* Adds CompressInterfaceLZ4 which uses LZ4 API for compress/uncompress. * Adds CMake machinery to search LZ4 on running host. * All methods which use static data and do not modify any internal data - become `static`, so we can use them without creation of the specific object. This is possible, because the header specification has not been modified. We still use 2 sections in header, first one with file meta data, the second one with pointers for compressed chunks. * Methods `compress`, `uncompress`, `maxCompressedSize`, `getUncompressedSize` - become pure virtual, so we can override them for the other compression algos. * Adds method `getChunkMagicNumber`, so we can verify chunk magic number for each compression algo. * Renames "s/IDBCompressInterface/CompressInterface/g" according to requirement.
