Bug 1894412 - When reading /etc/os-release, fall back to BUILD_ID when VERSION_ID is not set.  a=dmeehan

Arch Linux doesn't come with a VERSION_ID at all, but it has a BUILD_ID.
Semantically, falling back to BUILD_ID when VERSION_ID is not present
would seem fair play:

Per https://www.freedesktop.org/software/systemd/man/latest/os-release.html:

BUILD_ID=
    A string uniquely identifying the system image originally used as the
    installation base. In most cases, VERSION_ID or IMAGE_ID+IMAGE_VERSION
    are updated when the entire system image is replaced during an update.
    BUILD_ID may be used in distributions where the original installation
    image version is important: VERSION_ID would change during incremental
    system updates, but BUILD_ID would not. This field is optional.

Bug 1884962 - report kProtectionHDCP for the protection mask. r=media-playback-reviewers,padenot, a=dmeehan

According to what Widevine told us, `kProtectionNone` will cause playback
to stop if HDCP_V1 is required. Therefore, we would report HDCP protection
if there is no potential capturing.

Bug 1886892 - Part 2: (ESR115) Remove non-SHIP cases from SessionStore tests, r=#sessionstore-reviewers, a=dmeehan


These cases will no longer be run, as SHIP is always on for desktop firefox, so
can be removed.

Bug 1886892 - Part 1: (ESR115) Remove non-SHIP code from desktop SessionStore, r=#sessionstore-reviewers, a=dmeehan


In bug 1804140, we shipped SHIP everywhere on desktop. Unfortunately, we
never removed the now-dead code from SessionStore.

This patch removes the easy to identify SessionStore code for non-SHIP,
now that it is a fully unsupported configuration.

The only tab attribute which is ever persisted by SessionStore is
"customizemode". This patch limits the logic to only allow persisting and
restoring this attribute.

The browser_attributes.js test is also updated to use the "customizemode"
attribute for testing, rather than a custom specified attribute.

Minor test fix for ESR115.

Bug 1890514: Null-check 'view' before using it, in nsTreeBodyFrame::RemoveImageCacheEntry.  a=dmeehan

If it's null, we'll now just take the existing something-failed early-return codepath.

The 'view' local variable here is really just an alias for mView, and we have
null-checks for mView elsewhere, so it's conceivable that it could be null when
we get to this point. (And we have a low but nonzero level of crash volume for
folks hitting a null-deref on this line, which seems to confirm that it is
occasionally null here.)

I'm not including a test since I'm not sure how to trigger the conditions
required to crash in this way.  But the change is pretty trivial and clearly
a step in the direction of safety-against-crashing.

The only tab attribute which is ever persisted by SessionStore is
"customizemode". This patch limits the logic to only allow persisting and
restoring this attribute.

Bug 1878199 - patch 2 - If the FontFaceImpl has a user-font entry, hold its lock during Add/Remove font-set operations.  a=dmeehan

This should fix the intermittently-reported race here, by ensuring that access into
the FontFaceImpl from GetUserFontSets(), called by the main thread, cannot race with
changes being made by the AddFontSet()/RemoveFontSet() methods.

(If the FontFaceImpl doesn't have an mUserFontEntry yet, then these methods don't
need to lock, as only the owning thread will be touching it.)

Bug 1878199 - patch 1 - Don't create an additional Mutex in FontFaceImpl::Entry, just use the base gfxFontEntry's existing RWLock.  a=dmeehan

No functional change here, just cleanup in preparation for the following patch.
We don't need FontFaceImpl to create a mutex, as there's already a lock (RWLock)
in its base class gfxFontEntry, and we can use that to guard the fields here.

When a background page and service_worker are specified simultaneously,
load the background page instead of neither (i.e. the bug).

This patch only fixes the issue when
extensions.backgroundServiceWorker.enabled is false; When true, the
service worker is expected to load but doesn't due to
https://bugzilla.mozilla.org/show_bug.cgi?id=1775618#c1 . That requires
a different fix and is therefore saved for a follow-up.
