Add support of reading and writing compressed clusters. Support zlib and zstd compressions. L2 cache: store entire L2 entries, not only standard cluster addresses. Read path. Offsets of compressed clusters cannot be determined, therefore replace QcowFile.file_offset_read() with QcowFile.file_read(). This method reads the cluster, decompresses it if necessary and returns the data to the caller. Write path. QcowFile.file_offset_write(): since writing to compressed clusters is not generally possible, allocate a new standard (non-compressed) cluster if compressed L2 entry is encountered; then decompress compressed cluster into new cluster; then return offset inside new cluster to the caller. Processing of standard clusters is not changed. Signed-off-by: Eugene Korenevsky <ekorenevsky@aliyun.com>
