When the same warning is thrown on the each rendering iteration, it'll
force alacritty to always render.

The `SizeInfo` is a SizeInfo used for rendering, which contains
information about padding, and such, however all the terminal need is
number of visible lines and columns.

Previously Alacritty would always initialize only a single terminal
emulator window feeding into the winit event loop, however some
platforms like macOS expect all windows to be spawned by the same
process and this "daemon-mode" can also come with the advantage of
increased memory efficiency.
The event loop has been restructured to handle all window-specific
events only by the event processing context with the associated window
id. This makes it possible to add new terminal windows at any time using
the WindowContext::new function call.
Some preliminary tests have shown that for empty terminals, this reduces
the cost of additional terminal emulators from ~100M to ~6M. However at
this point the robustness of the daemon against issues with individual
terminals has not been refined, making the reliability of this system
questionable.
New windows can be created either by using the new `CreateNewWindow`
action, or with the `alacritty msg create-window` subcommand. The
subcommand sends a message to an IPC socket which Alacritty listens on,
its location can be found in the `ALACRITTY_SOCKET` environment
variable.
Fixes #607.

Previously Alacritty was using two different ways to reference lines in
the terminal. Either a `usize`, or a `Line(usize)`. These indexing
systems both served different purposes, but made it difficult to reason
about logic involving these systems because of its inconsistency.
To resolve this issue, a single new `Line(i32)` type has been
introduced. All existing references to lines and points now rely on
this definition of a line.
The indexing starts at the top of the terminal region with the line 0,
which matches the line 1 used by escape sequences. Each line in the
history becomes increasingly negative and the bottommost line is equal
to the number of visible lines minus one.
Having a system which goes into the negatives allows following the
escape sequence's indexing system closely, while at the same time making
it trivial to implement `Ord` for points.
The Alacritty UI crate is the only place which has a different indexing
system, since rendering and input puts the zero line at the top of the
viewport, rather than the top of the terminal region.
All instances which refer to a number of lines/columns instead of just a
single Line/Column have also been changed to use a `usize` instead. This
way a Line/Column will always refer to a specific place in the grid and
no confusion is created by having a count of lines as a possible index
into the grid storage.

When formatting text for display in the message bar, Alacritty was using
the byte length of the text instead of the glyph count. This lead to
unnecessary blank space at the end of lines due to overestimation of
their length.
There also were no extra spaces inserted after fullwidth characters,
leading to Alacritty giving them only a single cell of space. In line
with the rest of Alacritty's rendering, a wide char spacer whitespace is
now inserted in the message bar after glyphs which should occupy two
cells.
Fixes #4250.

This changes the minimum terminal dimensions from 2 lines and 2 columns,
to 1 line and 2 columns.
This also reworks the `SizeInfo` to store the number of columns and
lines and consistently has only the terminal lines/columns stored,
instead of including the message bar and search in some places of the
Alacritty renderer/input.
These new changes also make it easy to properly start the selection
scrolling as soon as the mouse is over the message bar, instead of
waiting until it is beyond it.
Fixes #4207.

This commit completes the effort to use config colors for
message bar content by picking red/yellow from user's
colors.normal.{red,yellow} for error/warning messages
instead of fixed colors.
It also removes alacritty_terminal::term::color::RED and
alacritty_terminal::term::color::YELLOW from the alacritty_terminal API,
bumping its version to 0.11.0-dev.
Fixes #4116.

This commit removes font dependency from alacritty_terminal,
so it'll simplify the usage of alacritty_terminal as a library,
since you won't link to system's libraries anymore. It also
moves many alacritty related config options from it.
Fixes #3393.
