Merge "Configure ObsoleteLintCustomCheck lint as fatal"

# Treat LintError as fatal to catch invocation errors

--fatal_check LintError

# ObsoleteLintCustomCheck is a warning by default, but lint ignores the

# checks from the subject jar if this issue is raised.

# This should be an error for AOSP. If we create a check, we expect it

# to run, otherwise we want an error.

--fatal_check ObsoleteLintCustomCheck

# Checks which do not apply to the platform (implementation

# in lint assumes that it's running on app code)
