[SERVER] Refactor uplink/cache handling, improve crc checking
The cacheFd is now moved to the uplink data structure and will
only be handled by the uplink thread.
The integrity checker now supports checking all blocks of an
image. This will be triggered automatically whenever a check for
a single block failed.
Also, if a crc check on startup fails, the image won't be discarded
anymore, but rather a full check will be initiated.
Furthermore, when calling image_updateCacheMap() on an image that
was previously complete, the cache map will now be re-initialized,
and a new uplink connection created.
