Correctly handle local sources for CSS3 fonts
Currently, servo panics for me when loading something like this:
```
@font-face {
font-family: "test family";
src: local(test font face);
}
```
That's due to a bug in `FontCacheTask`. `FontCacheTask` tries to get the value for the key
"test font face" from `self.web_families`, but previously initialized a value for the key "test family".
These two commits add an awkward test and fix the bug by not shadowing the variable `family_name`. Since the argument to `local()` should explicitly not be the name of a font family, the previous variable name was wrong and misleading anyways.

script_task.rs: Use self::MixedMessage in handle_msgs
handle_msgs contains many references to variants of MixedMessage.
The function should directly reference the variants instead of
prepending `MixedMessage::`.
Fixes#9169.

Remove the fontgroup address cache.
It's not clear to me that it actually helps. Moreover, it's wrong and
results in fonts randomly changing e.g. on GitHub when mousing over
elements.

Implement EventSource and update test expectations
Partial #8925.
Most of the processing model for `EventSource` are unimplemented because we currently don't have a fetch implementation.

webgl: Make a general way to get data from a JS array buffer view
This fixes an invalid length being reported from
`float32_array_to_slice` (which used the byte length), and also to
generalize getting data from a JS array buffer view, to reduce code
duplication.
The pending type safety issues, like where we could send a `UInt16Array`
where we expect a `Float32` one, should be solved by IDL bindings in
some cases, like `uniform[n]fv` or `vertexAttrib[n]fv`, and with extra
checks in others, like in the pending `texImage2D(..., ArrayBufferView)`.

Partial implementation of HTTP-network Fetch step
I've been working on making a partial implementation of HTTP-network Fetch[1] so that I can begin testing the entire Fetch protocol as implemented in Servo. The empty steps are intentionally so, including the incomplete Step 5, which I started without realizing I don't need to do basic testing.

Make "mach run" use --android by default when enabled in .servobuild
When `.servobuild` has `android = true`, the `mach run` command should default to running on Android.

The argument to `local()` is not a font family, but the name of a
»single font face within a larger family« according to
http://www.w3.org/TR/css3-fonts/#src-desc.
The previous implementation of `FontCache::run` would panic if the argument to
`local()` would not be the name of a font family present in `self.web_families`.
That happened since `FontCacheTask` tried to use the argument to `local()` as a
key for `self.web_families`, although it previously correctly initialized a
value for the `family` field of the `AddWebFont` command.
This test tries to add a web font to the `FontCacheTask`. The added web font
corresponds to the following CSS font definition:
```
@font-face {
font-family: "test family";
src: local(test font face);
}
```
This test fails, since `FontCacheTask` tries to get the value for the key
"test font face" from `self.web_families`, but previously initialized
a value for the key "test family".
This fixes an invalid length being reported from
float32_array_to_slice (which used the byte length), and also to
generalize getting data from a JS array buffer view, to reduce code
duplication.
The pending type safety issues, like where we could send a UInt16Array
where we expect a Float32 one, should be solved by IDL bindings in
some cases, like uniform[n]fv or vertexAttrib[n]fv, and with extra
checks in others, like in the pending texImage2D(..., ArrayBufferView).
