This allows consumers of the font crate to handle errors instead of the
library panicking.

There was a lot of complexity around the threadsafe `Flag` type and
waking up the event loop. The idea was to prevent unnecessary calls to
the glutin window's wakeup_event_loop() method which can be expensive.
This complexity made it difficult to get synchronization between the pty
reader and the render thread correct. Now, the `dirty` flag on the
terminal is also used to prevent spurious wakeups. It is only changed
when the mutex is held, so race conditions associated with that flag
shouldn't happen.

This adds the ability to click and drag with the mouse and have the
effect of visually selecting text. The ability to copy the selection
into a clipboard buffer is not yet implemented.

All of the changes in this commit are due to clippy lints.

This adds a trait OnResize and a separate method handle_resize to the
display. Instead of having a callback to receive resize events, a list
of &mut OnResize are passed to this new method. Doing this allowed the
only RefCell usage in the codebase to be removed :).

This is part of an ongoing decoupling effort across the codebase and
tidying effort in main.rs. Everything to do with showing the window with
a grid of characters is now managed by the `Display` type. It owns the
window, the font rasterizer, and the renderer. The only info needed from
it are dimensions of characters and the window itself for sizing the
terminal properly. Additionally, the I/O loop has access to wake it up
when new data arrives.
