After user ticks the checkbox of allowing error reporting, we will
report the error through the telemetry event. The event includes the
error type, XFO policy, CSP policy, the frame uri and the top-level uri.

Update testing/mochitest/pywebsocket with the latest version available: pywebsocket3
is python 3 compatible. This keeps the basic structure of the old pywebsocket, but
changes the directory name to pywebsocket3 to reflect the project renaming.

Start/StopAudioCallbackTracing calls are always around locked_profiler_start/stop, this patch brings these calls inside the locked_ functions.

Profile buffer updates could be triggered from a number of locations, including scopes where profiler and/or system locks are held, making deadlocks possible if profiler and/or system function are called.
So instead of dispatching updates to the main thread (which may use OS task queue functions), we fold updates into a static storage. The profiler sampler loop regularly triggers processing of these pending updates.

Profile buffer updates could be triggered from a number of locations, including scopes where profiler and/or system locks are held, making deadlocks possible if profiler and/or system function are called.
So instead of dispatching updates to the main thread (which may use OS task queue functions), we fold updates into a static storage. When child updates arrive, we can safely handle parent updates as well.
Child updates are assumed to arrive regularly enough to properly handle parent updates.
But in the worst case, if no updates came from children, it should mean nothing is happening, and in any case we wouldn't know how the memory is used elsewhere. Note that the chunk manager still enforces local limits automatically, so memory usage would still get limited.

Knowing the time it takes for the parent process to gather its profile, we expect sub-processes not to take longer than twice that time (plus a bit more).
Each time we receive a profile, the timer is restarted* to allow more time for pending processes.
If the most current timer fires, we assume that pending processes may be frozen and unable to ever respond, so we use all profiles gathered so far.
(There is currently no indication to the user that processes are missing, this should be added in the future.)
* Tech detail: We just cancel the current timer and forget about it, then start a new one and keep track of it. When a timer fires, we can compare its address to the address of the last (most current) timer, and only that one can force the end of profile-gathering.

Try syntax users wishing to preserve their default selector can modify
~/.mozbuild/machrc (create it if it doesn't exist), and add:
[try]
default = syntax

Since partials have started verifying signatures, the partial task has been failing in
`mach try scriptworker`. Since we are not concerned with the partial task itself,
split the tasks into two groups, so that it does not need to run.

It is possible that some threads fail/forget to unregister themselves, in which case a registered thread id could get recycled by a later thread, which was not allowed before this patch.
Note: The thread name cannot currently be changed. We record a special marker with the new name, so the frontend could process it to split the thread track at that point.
We also record a marker when profiler_unregister_thread is called from an already-unregistered thread, this could help find reg/unreg mismatches or nesting in Firefox threads.

On Linux (including Android), it was assumed that a registered thread could always be suspended through `tgkill`.
However in some cases a thread may not be correctly unregistered, in which case this would trigger `MOZ_ASSERT` or wait forever in the following loop.
This will especially be needed when `profiler_{,un}register_thread()` are made less strict in the following patch.
Windows and Mac already handle suspension failures.
