2edb61758b Improvements to file transfer:
- 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.

dd474cfddf added chunk splitting in case part of the file transfer data does not come. Added strategy to ask again for missing data. The combination of these two cannot result into an infinite loop (as before)

4bb4fc11e2 This intimidating patch renames libretroshare/src/rsiface/ to
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.

8bfc74485a First implementation of per-chunk CRC32 check. This is triggered
- 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...

a70b106005 - added NETWORK_WIDE flag to remote dir model download
- 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.

96147a9734 added flags to file request: RS_FILE_HINTS_ASSUME_AVAILABILITY to not wait/ask for chunk maps. Used for cache transfer and also whenever the turtle traffic is not involved, such as chat file exchange, and RS_FILE_HINTS_NETWORK_WIDE to force using turtle routing for traffic. Also moved turtle tunnel start/stop orders from ftServer to ftController

cfaaec31c7 - Implemented chunk-based file transfer from partial sources. This in particular means:
- 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

f4a2eaecce - implemented a visualisation for currently handled chunks, availability maps, and transfer info
- 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.

b6c048a5fd Implemented load/save of chunk maps for current downloads.
The side effect is that even when stopped, downloads show the correct downloaded size (up to the size of one chunk).

25a09900e9 - Added a ChunkMap class responsible for allocating new chunks to be downloaded, according to
- 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)
