- 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...

.
- corrected a bug that caused file copy error: a closeFile() was missing when the file is complete. Because of delays in fwrite, the file would not be always co
mplete, nor exist at all for small files (e.g. cache files), which in the later case caused the copy error.
Warning: needs a make clean in libretroshare to recompile.

- suppressed old DwlQueue class
- turned mDownloads into a list of pointers to allow easy cross-info update between queue and std::map of downloads
- added queue functionality for moving files top/bottom/up/down
- added the necessary functions in rsFiles
Put back display of exact sizes in FileTransferInfoWidget
Suppressed some warnings.
**Warning**: this commit requires a make clean.

- added file priority strategy based on which files are requested first. This provides:
- equal file speed for files with equal (source,priority)
- effective priority speed for file of same source but different priority
- removed state variable load/save from turtle, as it's not needed anymore (FileRequest re-opens tunnels as needed)
- manage availability per peer instead of per file type: direct peer ids always assume file availability, while turtle tunnels don't
I still need to make the download queue work, and code this gui for it.

- 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

- implemented transfer protocol for chunk availability maps between peers (not enabled yet though)
- suppressed rsiface directory from retroshare-gui
- moved notifyqt.{h,cpp} to gui/
next moves:
- send availability maps to clients;
- connect turtle search to unfinished files;
- test multisource download with unfinished files.

The side effect is that even when stopped, downloads show the correct downloaded size (up to the size of one chunk).

- a given chunk strategy
- the availablility map of each source
- Integrated this into ftFileCreator
- added gui menu in file transfer+right click to change the chunk strategy: streaming vs. random
Next step:
- loading/saving file downloading state and availability map
- displaying chunk details in the selected transfer tab (e.g. list of currently worked chunks, and their current downloading completion)

NB: This is not yet working. so SVN is now officially broken :(
Hope to have the bugs ironed out soon.

It is now almost ready for integration with rs.
Added ftserver3test.cc which successfully tests:
* Hashing of a directory.
* Transfer of Cache Files.
* Local Searching.
* Remote Searching.
* Download from multiple sources.
