- by the right-click+Force Check on files.
- when a global hash on a downloaded file does not match the announced hash.
When a CRC map check is ordered, the CRC map is requested to one of the sources for the current file download.
When received, all downloaded chunks are checked w.r.t the reference CRC and marked as not done if the CRCs do not match.
The exchange of CRC32 map and requests has been tested, as well as CRC map checking during download (force check).
To be implemented soon:
- caching of CRC32 maps (although these are fast to compute)
- CRC32 map packets for normal downloads. For now these work only for turtle tunnels.
- handling of errors if the CRC never comes. For now, the download will stay stuck in "Checking..." mode.
So, don't play too much with the force check feature for now...

- exchange of chunk availability maps from different peers
- correct handling of what is available to which source before asking the data
- correct display of chunks in the progress bars
- generalised the use of compressed chunk maps
- removed the size parameters from the hash search functions
- In addition:
- suppressed a number of per-value transfers of std::string
- improved the FileTransferInfo Widget, to show some additional info
Still to be done:
- chunk map exchange for non anonymous traffic (easy)
- improve accuracy of completion for uploads (for now it's a integer number of chunks)
- check compilation on windows
