MOZ_WEBRENDER=0 now does nothing -- you will either get HW-WR or SW-WR
depending on the platform configuration. The pref
gfx.webrender.force-legacy-layers is removed. This leaves no
configuration option to disable WebRender.
MOZ_WEBRENDER=1 will continue to force WR on, which will ensure in CI we
get HW-WR unless gfx.webrender.software is true.

Chrome has removed 3DES completely[0], but we're still seeing some uses of it
in telemetry. Our assumption is that this is either due to old devices that
can't be upgraded, and hence probably use TLS 1.0, or servers that bafflingly
choose 3DES when there are other, better, ciphersuites in common.
This patch allows 3DES to only be enabled when deprecated versions of TLS are
enabled. This should protect users against the latter case (where 3DES is
unnecessary) while allowing them to use it in the former case (where it may be
necessary).
NB: The only 3DES ciphersuite gecko makes possible to enable is
TLS_RSA_WITH_3DES_EDE_CBC_SHA. This patch also changes the preference
corresponding to this ciphersuite from "security.ssl3.rsa_des_ede3_sha" to
"security.ssl3.deprecated.rsa_des_ede3_sha".

This change makes all browsers which were not created with an initial `remote`
attribute within a non-`useRemoteTabs` window be unable to process-switch, as
otherwise we may attempt to switch loads into a content process. We need to
keep process switching enabled for explicitly-remote browsers loaded in a
non-`useRemoteTabs` window as it's relied on for tests and can lead to
assertion failures due to loading remote content in the parent process.

This load was causing a process switch after the changes in this patch.
This caused the view-source load to also process-switch back when loaded
and confused some view-source machinery. The load isn't necessary, and
if skipped the process switch due to navigation will not occur.

The changes in the previous part had a few behaviour changes which are visible
in tests, including cross-origin iframes with sandboxed origins now loading
remotely, and process selection for chrome-triggered null principal loads
behaving differently. In general this caused more process switches.

After the changes in this bug, about:blank loads triggered by chrome will
finish in a "web" content process, as they have an untrusted null principal
without a precursor. In a few places throughout the codebase, however, we
perform about:blank loads with the explicit expectation that they do not change
processes. This new remoteTypeOverride option allows the intended final process
to be explicitly specified in this situation.
For security & simplicity reasons, this new attribute is limited to only be
usable on system-principal triggered loads of about:blank in toplevel browsing
contexts.

CheckCurrentWord on content process causes sync IPC, so I would like to remove
this call on content process. New nsIEditorSpellChecker.suggest method can
avoid it.

The bug was that the tooltip was only being shown for reader-mode-button-icon. The tooltip would show if you hovered right over the icon, and it would be undefined otherwise. This patch shows the tooltip regardless of the hover target. The other items on nodeToTooltipMap and nodeToShortcutMap are toolbarbuttons, so their icons are added in CSS and event handling always sees the parent node as the hover target. The reader mode button icon, however, is an <image> child of its parent. Either it or its parent could be hover targets. I considered added some handling in GetDynamicShortcutTooltipText along the lines of checking node.closest(reader-mode-button). I settled on just adding more entries to nodeToTooltipMap and nodeToShortcutMap since it's safer and easier to uplift.

The CSS class panel-subview-footer-button was removed from the BMB_bookmarksShowAll
element in the Bookmarks Menu toolbar button, but this class is used by browser-places.js
to know where to insert the user's bookmarks in the structure of the menu.
Since this is the only menu that attachPlacesView attaches to, we can supply
the ID of the bottom Manage Bookmarks element, which will cause browserPlacesView.js
to insert the user's bookmarks above it.
