This just spins the event loop during fast shutdown until all queued
cert_storage tasks have completed. The patch achieves this by simply
adding a counter which will be incremented and decremented on the
main thread via tying into the tasks' `new` and `done` methods. A
slightly more performant solution would use a condvar and sleep the
main thread waiting on pending operations to complete, but given the
low frequency of these occuring during shutdown, such an approach
would be overkill.

We were storing LogModule::mName as an &'static str in the map... That's
not fine.
The Arc shenanigans were also more complicated than they need to be IMO.
This uses a plain atomic bool to keep the fast path snappy.

On mobile platform, "ENTER" key on software keyboard key can sometimes
change to "Next" and etc. Although Firefox OS/Firefox Android have
`mozactionhint` attribute for its behaviour, This is standardized version
of it.
Chrome and Safari already support it now, so I would like to support this
on Firefox/GeckoView Nightly.

This will allow to remove AbstractThread::Current() as GetCurrentSerialEventTarget TLS value will be set whenever a task dispatched on the XPCOMThreadWrapper is run.
Differential Revision: https://phabricator.services.mozilla.com/D80355
Before P1, GetCurrentThreadSerialEventTarget would have always returned the same data as NS_GetCurrentThread, making the comment incorrect Now it will properly return the running TaskQueue if any.
This change of name more clearly exposes what they are doing, as we aren't always dealing with threads directly; but a nsISerialEventTarget
Differential Revision: https://phabricator.services.mozilla.com/D80354
In the future, we may want to extend GetCurrentThreadSerialEventTarget to return the actual nsISerialEventTarget used to dispatch the task.

The crash reports indicate a situation where a non-default heap is destroyed
after we retrieve a handle is happening on a regular basis.
We've decided to count only the default heap, ignoring all non-default heaps
which we don't manage.

When TaskQueue was first conceived; it was only used with AbstractThreads and with tail dispatch.
By default, AbstractThread::Dispatch dropped the flags , as it was dispatching all tasks via the tail dispatcher.
It was an oversight, there's no use-case where we wouldn't want the dispatch flags to be carried forward.
It also simplifies the code and TaskQueue's use.

We have a clang-plugin check that wants to prefer `SprintfLiteral` over `snprintf`, but for some reason this wasn't caught before clang-11. I _think_ it has to do with previous versions not being able to see that `buflen` was constant, but I'm not really sure.

This also extracts new private member functions AssignOwned and AssignNonDependent.
Furthermore, it fixes an inconsistency for the dependent case: Formerly,
this caused the substring tuple to be materialized into a linear string
infallibly, although the function was a fallible one. It only assigned the
resulting string fallibly, but this would never have failed, since the
allocation already happened before.

Caching filenames in 32-entry LRU array covers >95% of calls, and makes the average `Filename()` call 5 to 10 times cheaper.
browser_start_content_mainthreadio.js needed to be updated to handle operations that now have a filename thanks to the cache.

This removes variants of "blacklist" from the xpcom directory. The preference name "network.file.path_blacklist" is left in place and will need a more thorough plan for removal. Instances of `MOZ_ASAN_BLACKLIST` remain as well and should be replaced in a larger modifcation of the `#define` in the mfbt component.

mozilla::ReverseIterator is required for "stashing iterators", but otherwise
std::reverse_iterator can be used and is potentially more efficient.
Also fix some other glitches in iterator type definitions.
