Since NoFocusState is am empty struct used in the |mData| variant in
FocusTarget, we need to add a Reader and a Writer for IPC for NoFocusState so we
can properly read and write the |mData| variant. The NoFocusState Read and Write
methods do not read or write anything, since NoFocusState does not contain any
data. This is done by creating a helper class EmptyStructSerliazer and
inheritting from EmptyStructSerializer for the NoFocusState specialization.
The |Read| and |Write| methods for FocusTarget are updated by removing the read
and write code for the individual types of |mData| and instead makes use of the
IPC read and write methods for Variant.

It's important that shmem creation/destruction messages be ordered
correctly with respect to other messages that use shmems. For example,
if we create a shmem with ID 10 and then send a message that
references shmem 10, then the creation message must be handled before
the referencing message. If shmem creation/destruction messages go in
a separate queue from other messages, this ordering may not be
preserved.
Leaving shmem creation/destruction unlabeled will give us the correct
ordering. Eventually, though, we'll need to provide a solution that
doesn't bottleneck the event queue.

The WebRequest API needs to know if a given window ID is at the top level, for
various reasons. It currently figures this out by mapping a channel's load
context to a <browser> element, which tracks its current top outer window ID.
But this is inefficient, and not friendly to C++ callers.
Adding the top window ID to the load info simplifies things considerably.

Certain types (such as Shmem and Endpoint types) cannot be copied, and need to
be moved when passed around. When used with MozPromises, that means that the
promise needs to be non-shareable, and the resolve functions need to use the

This interface will allow extensions running into a content process to attach
a filtering stream listener to an HTTP request in the parent process. The
content process attaches a listener by sending a message from the content
process containing the ID of the request to filter, and the ID of the add-on
making the request. The permissions and request mappings for this are handled
by the web request service added in part 2.

Bug 1360308 offloads IO operations from the main thread when we create paired minidumps.
This breaks the symmetry of paired minidumps: the thread stacks of the parent minidump
doesn't correspond to the thread stacks in the child minidumps and renders the parent
stack useless. This patch moves generation of the parent minidump back to the main
thread to keep the context of the parent process when creating paired minidumps. Child
minidump is still created asynchronously.

When removing our Windows message loop pumping code in the content
process, a11y code on the MTA thread must have some way to wake up the
main thread. The main thread could be blocked either on a conditional
variable waiting for a Gecko event, or it could be blocked waiting on
a Windows HANDLE in IPC code (doing a sync message send). In the
former case, we wake it up by posting an event to the main thread. In
the latter case, we continue to use the asynchronous procedure call
mechanism.

There are two problems related with EVENT__SIZEOF_OFF_T:
- When building Firefox with -D_FILE_OFFSET_BITS=64, off_t is 64 bits,
but the in-tree event-config.h still defines EVENT__SIZEOF_OFF_T to 4.
- When building Firefox *without* -D_FILE_OFFSET_BITS=64 (the default)
against a system libevent that was built with -D_FILE_OFFSET_BITS=64,
its event-config.h defines EVENT__SIZEOF_OFF_T to 8, which then
doesn't match off_t size.
For the latter, libevent actually defines its own off_t type, that
callers are supposed to use instead of off_t. So that's what our
static_assert should be checking.

Having these functions declared in the class definition and therefore
inlined means that every call site is bloated by having to store the
argument so its address can be taken and load the sizeof() constant.
There's no good reason that we should be doing this; the Read*
counterparts are also out-of-lined, which hasn't seemed to cause any
problems. Moving these out-of-line saves about 200K (!) of space on
x86-64 Linux.
nsIURI.originCharset had two use cases:
1) Dealing with the spec-incompliant feature of escapes in the hash
(reference) part of the URL.
2) For UI display of non-UTF-8 URLs.
For hash part handling, we use the document charset instead. For pretty
display of query strings on legacy-encoded pages, we no longer care to them
(see bug 817374 comment 18).
Also, the URL Standard has no concept of "origin charset". This patch
removes nsIURI.originCharset for reducing complexity and spec compliance.

Previously we used the base::StatisticsRecorder object for storage by name.
This is keyed by histogram name, which doesn't match our storage reality anymore.
Instead we use a name to refer to a set of histogram instances that record data from different processes, as well as separating session and subsession data.
In this re-write, we instead introduce the following lookup paths (managed in TelemetryHistogram.cpp):
- Main storage:
- (histogramId, processId, sessionOrSubsession) -> Histogram*
- (histogramId, processId) -> KeyedHistogram* (this handles subsessions internally)
- Lookup:
- (histogramName) -> histogramId
- (HistogramID) -> bool (is recording enabled for this histogram?)
This is wrapped with a few lookup functions.
This also allows us to keep HistogramIDs in the JS histogram instances now, instead of pointers to Histogram instances.
That means Histogram instance life-time management is now properly contained inside TelemetryHistogram.cpp.

Focus can change at any moment in a document. This causes non-determinism and
correctness problems for doing keyboard apz scrolling. To get around this, we
will maintain deterministic behavior for focus changes initiated by input events
and see if we can get away with more non-determinism for things like `setTimeout`
In order to do this, we disable async keyboard scrolling when an input event is
processed that could have a event listener. We then attach a sequence number to
that input event and dispatch it to content. In content, we record the highest
sequence number that we have processed from an event, and send that on each focus
update. Using this, we can determine in APZ if we have a current focus target or
if we are still waiting for an input event to be processed and focus to be
reconfirmed.
