a transfer not finish if the original surce for a crc is not here anymore.
If you have a unfinished transfer do a force-check after restart to get back chunks that
where still on verificaiton stage.

- unchecked chunks are not made available to swarming sources, not saved as done.
- force check now uses the simple method to put all chunks in checking mode
- force checked files can be cancelled (finally!)
- improved display (use red for active chunks, yellow for checking)
- cache file are not using chunk checking (assume_availability=true)
The code still contains the #ifdef. It should be removed soon if everything works ok.

- tunnels can borrow data chunks from only slower tunnels, to prevent blocking fast tunnels
- tunnels can handle up to 50 data chunks at once instead of 5
Multi-source transfers are generaly faster and more stable.

Validated chunks are shared to other peers. Force check is now very simple since it just turns all chunks into "needs checking" mode
and sums are asked to sources. Sources maintain a temporary cache of chunks. Since sums are requested sparsely, this should not
affect the sources in terms of performance. We can still imagine precomputing and saving sha1 of chunks while hashing them.
For backward compatibility reasons, the following has been setup *temporarily* in this version:
- unvalidated chunks are still considered as already obtained, and are shared and saved
- force check has been disabled
- final file check is maintained
- in case of file fail, the old checking mode will be used.
All changes for next version are kept in the define 'USE_NEW_CHUNK_CHECKING_CODE' that will be made the default in a few weeks.
At start, I expect most chunk to stya yellow during download, until most sources are able to provide chunk hashs.

- corrected 2 potential flaws of swarming causing request of unavailable data (This should normally be taken care of on the server side!)
- improved swarming test code with fault simulation
- only ask CRC32 maps to peers that have a complete file.

libretroshare/src/retroshare/
All the relevant headers have been modified to reflect that change.
This allows installation of libretroshare on a system, headers will
be put in $WHEREVER/retroshare/ and we keep the ability to compile
against them, be it on the system or in the SVN tree.

- 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...

- 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).
