This is a backout of Bug 1347791 part 4; 49b533231388.
49b533231388 took the mediaBlocked attribute and stored it in session store,
and caused us to call browser.resumeMedia() or blockMedia() as appropriate
upon restore. We don't want to session restore whether tabs have had delay
playback start unblocked anymore, so remove the code that session stores
that attribute.

Since we want to start collecting all form data through mapFrameTree on Fennec,
too, we need to change our filtering strategy for form data.
We can no longer bail out directly during the data collection loop and instead
have to filter the data after having collected all of it.
The easiest way to do that is to start using PrivacyFilter.filterFormData() on
Android as well.

NOTE: The '__SSi' and '__SS_lastSessionWindowID' properties on windows are kept,
because they are expected to stick around longer during application shutdown.
The benefits is are:
1. Cleaner code - Sessionstore implementation details are not leaked outside its
module.
2. Observing the lifetime of objects becomes unnecessary, because the WeakMaps are
cleaned up when objects are GC'd, making leakage of their references impossible
and Sessionstore can't hold objects hostage anymore.
3. Simplification - all state is now maintained in SessionStore.jsm, which allows
for additional refactoring later on to simplify the implementation further.

This patch was autogenerated by my decomponents.py
It covers almost every file with the extension js, jsm, html, py,
xhtml, or xul.
It removes blank lines after removed lines, when the removed lines are
preceded by either blank lines or the start of a new block. The "start
of a new block" is defined fairly hackily: either the line starts with
//, ends with */, ends with {, <
