Prefer length and percentage for word spacing
<!-- Please describe your changes on the following line: -->
The goal is to make use of `LengthOrPercentage` for word spacing in `ShapingOptions`, but since it makes use of `f32` which doesn't implement `Hash`, we're going for `NotNan<f32>` from [ordered-float](https://github.com/reem/rust-ordered-float/), which supports hashing. Instead of implementing `Hash` for `LengthOrPercentage` and thereby the inner types like `CSSFloat`, `CalcLengthOrPercentage`, etc., we convert it to `(Au, NotNan<f32>)`.

Add more shell script lints
<!-- Please describe your changes on the following line: -->
The "$(some_command arg1 arg2)" form is preferred to the
`some_command arg1 arg2` form because it nests unambiguously.
Add a lint for this to tidy.

Add linting for shell scripts

This changes tidy to check shell scripts for the proper shebang and
options. It does not check that variables are formatted correctly. It
also adds a check for the MPL 2.0 license in shell scripts.

Attach more signals to the backtrace signal handler.
These changes should enable meaningful backtraces in more unusual situations where the program would otherwise exit almost silently.

This currently breaks Servo on Android, because there are a number of
interdependent changes that cannot easily land serially in a way that
keeps it working throughout. We expect to fix this in the near future.

Removed panic channel, replaced by integrated logging and issue reporting
<!-- Please describe your changes on the following line: -->
Remove the previous ad hoc panic channel, replace it by an integrated logging and panicking mechanism, including crash reporting. All thread panics are now reported, not just content threads.

Send log messages to the constellation
<!-- Please describe your changes on the following line: -->
Send all warnings and errors to the constellation. Warnings are bufferred up, and included in any subsequent error reports. Errors are reported in the same way as panics.
Note that this can't merge yet, as it needs https://github.com/rust-lang-nursery/log/pull/86 to land.
