Detects common public API mistakes, making it easy to quickly scan
across all changes in a new API level.
Builds in-memory representation of the current API, then runs various
detectors over the classes. It collects failures, and can ignore
known failures from a previous API level.
Example usage:
$ python frameworks/base/tools/apilint/apilint.py \
frameworks/base/api/current.txt \
prebuilts/sdk/api/21.txt
