Bug 1376000: Drop any unknown flags in SinkInfo.flags. r?padenot Rust expect() is bad in C callbacks. Replace TryFrom() with from_bits_truncate() to drop any unknown PulseAudio flags. MozReview-Commit-ID: 4RWFB5iGW6Z

Bug 1373213 - Repair cubeb logging when using env var. r?jesup This does two things: - Stop calling the callback when initializing cubeb prefs callback, see the comment block for the rationale. - Change the pref name so that the problem does not continue to be triggered with users that have the old pref name in their profile.

Bug 1370007 Generate Shaders on a MinGW Cross Compile on Linux Bug 1365859 introduced a dependency on the Visual Studio binary 'fxc' to generate Shader bytecode. This was unavailable when compiling for Windows on Linux as part of a MinGW build. This commit adds a configure check for fxc, and also searches for fxc2, which was written (https://github.com/tomrittervg/fxc2) to be a tiny application that wraps D3DCompileFromFile and can produce similar (but not exactly the same) output as fxc. fxc2 is compiled using MinGW for Windows, and runs under wine, so we need to check for wine also. Finally, fxc outputs some include information fxc2 doesn't, so we will just change that assert to not take effect. MozReview-Commit-ID: 8LVxuODi6cV

Bug 1375930: Fix rem computation on the root element. r?heycam I'll be really pissed off if this doesn't make any new test pass and I have to write one... I don't actually know how could we get this so wrong for so long... MozReview-Commit-ID: DK98SS1w5nO

bug 1366294 - Part 8 - Include a message on telemetry testfails. r?gfritzsche I just added some short identifiable messages to help identify which part of the test failed. MozReview-Commit-ID: 3AX2iucGiRx

bug 1366294 - Part 7 - Use keyed histogram snaphots to build payloads. r?gfritzsche TelemetrySession's getKeyedHistograms asks for each keyed histogram individually. This is inefficient and doesn't work well with the storage refactor. So, plumb through a subsession keyed histogram snapshot API and convert TelemetrySession over to using it.

bug 1366294 - Part 6 - Update test_TelemetryHistograms for new snapshots format r?gfritzsche MozReview-Commit-ID: FN6y1zTqFt4

bug 1366294 - Part 5 - Send appropriately-structured Telemetry data to JS r?gfritzsche Previously we were doing bad string manipulation nonsense. Now when asked for snapshots C++ can return a properly-formated Object tree. MozReview-Commit-ID: HAvIbgzUvMU

bug 1366294 - Part 4 - Small cleanups to previous patches. r?gfritzsche MozReview-Commit-ID: 7PioVNfUUNZ

Bug 1366294 - Part 3 - Refactor TelemetryHistogram storage. r=chutten Previously we used the base::StatisticsRecorder object for storage by name. This is keyed by histogram name, which doesn't match our storage reality anymore. Instead we use a name to refer to a set of histogram instances that record data from different processes, as well as separating session and subsession data. In this re-write, we instead introduce the following lookup paths (managed in TelemetryHistogram.cpp): - Main storage: - (histogramId, processId, sessionOrSubsession) -> Histogram* - (histogramId, processId) -> KeyedHistogram* (this handles subsessions internally) - Lookup: - (histogramName) -> histogramId - (HistogramID) -> bool (is recording enabled for this histogram?) This is wrapped with a few lookup functions. This also allows us to keep HistogramIDs in the JS histogram instances now, instead of pointers to Histogram instances. That means Histogram instance life-time management is now properly contained inside TelemetryHistogram.cpp. MozReview-Commit-ID: 5yijGv7mc89
