Throw an IntegrityViolationError exception instead of just logging integrity violations. This makes sure the user notices.

Deleting a block doesn't set the version number to MAX_UINT64, but just increases it by one. This makes sure, that if (in case of a synchronization conflict) the block is reintroduced by another client, this is accepted.

When increasing the version number, don't only look at the version number in the block, but also at the last version number given to it by the current client. Ensure, the new version number is higher than both.

When a client deletes a block, it will never again accept it as a valid block.

* Prevent rollback to the "newest" version of a client when this version was superseded by a version from a different client.
* Use mutex/locks to secure access to KnownBlockVersions

* Block versions don't have to be globally nondecreasing, but only per client id. This solves potential synchronization conflicts in a multi-client setting.
* Use cpputils::Serializer and cpputils::Deserializer instead of std::ifstream for storing/loading the block version list

Implement a VersionCountingBlockStore that checks that version numbers are nondecreasing. Currently, the block store is not used yet and the state is not stored over different runs of CryFS. This comes with future commits.

Ciphertext blocks are split into subdirectories (before, all were on top level) to reduce number of files per directory. Some unix tools don't work well with directories with too many entries.

Implemented BlockStore::blockSizeFromPhysicalBlockSize. This will be used to let the user configure physical block size instead of virtual block size.
