A clipboard owner can indicate that it can supply the data the clipboard
owns in multiple formats, so make the data passed with a
VD_AGENT_CLIPBOARD_GRAB message an array of types rather then a single
type.
-includes most of Hans' review fixes (up to the SelectionRequest comment [4]) & X11 wips sent by Hans (10x!)
-use the VD_AGENT_CLIPBOARD_* types in the platform code
-add ifs for VD_AGENT_CAP_CLIPBOARD_BY_DEMAND in both sides
-support the GRAB/REQUEST/DATA/RELEASE verbs in both ways
-pasting clipboard data is now "only-by-demand" from both sides (client and agent), whose behavior is symmetric
-client and agent don't read or send the contents of the clipboard unnecessarily (e.g. copy, internal paste, repeating paste, focus change)
-set client as clipboard listener instead of application
-add atexit(cleanup) in win platform
linux:
-instead of clipboard atom selection instead of XA_PRIMARY
-enable USE_XRANDR_1_2 and support clipboard in MultyMonScreen
-send utf8 with no null termination, remove ++size
-add xfixes in configure.ac & Makefile.am
windows:
-bonus: support image cut & paste, currently only on windows
not done yet:
-clipboards formats are still uint32_t, not mime types stores as strings
-platform_win is still used, not the root window
-not replaced the ugly windows CF_DIB in agent/winclient
* windows - untested
* linux - small strings both ways, large implemented differently:
* client to guest - support INCR
* guest to client - we supply a single possibly very large property
* requires server changes in next patch to work with spice-vmc
3 available mechanisms: by public key, by host name, and by certificate subject name.
In the former method, chain of trust verification is not performed.
The CA certificate files are looked for under <spice-config-dir>/spice_truststore.pem
windows <spice-config-dir>=%APPDATA%\spicec\
linux <spice-config-dir>=$HOME/.spicec/
-move _focused & _pointer_in_window from RedWindow to RedWindow_p's
-move shadow focus & cursor handling to sync()
-add reset_cursor_pos() to Platform
-Monitor set_mode()/restore() use virtual do_set_mode()/do_restore()
The process loop is responsible for: 1) waiting for events 2) timers 3) events queue for
actions that should be performed in the context of the thread and are pushed from other threads.
The benefits:
1) remove duplicity: till now, there was one implementaion of events loop for the channels and
another one for the main thread.
2) timers can be executed on each thread and not only on the main thread.
3) events can be pushed to each thread and not only to the main thread.
In this commit, only the main thread was modified to use the new process loop.
