* Intern all strings and dotted names in the DAML-LF protobuf encoding
On one of our huge DAML code bases this has brought down the size of the
DALF by 60% and cut the memory usage during decoding by 50%.
The `@QUERY-LF` tests in the damlc integration tests check that the
interning actually works.
* Add scala decoder support for interned strings
* Memoize versionisOlderThan. Speeds up decoding by 6x.
* Properly fix the performance problem with version ordering
LanguageVersion.ordering was a `def` and not `val` causing us to
recreate the ordering tables every time.
* Clean up //daml-lf/archive:decode-test
* Use int32 for interning indices
* Adapt QUERY-LF tests
* Strip a few useless field_ prefixes
* Add test for uniqueness in interning tables
* Drop field_ prefix from jq queries
* Fix Scala encoder
* Fix bond-trading tests
* Rename decode-test to decode-tester
* Address @cocreature's comments
* daml-lf: proper versioning for reading internedStrings
* daml-lf repl: revert change
