With this patch on its own we get some a11y tests failures, but those
are fixed on a later patch.
Combobox select no longer creates frames for its <options>, nor an
nsListControlFrame. Instead, it computes its right intrinsic size using
the largest size of the options. This is better, because we render the
option text using the select style so if the select and option styles
are mismatched it'd cause changes in the size of the select when text
changes. See the following in a build without the patch, for example:
<select>
<option>ABC</option>
<option style="font-size: 1px">Something long</option>
</select>
This seems like a rather obscure case, but it's important to get it
right, see bug 1741888.
With this patch we use the same setup in content and parent processes
(this needs bug 1596852 and bug 1744152). This means we can remove a
bunch of the native view and popup code in nsListControlFrame. A couple
browser_* tests are affected by this change and have been tweaked
appropriately (the changes there are trivial).
Not creating an nsListControlFrame for dropdown select means that we
need to move a bunch of the event handling code from nsListControlFrame
to a common place that nsComboboxControlFrame can also use. That place
is HTMLSelectEventListener, and I think the setup is much nicer than
having the code intertwined with nsListControlFrame. It should be
relatively straight-forward to review, mostly moving code from one part
to another.
Another thing that we need to do in HTMLSelectEventListener that we
didn't use to do is listening for DOM mutations on the dropdown. Before,
we were relying on changes like text mutations triggering a reflow of
the listcontrolframe, which also triggered a reflow of the
comboboxcontrolframe, which in turn updated the text of the anonymous
content. Now we need to trigger that reflow manually.
There are some further simplifications that can be done after this
lands (cleanup naming of openInParentProcess and so on, among others),
but I'd rather land this first (after the merge of course) and work on
them separately.

Building with --disable-xul has been busted since _at least_ bug
1082579, for more than 7 years (I didn't try to track that down
further). It's time to recognize that the option serves no purpose.

I considered removing this class initially, but it's actually a pretty
useful abstraction over the DateTimeFormat interface when used
specifically with Gecko. It applies the OS preferences and provides some
caching behavior.

-Wshadow warnings are not enabled globally, so these -Wno-shadow suppressions have no effect. I had intended to enable -Wshadow globally along with these suppressions in some directories (in bug 1272513), but that was blocked by other issues.
There are too many -Wshadow warnings (now over 2000) to realistically fix them all. We should remove all these unnecessary -Wno-shadow flags cluttering many moz.build files.

Automatically generated path that adds flag `REQUIRES_UNIFIED_BUILD = True` to `moz.build`
when the module governed by the build config file is not buildable outside on the unified environment.
This needs to be done in order to have a hybrid build system that adds the possibility of combing
unified build components with ones that are built outside of the unified eco system.

Instead of initializing on first use - which can race with workers - do the
initialization in nsLayoutStatics::Initialize(). Also make `sInShutdown` an
Atomic since it is accessed without locks.

This changes font-family storage to reuse the rust types, removing a
bunch of code while at it. This allows us to, for example, use a single
static font family for -moz-bullet and clone it, rather than creating a
lot of expensive copies.

This is a step towards separating the mutable state on principals from const
state which can be made threadsafe. The remaining mutable fields will either
need to be moved off of nsIPrincipal or made threadsafe to destroy (e.g. using
nsMainThreadPtrHandle) and stored behind a mutex.
Serialization is handled for most types using a separate Deserializer class,
like how it was handled with `nsIURI` mutators. SystemPrincipal wasn't changed
as the `Read` method is a no-op for that class.

This is necessary to remove the Init methods from principals, allowing
immutable fields to be marked as const and clearly separated from mutable
fields to improve threadsafety.

There's no reason we can't just query LookAndFeel and we need to use
sSystemMetrics. In the past, LookAndFeel queries were not cached, but
this is no longer the case, so perf wise should be pretty equivalent.
Note that we don't need the NS_SUCCEEDED checks because the default
value from GetInt if the platform doesn't support it is 0 anyways.

Implement an observer to wait for correct window events in order to restore tab
content. Non-SHIP code restores about:reader scroll position after receiving
"AboutReaderContentReady" event, so to achieve the same thing with session
history in parent enabled, we can wait for "AboutReader:Ready" event.

The SpinEventLoopUntilOrShutdown is interrupted in the main process only at stage "xpcom-shutdown", which is too late. In a content process instead we interrupt it early enough, at "content-child-will-shutdown".
This patch removes the current observer logic in nsThreadManager in favor of a current shutdown phase state machinery in AppShutdown and renames SpinEventLoopUntilOrShutdown to SpinEventLoopUntilOrQuit. It also ensures that SpinEventLoopUntilOrQuit breaks early (at "quit-application" in the main process).
For a further possible cleanup around shutdown state in child and parent process please refer to bug 1697745.
We have no automated test for this edge case, but we have diagnostic telemetry that will tell us if it helps.

Previously we were initializing IOUtils lazily when we received our first IO
request, but that could run into problems when
1. shutdown starts before submitting any IO requests, which would then fail to
add shutdown blockers for phases we have already passed; or
2. the first IO request comes from off-main-thread, which can not tell if the
shutdown blockers are added successfully.
Now we register an observer to initialize the event queue and add all startup
blockers in the `profile-after-change` phase. We can then be sure that IOUtils
will have its blockers added before `profile-before-change`.

These services had their name added to components.conf:
* GfxInfo
* ThirdPartyUtil
* History
* HttpActivityDistributor
* UUIDGenerator
* ServiceWorkerManager
* PermissionManager
These services were added to componenets.conf under a different name:
* DirectoryService => Directory
* IOService => IO
* StringBundleService => StringBundle
* CacheStorageService => CacheStorage
* StreamTransportService => StreamTransport
* SocketTransportService => SocketTransport
These services weren't migrated to components.conf because only Rust
code uses them:
* RemoteAgent
* XULRuntime
* PrefService
These services weren't migrated to components.conf because they're unused:
* ToolkitChromeRegistry (used as ChromeRegistry)
* XULChromeRegistry (used as ChromeRegistry)
* Bits (completely unused)
These services were already available in components.conf but are still
used by rust code:
* URIFixup
These services weren't migrated because they will be handled in
subsequent patchsets:
* ObserverService
For the record, the following Services are being used by Rust code
and must remain until a Rust version of Components.h is written:
* RemoteAgent
* XULRuntime
* PrefService
* URIFixup
* ObserverService
* DirectoryService
* ThirdPartyUtil
Also the cocoa GfxInfo service was changed to use components.conf instead
of registering it at runtime, as all the other widgets were already doing
it this way.
