Bug 1430841 Refactor ReduceTimePrecision and add (failing) gtests r?bkelly This commit adds a gtest calling ReduceTimePrecision that illustrates several failing test cases from float fuzziness, as well as generating a ton of test cases at random that also fail. MozReview-Commit-ID: Epia5gm5Ahb

Bug 1433019 - Dispatch scroll events before dispatching animation events. r?mstange,botond See 7.6. in the section '8.1.4.2 Processing model'; https://html.spec.whatwg.org/multipage/webappapis.html#processing-model-8 Note that this dispatching scroll events should be done after we process WillRefresh() for FlushType::Style observers since main-thread scroll animations is one of the FlushType::Style observers, that means it affects scroll events. Also test_scroll_event_ordering.html was modified to check scroll events happen before requestAnimationFrame callbacks. MozReview-Commit-ID: LuV157XoRkJ

Bug 1428182 - 10. Add <malloc.h> include in pixman patch; r=lsalzman pixman-8888-over-565.patch added a call to free(), which is apparently not included by the other headers when using the new NDK headers. MozReview-Commit-ID: 9fAuSano36N

Bug 1428182 - 9. Apply Skia upstream commit to support NDK r16; r=lsalzman Apply Skia upstream commit 592c225b03ca677a1217eabdbc38eede6afcdb14 to support building with NDK r16. MozReview-Commit-ID: B6popOoPTni

Bug 1428182 - 8. Don't redefine keycodes when using unified headers; r=esawin The unified headers already define the keycodes in GeckoEditableSupport.cpp, so only define them ourselves when not using unified headers (by checking the __ANDROID_API_X__ macros). MozReview-Commit-ID: 3Ptakcm0rW

Bug 1428182 - 7. Include <link.h> in LUL for Android; r=jseward Modern NDK headers all have <link.h>, so we should always include it, and still provide shims for anything we need that's not defined in <link.h>. MozReview-Commit-ID: GNBDIe73RFm

Bug 1428182 - 6b. Support unified headers in Breakpad code; r=ted Fix several problems when building Breakpad with new NDK unified headers. - Unified headers define its own tgkill wrapper, so rename our own wrapper to __tgkill. - Unified headers define user_fpxregs_struct for all API levels, so don't redefine it. - Only the target sources under google-breakpad/src/common/linux should use custom Android headers, so change the includes line in moz.build to use OS_INCLUDES.

Bug 1428182 - 6a. Apply Breakpad upstream commit for building with NDK r16; r=ted Apply commit afa9c52715db1e4bfaa4b01c9aec40cc249b689b from the Breakpad upstream to support building with NDK r16. MozReview-Commit-ID: D6xafYkjhjt

Bug 1428182 - 5. Update libevent patch for Android builds; r=nfroyd Support for accept4 and arc4random_buf depends on which set of NDK headers we're using. accept4 is supported for API >= 21 for unified and non-unified headers. arc4random_buf is supported for API >= 21 if using non-unified headers, and it's always supported if using unified headers (the unified headers provide shims for API < 21).

Bug 1428182 - 3. Only include <linux/elf.h> for non-unified headers; r=glandium Unified headers have a complete <elf.h> so we should include that instead of <linux/elf.h>. MozReview-Commit-ID: DkQv2vk1Q62

Bug 1428182 - 2. Check both quota.h and quotactl(); r=glandium Android headers can have a <sys/quota.h> header but with its functions ifdef'ed out. Check for that by checking for the presence of quotactl(). MozReview-Commit-ID: 26ILnbP7flO

Bug 1428182 - 1. Support unified headers for Android builds; r=nalexander NDK headers are grouped into a "sysroot" directory, which doesn't contain architecture-specific bits, and a "system" directory, which contains only the architecture-specific bits. Previously, both directories are the same, under platforms/android-*/arch-*/. However, with unified headers in NDK r16, the two are different, so we need to support that in the Android build scripts. Unified headers also rely on the build system defining the __ANDROID_API__ macro, so we add support for that as well. MozReview-Commit-ID: 9zBNQC3BRFl

Bug 1433971 Clean up Assertions.h with respect to Unused Attributes r?froydnj In Bug 1393538 I renamed MOZ_STATIC_ASSERT_UNUSED_ATTRIBUTE to MOZ_UNUSED_ATTRIBUTE, moved it out of it's #define depth, and used it in toolkit. I also orphaned a comment. This was wrong. MOZ_UNUSED_ATTRIBUTE was basically identical to MOZ_MAYBE_UNUSED which exists in Attributes.h (because it is an attribute, not an assertion.) Undo that wrong thing: restore MOZ_STATIC_ASSERT_UNUSED_ATTRIBUTE to the correct place, have toolkit use the correct macro, and remove MOZ_UNUSED_ATTRIBUTE. MozReview-Commit-ID: 5BWWsXgbm9i
