vchan/vm: implement libvchan_cleanup to release resources used by vchan link
...
In most cases after vchan close program terminates (or reexec itself to wait
for next connection), so cleanup isn't needed (not sure how about evtchn and
shared pages...).
But in case of stubdom it is needed to cleanup before waiting for new
connection - we can't reexec agent there.

vchan: fix multiple server instances from single process
...
Use new u2mfn_fd for each ring_init call - each open fd to u2mfn is capable to
do only one u2mfn_alloc_kpage, so it can't be reused at the next ring_init.

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().
