As mentioned in bug 1747354, the location of the dist directory is
relied to be $topobjdir/dist, so just use that consistently rather
than getting it from a separate variable for rust build scripts.

Bug 1744025 - Adding FetchEvent.mHandled FetchEvent.mPreloadResponse into CycleCollection checking. r=dom-worker-reviewers,smaug

Since these promises are also holding the GlobalObject(ServiceWorkerGlobalScope), they are needed to be added into the CycleCollection checking.
Otherwise, ServiceWorkerGlobalScope can not be unrooted as expected.

The test was failing in some case because interactiveEvent and completeEvent had
the same timestamp (which is still valid).
The test is modified to check greater or equal instead of strict greater.
Note that this test still has intermittent around willNavigateEvent and
loadingEvent (see https://searchfox.org/mozilla-central/rev/a2c26b9b49a521f4be39559ca1ca9c345a237c70/devtools/server/actors/webconsole/listeners/document-events.js#11-34)

Bug 1724385 [Linux] Try to create EGLImage over decoded VA-API video frame r=alwu,emilio,media-playback-reviewers

Differential Revision: https://phabricator.services.mozilla.com/D135460

Recently DMABuf modifiers are not correctly implemented for YUV surfaces - when a modifier is present we use it
for all planes to create EGLImage.
In this patch we import modifiers for all used YUV planes and use them correctly for particular planes.

Change some less important debugs to verbose so that we can use DEBUG level to focus more important things.

For AudioTrimmer, this will help to reduce huge useless logs if audio doesn't need to be trimmed.

Bug 1713276 - part1 : allocate shmem for ffmpeg to store decoded data directly. r=stransky,gfx-reviewers,sotaro,jgilbert,media-playback-reviewers

This implements a customized buffer allocator for ffmpeg decoder to allow it to store decoded data on shmem, so decoded data can be shared with the compositor process without doing extra copy.

As ffmpeg decoder needs a special alignment which will be larger than the actual image, we would need to crop the planes by telling plane descriptor correct place size in order to display image correctly.

Otherwise, showing a larger image causes visible incorrect border on the right and bottom of the actual image.

This will help improve the performance of software decoding while using ffmpeg and ffvpx, which is about h264 and vpx on Linux, vpx on Windows and MacOS.

Inaddition, Here is a result [1] showing that how much improvement using shmem can help.

Bug 1750588 - Make `AutoBlockElementsJoiner` handle deletion even when there is no ancestor block element of start or end range boundary r=m_kato

`HTMLEditor` assumes that inline elements cannot have block elements.  However,
it's not so if it's created by DOM APIs like `Node.appendChild` or making a
custom element an editing host.

Therefore, it's not unexpected case that only start or end of a range does not
have a block ancestor element.  So this patch makes `AutoBlockElementsJoiner`
not stop handling the deletion in the case.

Our platform-specific `bootstrap` code transitively depends on
the standard library's `distutils` module, but Debian Linux and derived
distros generally split `distutils` into a separate installable OS
package from `python3` itself.

So, Python 3 being able to run isn't a sufficient guarantee that
`distutils` is available.

To catch this case, add a `distutils` check at the very beginning of
Mach initialization.

-----

Also remove an obsolete comment claiming that `mach bootstrap` doesn't
need `distutils`, which was obsoleted by Bug 1717051.
