This change required some changes to the editions default handling code
because the descriptor.proto changed upstream [2]. The defaults are no
longer one feature set but are split into overridable and
not-overridable features which have to be merged.
I had to do bootstraping in 4 phases but the results should be correct:
1. generate everything depending on descriptor.proto
2. generate new defaults binary proto
3. adjust all code that works with defaults (*/edition.go files)
4. generate everything else
The was required because 1. is a prerequisite for 3. while 2. and 3. are
a prerequisite for 4. (2. and 3. can probably be done in parallel).
The new release also introduced new conformance tests. The go
implementation is not yet conformant and the tests will be fixed in a
follow up change because they require changes to the protojson and
protoext encoders.
