting the window title
in the process).
Fixes#2840.
This takes the latest glutin master to port Alacritty to the EventLoop
2.0 rework.
This changes a big part of the event loop handling by pushing the event
loop in a separate thread from the renderer and running both in
parallel.

A semicolon in a title OSC should be interpreted literally, not as a parameter
separator, but the OSC parser is very simple and does not know about arities of
commands.
Therefore, this patch takes all the parameters returned by the OSC parser and
reconstructs the original string by interspersing semicolons. Now an OSC like
'\e]2;hello;world' will set the title to 'hello;world' and not 'hello' like
before.
The legacy xparsecolor implementation assumed that the \007 ending would
be passed to the parser, however it never is. This caused colors in the
format #rrggbb to be interpreted as #rrggb, leading to incorrect colors
showing up in Alacritty.
Fixes#2759.
Escape sequences in xterm are parsed according to xparsecolor.
xparsecolor supports 1, 2, 3, and 4 digit hex colors.
Previously, only 2 digits were supported.
This also fixes a bug where "fX" was parsed as "0xf", where X is an invalid character.
The response to a request for fg/bg must be a valid escape sequence.
The current response uses 4-digit hex, which was previously invalid.
Instead of ignoring unexpected intermediates in CSI escape sequences,
the intermediates are now explicitly checked and the escape sequence is
rejected when an unexpected intermediate is found.
Fixes#2171.
The cursor rework introduced a regression where cursor color was always picked
from a config file, rather then using `ansi::NamedColor::Cursor` for this
purpose.
This commit also removes `CursorText` option from `NamedColor` enum,
since we can't speculate with `CursorText` during runtime.
