Similar to lines (see previous patch), floats from next-in-flow or overflow
frames have probably not been marked dirty (as ReflowInput hasn't dealt with
them when it was constructed), so we need to mark them dirty for proper reflow.
If we don't do that, and they don't fit in the current column, the next column
will only mark its current children dirty, so when pulling back its first
floats from the previous column they will not be reflowed as needed.

The front end code can't always guarantee to give us an allow/cancel response
to a permission request. In particular in these cases:
* if we close a tab while showing a doorhanger, or
* if we navigate a tab while showing a doorhanger, or
* if the permission prompt requested in a background tab and never shown.
Handling all of these cases is problematic; we don't get events for all of
these where it's easy and cheap to determine that we should cancel the
permission request.
Canceling the permission request is important in the autoplay-media permission
request case as there's objects waiting on the resolution of the permission
request, and they leak in ASan builds while running chrome tests if the Gecko
size of the permission request doesn't get a notification telling it to stop
waiting.
But we can however rely on the doorhanger code to drop its reference to the
nsIContentPermissionRequest object that we pass to it when the doorhanger goes
away. So we can cancel the permission request in our
nsIContentPermissionRequest's implementation's destructor in order to easily
catch all the above cases.
In order to do that, we need to split AutoplayRequest into two; one part being
the implementation of nsIContentPermissionRequest (AutoplayPermissionRequest),
and the other part being the code to own the PromiseHolder and manage the
permission request (AutoplayPermissionManager).
AutoplayPermissionRequest keeps a weak reference to AutoplayPermissionManager,
so that it can tell the AutoplayPermissionManager to reject the request promise
when it's destroyed.
This fixes the ASan leak for which I got backed out from earlier in this bug,
and also fixes the cases above.

(This patch was first presented for review in bug 1463919, I've split it off
into its own bug here).
If the user opens a tab in the background, and that tab tries to play media,
we'll delay playing that media until the tab is brought to the foreground.
But the user can explicitly start playback of such delayed media by clicking
the "play" icon we show in the tab indicator. Then if autoplay is disabled,
we'll block the play (unless the origin is whitelisted). This is bad, as the
user has clearly indicated intent to play media in this tab.
So this patch "gesture activates" the root content document when the tab audio
indicator play button is pressed. This means the block autoplay logic will
behave as if there's been a user gesture in the tab (mouse click or keypress),
and not block the play. Gesture activation state is per document, so it does
not persist across document loads.

1. we can avoid the memory mapped -shm files in wal mode
2. we gain more compatibility with nfs shares
3. we gain some protection from third parties touching open dbs

This uses the same event handling as the "listbox" and "listitem-checkbox" bindings that are scheduled for removal, and copies the required styles locally.
There is no need to preserve the scroll position explicitly anymore, because "richlistbox" handles scrolling like regular elements, and we don't want to persist the position when the selector is closed and reopened.

LSBUtils closes a file descriptor twice, once with fclose and then again with
close. It also does this on a background thread, during startup, which means
it tends to race with main thread code which opens files.
This patch fixes that, and also removes a work-around for the issue in the
MemMapSnapshot code.

The preference storage in the shared memory snapshot is much more compact than
the dynamic hashtable, and is already mapped in memory, so there's no need to
keep the full hashtable in memory in the parent process after the snapshot is
created.
This patch empties the hashtable and the name string arena after the snapshot.
It also removes the accounting for preferences which have changed after init,
since those are, by definition, exactly the set of entries in the dynamic
hashtable.

With the parent sending a snapshot of its preference state at content process
startup, we're guaranteed to have the full set of built-in preferences in the
shared map at initialization time, so there's no need to load them again.
This also applies to static preference default values, so we skip setting
those, as well.
However, we do need to make sure that we update static preference cache
entries whose default values don't match the value in the shared map, since
they may have been changed by user preference files. In order to deal with
that, we iterate over all preferences in the map, and dispatch callbacks for
any that have user values.

This patch changes our preference look-up behavior to first check the dynamic
hashtable, and then fall back to the shared map.
In order for this to work, we need to make several other changes as well:
- Attempts to modify a preference that only exists in the shared table
requires that we copy it to the dynamic table, and change the value of the
new entry.
- Attempts to clear a user preference with no default value, but which also
exists in the shared map, requires that we keep an entry in the dynamic
table to mask the shared entry. To make this work, we change the type of
these entries to None, and ignore them during look-ups and iteration.
- Iteration needs to take both hashtables into consideration. The
serialization iterator for changed preferences only needs to care about
dynamic values, so it remains unchanged. Most of the others need to use
PrefsIter() instead.

Since lookups in the snapshotted hashtable are currently O(log n) rather than
O(1), they're expected to be slightly more expensive than the previous
purely-dynamic lookups.
In general, I expect this not to be a major issue. The main concern is pref
cache lookups while initializing the database. Initialization in the parent
process will still always use only a dynamic hashtable, so the performance
characteristics there won't change.
In the child process, though, we'll still need to notify observers of
preferences in the snapshot when they have user values, which could require
any number of lookups at startup (though in practice probably will not).
This patch solves that problem by caching the wrapper for the current known
preference value when dispatching callbacks, and optimizing lookups for that
value when it is present.

For memory efficiency in content processes, we need to be able to store
changed preferences in a separate dynamic hashtable when their values don't
match the snapshot values.
That makes iteration over the full set of preferences somewhat more
complicated, since not only do we need to iterate over two tables, but we also
need to ignore preferences in the snapshot table if they also exist in the
dynamic hashtable.
This patch solves that problem by adding an iterator helper which iterates
over values in both tables, and skips values in the static table if they also
exist in the dynamic table.
In order to support completely deleting preferences that exist in the base
table, it also ignores all dynamic entries with the None type, so that they
can completely mask deleted base table values.
