Xpra

* fix launcher: don't block the UI whilst connecting, and use a lower timeout, fix icon lookup on *nix
* fix clipboard contents too big (was causing connection drops): try to compress them and just drop them if they are still too big
* x264 or vpx are now the default encodings (if available)
* compress rgb24 pixel data with zlib from the damage thread (rather than later in the network layer)
* better build environment detection
* experimental multi-user support (see --enable-sharing)
* better, more accurate "xpra info" statistics (per encoding, etc)
* tidy up main source directory
* simplify video encoders/decoders setup and cleanup code
* many debian build files updates
* remove 'nogil' switch (as 'nogil' is much faster)
* test all socket types with automated tests

* fix man page typo
* fix non bash login shell compatibility
* fix xpra screenshot argument parsing error handling
* fix video encoding mismatch when switching encoding
* fix ssh mode on OpenBSD

* zlib compatibility fix: use chunked decompression when supported (newer versions)

* fix xpra launcher icon lookup on *nix
* fix big clipboard packets causing disconnection: just drop them instead
* fix zlib compression in raw packet mode: ensure we always flush the buffer for each chunk
* force disconnection after irrecoverable network parsing error
* fix window refresh: do not skip all windows after a hidden one!
* Fedora 16 freshrpms spec file fix: build against rpmfusion despite more limited csc features

* fix xpra_launcher
* fix DPI issue with Xdummy: set virtual screen to 96dpi by default
* avoid looping forever doing maths on 'infinity' value
* fix incomplete cloning of attributes causing default values to be used for batch configuration
* damage data queue batch factor was being calculated but not used
* ensure we update the data we use for calculations (was always using zero value)
* ensure "send_bell" is initialized before use
* add missing path string in warning message
* fix test code compatibility with older xpra versions
* statistics shown for 'damage_packet_queue_pixels' were incorrect

* new packet encoder written in C (much faster and data is now smaller too)
* read provided /etc/xpra/xpra.conf and user's own ~/.xpra/xpra.conf
* support Xdummy out of the box on platforms with recent enough versions of Xorg (and not installed suid)
* pass dpi to server and allow clients to specify dpi on the command line
* fix xsettings endianness problems
* fix clipboard tokens sent twice on start
* new command line options and UI to disable notifications forwarding, cursors and bell
* MS Windows clients can now choose the remote clipboard they sync with ('clipboard', 'primary' or 'secondary')
* x264: adapt colourspace conversion, encoding speed and picture quality according to link and encoding/decoding performance
* automatically change video encoding: handle small region updates (ie: blinking cursor or spinner) without doing a full video frame refresh
* fairer window batching calculations, better performance over low latency links and bandwidth constrained links
* lower tcp socket connection timeout (10 seconds)
* better compression of cursor data
* log date and time with messages, better log messages (ie: "Ignoring ClientMessage..")
* send more client and server version information (python, gtk, etc)
* build cleanups: let distutils clean take care of removing all generated .c files
* code cleanups: move all win32 specific headers to win32 tree, fix vpx compilation warnings, whitespace, etc
* more reliable MS Windows build: detect missing/wrong DLLs and abort
* removed old "--no-randr" option
* drop compatibility with versions older than 0.3: we now assume the "raw_packets" feature is supported
