Supporting video bigger than 2GB

[chyj4747]

When I use this lib to cache video where size is bigger than 2GB, it can only cache 2GB data and then all threads(includes main ui thread) are stopped. So I changed 'int' to 'long' of this lib, it seems to work well(the file cached seems ok), but still, all threads are stopped.

@chyj4747 You are right. AndroidVideoCache uses type int in Source and Cache interfaces instead of long. So videos bigger than 2^31 bytes (2GB) will fail :( . We really must use long type.
