win/vchan: remove outstanding evtchn events on libvchan_wait
...
Windows evtchn driver can double fire on one event (details in
xenpci/evtchn_device_interface.c:EvtChn_EvtIoWrite). Less intrusive way of
fixing it is just remove all events from queue on libvchan_wait (to prevent
queue fill).
This won't hurt because we are interested in events only sent
after xc_evtchn_unmask call which is one line below.

Revert "win: unmask evtchn before checking if libvchan_wait is needed"
...
This reverts commit f7ce10db8f76f752cf9d65b420de352e70bdb048.
This should be fixed by doing 0-length reads in qrexec main loop (instead of
real read of fired port number).

win: unmask evtchn before checking if libvchan_wait is needed
...
This should prevent the race, when evtchn is signalled between condition check
and libvchan_wait call.

vchan: introduce features macros
...
Use features macros (QREXEC_RING_V2 and ASYNC_INIT) instead of directly
depending on building environment. The macros are turned on (when required) in
libvchan.h based on target system.

libvchan_server_init() now does not wait for a client to connect. A server should wait for an incoming event and then call libvchan_server_handle_connected().
