I don't know how Mozilla was able to build this without defining
ST_NO_EXCEPTION_HANDLING, but looks like we have to do it so that
the compiler doesn't complain about -fno-exceptions
I separated out the AVC and AAC support code into a patch file so that
the upstream code can be updated freely without having to re-add AVC
and AAC support again. At least if the upstream changes are not too
extensive...
This should effectively backport Mozilla bug 1539686, which allows the
browser to parse the color information from WebM videos that uses HDR.
Thankfully I already redundantly edited this file myself before to
account for updates in the source, and backed this up to another
location just in case the shell script breaks my build files,
which it did!
This conditional was incorrectly changed when removing Android support.
This potentially causes issues on Linux systems by not using pthreads correctly,
which may lead to high idle CPU usage.
I've also added some notes in the update.sh script that should've been
documented, as well as changed README to README.md which Mozilla
somehow forgot to do when they updated to 1.3.3...

In order to generate these files, refer to
https://wiki.mozilla.org/I18n:Updating_Unicode_version
For those too lazy to go to the link (or if the link no longer works), we need the
following files from http://www.unicode.org/Public/9.0.0/ucd/:
- UnicodeData.txt
- Scripts.txt
- EastAsianWidth.txt
- BidiMirroring.txt
- HangulSyllableType.txt
- SpecialCasing.txt
- ReadMe.txt (to record version/date of the UCD)
- Unihan_Variants.txt (from Unihan.zip)
As well as Identifier*.txt from http://www.unicode.org/Public/security/9.0.0/,
which should be put in a "security" subdirectory under the UCD folder, and
http://www.unicode.org/Public/vertical/revision-15/VerticalOrientation-15.txt put
in a "vertical" subdirectory.
I suggest downloading all files with GetEmAll, just in case.
Change the perl command a bit, as the guide seems to be outdated:
perl ../tools/genUnicodePropertyData.pl /path/to/platform/gfx/harfbuzz/src/ /path/to/platform/intl/icu/source/common/unicode/ /path/to/UCD-directory/
Backported from Mozilla bug 1472602.
Didn't include the change in StickyScrollContainer.cpp because it breaks
linking to libxul.so in the end. It's not important anyway.
