Migrating to new directory structure adopted from the RealVNC's source tree. Windows part should be complete. For the Unix part, more changes will follow.

- Compresses the source buffer into the destination buffer. The level
- parameter has the same meaning as in deflateInit. sourceLen is the byte
- length of the source buffer. Upon entry, destLen is the total size of the
- destination buffer, which must be at least 0.1% larger than sourceLen plus
- 12 bytes. Upon exit, destLen is the actual size of the compressed buffer.
-
- compress2 returns Z_OK if success, Z_MEM_ERROR if there was not enough
- memory, Z_BUF_ERROR if there was not enough room in the output buffer,
- Z_STREAM_ERROR if the level parameter is invalid.
