Merges the compressor creation between RyDE and Ghostryde. Note that GhostRyde will now compress with ZIP rather than the previous ZLIB. This is backwards compatible because the decompression algorithm works with either, so files created by the old version (with ZLIB) can still be opened by the new version, and vice-versa. The new file - RydeCompression.java - is a merge of the removed functions in Ghostryde.java and the RydePgpCompressionOutputStream.java. This is one of a series of CLs - each merging a single "part" of the encoding. ------------- Created by MOE: https://github.com/google/moe MOE_MIGRATED_REVID=205102150
