Implement commands MAKE_ASSIGNABLE and REVERT_ASSIGNABLE in pcid in
the same way as they were implemented in libxl_pci.c
Replace original logic in libxl_pci.c by calling appropriate functions
from pcid.
This is quite huge patch, as lots of code were moved from lixbl_pci.

Add draft version of pcid server (based on vchan-node2), which can receive
messages from the client.
Add essential functionality to handle pcid protocol:
- define required constants
- prepare for handling remote requests
- prepare and send an error packet

Current vchan implementation, while dealing with XenStore paths,
allocates 64 bytes buffer on the stack which may not be enough for
some use-cases. Make the buffer longer to respect maximum allowed
XenStore path of XENSTORE_ABS_PATH_MAX.

vchan server creates XenStore entries to advertise its event channel and
ring, but those are not removed after the server quits.
Add additional cleanup step, so those are removed, so clients do not try
to connect to a non-existing server.

When shutting down (or rebooting) the platform, Xen will call stop_cpu()
on all the CPUs but one. The last CPU will then request the system to
shutdown/restart.
On platform using PSCI, stop_cpu() will call PSCI CPU off. Per the spec
