This patch addresses an issue with Firefox's proxy detection on networks which
do not have their a proxy auto-configuration (PAC) file hosted at
http://wpad/wpad.dat, and instead make use of DHCP option 252 for broadcasting
the address of the PAC file. See https://findproxyforurl.com/wpad-introduction/
for an introduction to the protocol.
Prior to this patch, proxy auto-detect missed out the DHCP query stage, and just
looked for a PAC file at http://wpad/wpad.dat
This patch only addresses the issue for Firefox on Windows, although it defines a
DHCP client interface which could be implemented on other platforms.
The high-level components of this patch are:
* nsIDHCPClient.idl - this is an interface which has been defined for querying the
DHCP server.
* nsPACMan.cpp - where previously when the PAC URL was simply set to a constant of
http://wpad/wpad.dat, it now dispatches an asynchronous command to the proxy
thread. The class ExecutePACThreadAction has been augmented to include an
instruction to 'ConfigureWPAD' (Configure Web-proxy auto-detect), and a new class,
'ConfigureWPADComplete' has been created to relay the result (the URL of the PAC
file) back to the nsPACMan object.
* nsProtocolProxyService.cpp
Minor changes to reflect the fact that the PAC URL not being set does not always
mean there is no PAC to be used; instead it could be in the process of being
detected.
* TestPACMan.cpp
This is a new file, and tests only the DHCP auto-detect functionality.
Some tests use multiple threads, as they test the non-blocking proxy detection.
* DHCPUtils.cpp
A class containing the main logic for querying DHCP.
* WindowsNetworkFunctionsWrapper.cpp
A very thin wrapper around the Windows API calls needed by DHCPUtils.
This class was introduced so it could be mocked out in tests.
* nsWindowsDHCPClient.cpp
* An implementation of the interface defined in nsIDHCPClient.idl. Fairly thin:
most logic is implemented in DHCPUtils.
* TestDHCPUtils.cpp
Tests for DHCPUtils and nsWindowsDHCPClient

If we're showing a permission UI prompt for "autoplay-media", the user can
still actually play media without interacting with the doorhanger; if they
click a "play" button in the document, they'll "gesture activate" the document
and unblock autoplay and be able to start playback.
It doesn't make sense to keep showing the permission doorhanger to approve
autoplay when the page is already playing, as playback has already started, and
if they clicked on "block" then the site would receive a promise reject on the
promise returned on the first call to HTMLMediaElement.play() for which we were
showing the permission prompt for, even though the media is actually playing.
This will likely confuse JS video players.
So we should hide the permission prompt when playback in the page starts.

This patch:
* Exposes a global Sync change counter on `nsINavBookmarksService`.
This is similar to SQLite's `total_changes()`, but just for changes
to bookmarks that affect Sync, and accounts for changes from multiple
threads and connections.
* Adds a SQL function to bump the counter, and extends the
`moz_bookmarks` triggers to call it.
* Moves merging outside the transaction in the bookmarks mirror, and
checks that the counters match before applying.

Adding or removing an FD from this API currently requires changes in about a
half dozen places. Ignoring the Java side of things. This patch changes the
API to pass a struct, rather than additional arguments for each FD, so that
adding and removing FDs only requires changing one declaration, and the two
call sites that add and consume the FDs.

Add assertions to highlight what the various data structures
should look like.
Also assert to ensure that mIndexPrefixes is always the same
length as mIndexDeltas and avoid writing the prefixes to disk
if that's not the case.
Do a single fallible allocation before we create the indexStarts
array instead of checking on each AppendElement() to simplify
the loop and emphasize the number of elements that the array
will receive (indexSize + 1). Remove the last element since we
don't actually end up writing it to disk.

This simplifies the logic around clearing the prefix set and also adds
the clearing of the mIndexDeltasChecksum which should have been done
as part of 3a00711bb0e6.
Additionally, the checks for whether or not the prefix set is empty
include some sanity-checking asserts.
Finally, mTotalPrefixes could be out of sync with mIndexPrefixes
and mIndexDeltas if LoadPrefixes() or MakePrefixSet() fail so we
now only update it once all elements have been added successfully.
There is now a release assert to catch grossly out-of-sync (or
corrupt) values of mTotalPrefixes.

(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.

initialProcessData has the unfortunate side-effect of sending an entire copy
of all of its data to all content processes, and eagerly decoding it. For the
extension framework, this means that we wind up loading an entire copy of all
of our schema data, and of every extension's manifest and locale data, into
every process, even if we'll never need it.
The sharedData helper allows us to store an encoded copy of that data in a
shared memory region, and clone it into the current process only when we need
it, which can be a significant savings. For screenshots alone, it saves about
15K on locale and manifest data per content process, plus the size we save on
not copying schema data.
