Create hidden API lists

Browse Source 
Android is beginning to put restrictions on the usage of private APIs.
In order to facilitate a transitionary period, some APIs will remain
accessible but issue a warning (greylist), other will see restrictions
right away (blacklist).

This patch create two new text files which will be used to store manual
lists of dex signatures of hidden APIs. These are the blacklist and
dark greylist. They should be mutually exclusive and both be subsets of
INTERNAL_PLATFORM_PRIVATE_DEX_API_FILE. The last list, light greylist,
is generated as INTERNAL_PLATFORM_PRIVATE_DEX_API_FILE minus the two
manual lists.
