Remove support for non-threaded VNC server
QEMU now has a fundamental requirement for pthreads, so thereis no compelling reason to retain support for the non-threadedVNC server. Remove the --{enable,disable}-vnc-thread configurearguments, and all CONFIG_VNC_THREAD conditionals...
vnc: don't mess up with iohandlers in the vnc thread
The threaded VNC servers messed up with QEMU fd handlers withoutany kind of locking, and that can cause some nasty race conditions.
Using qemu_mutex_lock_iothread() won't work because vnc_dpy_cpy(),which will wait for the current job queue to finish, can be called with...
vnc: implement shared flag handling.
VNC clients send a shared flag in the client init message. Up to nowqemu completely ignores this. This patch implements shared flaghandling. It comes with three policies: By default qemu behaves as onewould expect: Asking for a exclusive access grants exclusive access to...
Store VNC auth scheme per-client as well as per-server
A future patch will introduce a situation where differentclients may have different authentication schemes set.When a new client arrives, copy the 'auth' and 'subauth'fields from VncDisplay into the client's VncState, and...
vnc: Fix stack corruption and other bitmap related bugs
Commit bc2429b9174ac2d3c56b7fd35884b0d89ec7fb02 introduceda severe bug (stack corruption).
bitmap_clear was called with a wrong argumentwhich caused out-of-bound writes to the local variable width_mask....
vnc: use the new generic bitmap functions
Switch to bitmap.h and bitops.h instead of redefining our own bitmaphelpers.

vnc: add a non-adaptive option
This option allow to disable adaptive behaviors in some encodings.
vnc: add a way to get the update frequency for a given region
This patch compute the update frequency (in Hz) for each 64x64 rects.Any adaptive encoding can get this value using vnc_update_freq(), andswitch to a lossy encoding if the value is too high....
vnc: refresh lossy rect after a given timeout
If an adaptive encoding has choosen to send a lossy updatebased on the result of vnc_update_freq(), then it should advertiseit with vnc_sent_lossy_rect(). This will allow to automatically refreshthis rect once it's static again....
vnc: Add ZRLE and ZYWRLE encodings.
Add ZRLE [1] and ZYWRLE [2] encodings. The code is inspire^W stolenfrom libvncserver (again), but have been rewriten to match QEMU codingstyle.

vnc: support password expire
This patch adds support for expiring passwords to vnc. It adds a newvnc_display_pw_expire() function which specifies the time when thepassword will expire.

vnc: tight add PNG encoding
Introduce a new encoding: VNC_ENCODING_TIGHT_PNG [1] (-269) with a newtight filter VNC_TIGHT_PNG (0x0A). When the client tells it supports the Tight PNGencoding, the server will use tight, but will always send encoding pixels using...
vnc: encapsulate encoding members
This will allow to implement the threaded VNC server in amore cleaner way.
vnc: threaded VNC server
Implement a threaded VNC server using the producer-consumer model.The main thread will push encoding jobs (a list a rectangles to update)in a queue, and the VNC worker thread will consume that queue and sendframebuffer updates to the output buffer....
ui: move all ui components in ui/
Move sdl, vnc, curses and cocoa UI into ui/ to cleanupthe root directory. Also remove some unnecessary explicittargets from Makefile.
