<content type='text'>
A feature registry lets us to reference features by name, rather than a concrete langver.
It makes easier to find feature references and releasing incubating features (under max
langver during the development). Features are described at
`yql/essentials/data/language/features.json` and the C++ code is generated. The unit
`feature.h` also introduces a convenience functions to check a feature availability and
emit a standard error message. All features in the translator where replaced with named.
