client: support clipboard/selection-owner model (v2)

-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
