Build: require OpenJPEG 2.x minimum, remove bundled version.

* WITH_SYSTEM_OPENJPEG is removed and is now always on, this was already
the case for macOS and Windows.
* This should not break existing Linx builds. If there is no new enough
OpenJPEG installed, CMake will no find libopenjp2 and WITH_IMAGE_OPENJPEG
will be disabled.
* install_deps.sh was updated with new package names, since distributions
put this version in a new package.

Build: update for new macOS libraries.

Run "make update", or "svn update" in lib/darwin to get the matching
precompiled libraries.

Build Environment: updates for macOS.

Mainly this is following Linux to build own xml2/lzma/ssl/sqlite and linking
them all statically. This ensures the Python ssl module uses a recent openssl
version rather than a very old one shipped with macOS.

Cleanup: use UI_ prefix for block flag

Correct own error in recent transform orientation changes

Merge branch 'master' into blender2.8

Cleanup: replace magic number
