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.

Add 'use statements with extraneous spaces' tidy check
I added simple check routine for 'use statements with extraneous
spaces' and codes that breaks the check routine in rust_tidy.rs.
* Added a code that using 'use statements with extraneous spaces' code
in rust_tidy.rs
* Added assertion code in test_tidy.py.
* check_rust function in tidy.py now recognizes the simple case in
the 'use statements with extraneous spaces'.
* Ran tidy check on rust code and modified a
code(tests/unit/style/parsing/inherited_text.rs) that is not passing
on this new tidy check.
TODO: this code has to be refactored to support more general cases.

Sometimes clippy gets outdated by months, and its current support setup
means that each Servo component need to opt into it by depending on
the plugins crate manually, and not all components do that.
