In our autoplay shield-study, we want to collect the information which could tell us how many website
contains audible autoplay media, but there is no way to get this information on current API desigin.
Therefore, I would like to send a new notification when autoplay occurred.
The extension code could get the information by following way,
```
Services.obs.addObserver((subject, topic, data) => {
// DO SOMETHING
}, "AudibleAutoplayMediaOccurred");
```

(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.

Since we're naming this new file as DateTimePickerContent, it's also a good opportunity to rename the DateTimePickerHelper to DateTimePickerParent to make it more meaningful

This is a partial backout of Bug 1347791 part 3; a5fbb7e2d1d0.
a5fbb7e2d1d0 added a mediaBlocked attribute to the browser element, which
tracked whether the tab has ever been in the foreground, so that this could
be saved and restored in session restore. We don't session restore this
anymore, so we can remove this attribute and associated event handlers.
This also removes the media.autoplay* pref accesses which are accounted for in
the test browser_preferencecs_usage.js, so remove those prefs from that test.

This also removes any redundant Ci.nsISupports elements in the interface
lists.
This was done using the following script:

This patch renders error message for the Simplify Page document when
Reader Mode fails to parse original document. This patch also adds a test
to reliably produce a readable document that returns a parsing error when
run through the readability library.

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 {, <![CDATA[, """ or '''. The first two
cover comments, the third one covers JS, the fourth covers JS embedded
in XUL, and the final two cover JS embedded in Python. This also
applies if the removed line was the first line of the file.
It covers the pattern matching cases like "var {classes: Cc,
interfaces: Ci, utils: Cu, results: Cr} = Components;". It'll remove
the entire thing if they are all either Ci, Cr, Cc or Cu, or it will
remove the appropriate ones and leave the residue behind. If there's
only one behind, then it will turn it into a normal, non-pattern
matching variable definition. (For instance, "const { classes: Cc,
Constructor: CC, interfaces: Ci, utils: Cu } = Components" becomes
"const CC = Components.Constructor".)

Adding <meta name="viewport" content="width=device-width"/> to the view-source
document achieves two things when used in a mobile browser, such as Fennec:
1. When word-wrapping is turned off, the page displays at a more readable
initial zoom level.
2. As of now, font inflation (when enabled) kicks in on the document when word-
wrapping is turned on, which leads to the line numbers appearing in a
noticeably smaller font size than the rest of the page.
Adding the above meta viewport header marks the document as "mobile-friendly"
and suppresses font inflation, which means that line numbers will appear
normally even with word-wrapping enabled.
getMathMLSelection() in browser-content.js isn't actually used in Fennec at the
moment, but for consistency we add the meta viewport tag there as well.
