This commit makes use of the allsorts font parser to
parse out matching fonts found under the `font_dirs`
locations.
The matching is imperfect but sufficient for my ad-hoc
local tests.
Using allsorts for this parsing/matching means that we
can implement font_dirs on all platforms; previously it
was only available when using some plumbing from font-kit.

This commit adds two new font system variants that are currently
implemented only on Windows:
* FontKit - uses fontkit both for font discovery and rasterizing
* FontKitAndFreeType - uses fontkit for font discovery but freetype
for rasterizing
To a certain extent, FontKitAndFreeType obsoletes FontLoaderAndFreeType
and I'll be looking at removing it once I can test the build on macOS.
The FontKit impl has bad metrics and also crashes during shaping
on Windows, so it's not ready to be used by default.
Streamline the travis deploy builds; when TRAVIS_TAG is set
we'll run `--release` builds.
Don't error out in fontconfig/build.rs if fontconfig is not
installed. This makes it possible to `cargo test --all` again
on the mac at the cost of potentially making it harder to troubleshoot
problems with not having fontconfig installed on linux.
However: the get-deps script is responsible for installing that.
This is primarily for macos where the default freetype
installation is unable to render color emoji, but should also
help make things more consistent across the various platforms.
It's a little bit awkward on linux because the font-loader crate
pulls in the now-conflicting servo-font* crates. I've disabled
font-loader on linux systems; it's just calling fontconfig under
the covers anyway.
This is an unfortunately large diff that:
* Separates Tab ownership from TerminalWindow
* Introduces a Mux container for all of the tabs in the application,
across all windows
* Moves ownership of processing pty responses to the mux; it sets
up and has logic to process data for the ptys and apply to the
tabs
I've moved the logic for processing new tab and new window hotkeys
to the TerminalWindow's themselves as we need some context to
associate the tab with the right window and to create a new window.
I think that will simplify and allow unifying more code.
I've added dingbats to the fallback list on macos as that is needed
for some symbols we use in tools at work.
With that, and some tweaks for allowing for missing letter glyphs
when loading a symbol font as a fallback, we can make that the
default for macOS

This results in a less blurry display.
As a bonus, this lays down some plumbing for changing the font
size on the fly.
