Currently AWSY-with-DMD doesn't work on Windows. This is because `fix-stacks`
is initialized lazily, and by the time the initialization happens some file
descriptors for files are open, and that leads to some major Python2-on-Windows
sadness as described in the big comment in the commit.
To fix the problem, this commit adds an `init` function to `fix_stacks.py` so
that `fix-stacks` can be initialized eagerly, hopefully before any file
descriptors for files are open.
For `dmd.py`, other than fixing the AWSY problems, this has little effect,
because `fix-stacks` is always initialized.
For `utils.py`, which is used to process the output of most tests, this has a
more noticeable effect: the `fix-stacks` process is always spawned, rather than
being spawned only when needed. If no stack traces appear in the test output,
this means that `fix-stacks` is spawned unnecessarily. But it's cheap to spawn;
the expensive part only happens when stack traces start getting fixed. So I
think this change in behaviour is acceptable.
Furthermore, the commit adds a `finish` function to `fix_stacks.py`, so that
the `fix-stacks` process can be explicitly shut down. This has never been done
for processes spawned for any of the stack fixing scripts. It's never caused
problems on Linux/Mac, but it seems to be necessary on Windows to avoid
similar "this file is locked" problems with the test_dmd.js test.
The commit also renames some things to more standard Python style, e.g.
`json_mode` instead of `jsonMode`.
Finally, Android tests use `utils.py` from the repository but `fix_stacks.py`
from the Android host utils. Because the two scripts must be updated in tandem,
this commit also updates the Android host utils to a version that contains the
updated `fix_stacks.py`. Thanks to aerickson for packaging up the new Android
host utils and providing the change to the `hostutils.manifest` file.

Unfortunate, but it gets us back to where we were before `fix_stacks.py` came
along, and getting it working isn't worth the effort right now.

AWSY is built on marionette, so it inherits the option by default, we mostly
just need to propagate it properly. This also drops the --disable-webrender
option as it is now implied if --enable-webrender is not provided.

Ensure we force-disable webrender unless it is explicitly enabled
via the --enable-webrender flag. Also add missing env variables for
the telemetry_client.py case which appears to be a copy/paste error
that was not caught because we never run that test with WR enabled.

It's useful to get DMD reports even if we end up with negative
heap-unclassified. This catches any assertions during processing and makes
sure we move the reports to the upload dir even if there's a failure.
