This fixes the execution of subprocesses on macOS which could sometimes
prevent actions like `SpawnNewProcess` or custom commands from launching
their processes correctly.
This fixes #2259.

This reverts the removal of the call to libc::daemon and instead adds an
annotation to ignore the deprecation warnings on macos.
This will not be an issue in the future since macOS is only discouraging
the use of `daemon`, but I'm not aware of any intention to actually
remove it.
This fixes #2211.

Since version 10.5 of macOS the libc::daemon call has been deprecated.
While it is recommended by macOS to use launchd instead, this is not
easily available on other unix platforms.
However since we just spawn a daemon process to prevent Alacritty from
spawning zombies, we can manually invoke `fork` in the child process to
cause a double-fork and re-parent the child process under init so it can
be reaped automatically.
Since the daemon call is not part of POSIX, using the double fork on all
unix platforms also has some portability advantages.

In cases where the Alacritty process had invalid std handles then
the ConPTY subprocess would fail to spawn. By setting appropriate
flags we prevent these handles from being passed to the ConPTY
subprocess.

This resolves a lot of NLL issues, however full NLL will be necessary to
handle a couple of remaining issues.
|
|
This makes use of the common double-fork behavior to prevent
spawning zombie processes every time a URL is clicked.

We moved to "cargo clippy" in 5ba34d4f9766a55a06ed5e3e44cc384af1b09f65 and
removing the clippy lint annotations in `src/lib.rs` does not cause any additional warnings.
This also changes `cargo clippy` to use the flags required for checking integration tests.

The previous format was extremely difficult for a human to parse.

This changes the cursor color config to use the `text` and `cursor`
properties instead of the current `foreground` and `background`
properties. The latter names stop making sense when dealing with cursors
like a vertical bar or underscore. In the new system, the block,
underscore, or vertical bar would always take the color of `cursor`, and
the text would take the color of `text` when using a block, or keep its
normal color when using the underscore or vertical bar.
A warning is now emitted on startup when the old form of cursor color
config is used. This will be a hard error in the future.

Previously, these could have crashed alacritty. Now, they simply print
an error message in Red to stderr. The Red format wrapper was moved to a
central location where both main.rs and the alacritty lib can access it.

Moving the window on macOS would cause a panic in certain circumstances.

Now uses serde_dervive \o/

This type and its implementations were seriously cluttering main.rs.

The previous scrolling + scroll region implementation exhibited display
corruption bugs in several applications including tmux, irssi, htop, and
vim. The new implementation doesn't seem to suffer from any of those
issues.
This implementation is able to `find /usr` on my machine (nearly 600k
lines) in ~2.0 seconds while st is able to do the same in ~2.2 seconds.
Alacritty is officially faster!

Of note are the `ansi` and `grid` modules becoming public. There are
several bits of unused code in each of these. In the case of `grid`, the
unused parts are generally useful, like some indexing implementations.
In ansi, there are pieces that will be used once the parser is more
complete. In any case, these modules are fairly generic and mostly
usable outside of Alacritty.
Unused cargo packages were also removed.

It's now possible to move around within Vim without the screen becoming
corrupt!
The ANSI parser now calls a (new) `set_scrolling_region` on the handler
when the DECSTBM CSI is received. In order to provide a sensible default
in case that the sequence doesn't include arguments, a TermInfo trait
was added which currently has methods for inspecting number of rows and
columns. This was added as an additional trait instead of being included
on Handler since they have semantically different purposes. The tests
had to be updated to account for the additional trait bounds.
The utilities module now has a `Rotate` trait which is implemented for
the built-in slice type. This means that slices and anything derefing to
a slice can be rotated. Since VecDeque doesn't support slicing (it's
a circular buffer), the grid rows are now held in a Vec to support
rotation.
For ergomomic access to the grid for scrolling and clearing regions,
additional Index/IndexMut implementations were added to the grid::Row
type.
Finally, a `reset` method was added to `Cell` which properly resets the
state to default (instead of just clearing the char). This supports
region clearing and also fixed a bug where cell backgrounds would remain
after being cleared.
