Bug 1544105 added a default implementation of `GfxInfoBase::FindMonitors` so
`gfxInfo.getMonitors()` no longer throws on Linux, but it only ever returns the
primary monitor there.

When I implemented the no preview for span I did originally try using text in
the canvas, but discarded it when I realised trying to format it to display
nicely (across different languages and text lengths) was a losing proposition.
However just the prohibition symbol without context is confusing to users, and
on reflection the text can easily be included as an element stacked on top of
the canvas.
Also lighten the background of the no preview message, since the pure black was
indistinguishable from the frame sides on Windows and Linux.

when an instance is terminated while it is still running a task, the generic worker process exits with an interrupt exit code. this change treats such exit codes as an exception which triggers a task retry

When under pressure, the MediaCache evicts data before the last read on a
stream. We typically have two demuxers reading from different offsets in a
stream. So if the MediaCache is under pressure, it may end up evicting data
between the two demuxers.
The MediaDecoderStateMachine currently goes into buffering state if there's
insufficient data available beginning at the start of its queue of decoded
samples. However since the MediaCache evicts data behind the streams read
cursor, the data after the beginning of the sample queue may have already been
evicted by the media cache. This will cause the MediaDecoderStateMachine to
enter a buffering state, and if its sample queues are full, there will be no
demuxers reading to cause the MediaCache to download the data between the two
demuxers, and we'll get stuck in buffering state indefinitely.
So change the MediaDecoderStateMachine to instead check whether there's
insufficient data available at the end of the decoded sample queues. This means
we won't get stuck in buffering state. Note the MediaCache may still evict data
which the other demuxer needed, causing us to re-request it, but at least we
won't get stuck in buffering state.

Debugger::onSingleStep asserts that the script's step mode count is fully
accounted for by Debugger.Frame instances with onStep handlers. The existing
assertion only takes into account live Debugger.Frames --- it simply looks up
the current frame's AbstractFramePtr in existing Debuggers' frame maps. But
Debugger.Frames referring to suspended generator calls also contribute to the
generator's script's step mode count, and need to be included.

Normally, context menu keyboard handling takes precedence.
However, because we have a capturing window keydown listener, our listener takes precedence.
Therefore, we need to check for an open context menu and suppress our keyboard handling in this case.

We use `columnCount == aConfig.mBalanceColCount - 1` in other places to
determine if we are at the last column. Advancing the column count at
the end of the loop make the condition consistent.

In part 1, we disabled the unhooking of DLL-intercepted functions at shutdown. The TestDllInterceptor relied on unhooking -- it worked by hooking functions with a "nonsense function" (nullptr) and then immediately unhooking it. That restored the original function behavior. Some hooked functions (e.g. NtWriteFile) are used by functions later in the program (e.g. printf) so the functions need to maintain their behavior.
This patch replaces the nonsense function with an identity function that also sets a global boolean as a side-effect. The function is written in machine code. x86-32, x86-64, and aarch64 variants are included.

This patch fixes a static destructor order dependency between WindowsDllInterceptor and VMSharingPolicyUnique by telling VMSharingPolicyShared not to access the VMSharingPolicyUnique at destruction. This means that the behavior of intercepted functions is no longer restored in the given process at policy shutdown time.
