Because the web platform test harness doesn't recognize them and annotates them
with `CRITICAL`, which is disconcerting, even though those errors are typically
not harmful.

Note how the executable bit, which is the only one we look at, and which
is where we get exeExeAddr from (0x5587df96b000 in this case) is in the
middle of the executable, but the library will span all four ranges.
Check for whether the library _contains_ the start address of the
executable region instead of whether it starts with it.

Renamed some variables to be more generic. Their type is going to change in the next patch, and that type doesn't need to be in the names; also it will make the next patch easier to review.

Instead of a potentially-null pointer to a `ProfileBufferEntryWriter`, we are now providing a `Maybe<ProfileBufferEntryWriter>`, which is safer.

This ensures we don't run every build with every push via ./mach try auto. It
introduces a new 'optimization-overrides' try_config that can be used to
replace optimizations. For now, there is no user interface to pass this in via
the 'mach try' command line.

Changes:
Applies the `filter_tasks_by_blacklist` method to try syntax pushes as well.
- moved `TARGET_TASK_BLACKLIST`and `filter_tasks_by_blacklist` method to live in `taskcluster/taskgraph/target_tasks.py`.
- removed existing filters against `ccov, windows10-aarch64` and `android-hw` filters against try syntax pushes.
- update imports for `fuzzy` and `chooser` selectors to refer to the new location of `filter_tasks_by_blacklist` method.
The reason for moving the logic (again) from `tools/tryselect` to `taskcluster/` is due to the placement of `try_option_syntax` and `target_tasks` files and both of those files handle the processing of `mach try syntax` pushes.

This commit:
- removes sendRpcMessage, which was unused;
- removes the CPOW argument to sendAsyncMessage, broadcastAsyncMessage, and
sendSyncMessage;
- removes the aIsSync argument used internally to distinguish sendRpcMessage
and sendSyncMessage;
- removes CPOW tests;
- updates the few remaining callsites that use more than 2 arguments in
sendAsyncMessage for the removal of the cpows argument.

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.

`ProfileBuffer` used to check if a `BlocksRingBuffer` was in session by looking
at its buffer size.
Now `IsInSession()` should be used, it is clearer in intent, and will make the
transition to `ProfileChunkedBuffer` slightly easier.

Changes:
- implement filtering of taskgraph items against a list of known task filters in `tasks.py`.
- apply these filters to both `fuzzy` and `chooser` selectors, unless `--full` is specified.

This commit removes `test_fix_stack_using_bpsyms.py`. That test can't easily be
modified to work with `fix_stacks.py` because it relies on internal
implementation details of `fix_stack_using_bpsym.py`. The unit testing done in
the `fix-stacks` repo provides test coverage that is as good or better.
