Move bindings tests out of the style crate
This cuts in almost half the time to run:
```
touch components/style/lib.rs
./mach test-stylo
```

Support for Android armv7 and aarch64 target triples
<!-- Please describe your changes on the following line: -->
Support for Android armv7 and aarch64 target triples in python build scripts (build + packaging)
`--android` build parameter works as always (arm-linux-androideabi still the default)
`./mach build --release --android`
New compilation modes for android
`./mach build --release --target=arm-linux-androideabi`
`./mach build --release --target=armv7-linux-androideabi`
`./mach build --release --target=aarch64-linux-android`
See https://github.com/servo/servo/issues/11921. When all crates are ready we'll switch default android compilations to` armv7-linux-androideabi` target triple.

This will help avoid situation where we upgrade Servo and dependencies
for a Rust breaking change that hasn’t reach Nightly yet.
The old behavior is still available with `./mach rustup --master`.
Generate atom files at build-time
The commits here basically do the following things:
1. move all generated files for gecko into "gecko/generated" so that we can copy all of them around
2. make regen_atoms.py generate file to the out dir rather than in-tree
3. make the build script invoke regen_atoms.py when bindgen feature is enabled

Avoid searching for old nightlies in missing dirs
These directories may be missing (e.g. a first time build or due to Buildbot cleaning),
so don't try to look inside them for old nightlies if so.
I noticed this in http://build.servo.org/builders/arm32/builds/6815/steps/shell__1/logs/stdio.

switch gecko_bindings over to the gecko_debug feature [DO NOT MERGE]
...so that they use the correct Gecko structs regardless of whether Rust
code is being compiled with debug assertions or not.
This is the second part of the Servo-side changes for https://bugzilla.mozilla.org/show_bug.cgi?id=1357556
- [X] `./mach build -d` does not report any errors
- [X] `./mach test-tidy` does not report any errors
- [X] These changes do not require tests because building is a sufficient test.

Add a new `-keep` flag to `./mach clean-nightlies` to control how many
nightlies to keep, which keeps the n most recent nightlies found in git.
Use this to clean old nightlies at the start of each build,
currently keeping 3 nightlies at a time.
`mach bootstrap` will finish succesfully,
but then segfault inside glibc while exiting.
It seems to have to do with the MarkupSafe library used by Mako;
delaying the Mako import from the top level to inside functions where it
is used avoids the problem.
(It seems to interact with the call to pip to install the Salt
requirements in the virtualenv, as commenting that pip call out
separately will also fix the segfault.)
Also, use the Mako installed in the Python virtualenv while running
packaging commands (instead of the one from the bundled zip file),
and cleanup imports in the package_commands.py file.
Add env var for local saltfs root during bootstrap
<!-- Please describe your changes on the following line: -->
This enables using the environment variable `SERVO_SALTFS_ROOT` to use a local copy of the saltfs tree for `./mach bootstrap`. The immediate use case is to add a test for `./mach bootstrap` to saltfs itself, to ensure Salt changes or refactors don't break `./mach bootstrap`.
I tested this locally in an Ubuntu Trusty VM.

`incremental = true` can be set in the `[build]` section of `.servobuild`
to enable incremental compilation.
In `./mach build-geckolib`, which uses a stable version of the compiler,
this would cause a warning repeated for each invocation of rustc:
```
warning: the option `Z` is unstable and should only be used on the nightly
compiler, but it is currently accepted for backwards compatibility;
this will soon change, see issue #31847 for more details
```
This PR disables incremental compilation for `build-geckolib`,
regardless of `.servobuild` settings.
