New license, better errors, and support empty files on 3.26.0

• this release is available under the MIT license
• include filenames in parse exceptions
• handle empty files in HHVM 3.26.0

Support additional typechecker restrictions

This release supports:

• enable_experimental_tc_features=no_fallback_in_namespaces (nightlies, expected in 3.25)

Remove support for definition-finder, automatically create skeleton configuration files
