Makefile:
Revert previous build "optimization" -- we need check-for-zlib and
more importantly mk-symlinks done before we try to build, otherwise a

[PATCH] xen.vncserver-quiet-configure.patch
When configure looks for VNC Server library installation by
executing libvncserver-config, make sure we don't print messages to
the console if we cannot find the libvncserver-config program.

[PATCH] xen-libxc-static-build.patch
Fix build of the static library.
As it was depending on an undefined objects variable (OBJS), its
dependency list was null and thus it ended up empty.
Also optimize the depedency checking so we don't need a submake. Not
too great an optimization, but it makes it short :)

Implement the parts of vm save which need interaction with xend
as part of xend, instead of using xfrd.

XendDomainInfo.py:
Add suspended state and threading Condition with notification, allowing
easy waiting for state changes.
XendDomain.py:
Implement the parts of vm save which need interaction with xend
as part of xend, instead of using xfrd. Set state to "suspended"
when detecting a suspended domain.
Fix reading output from subprocesses.
Fix ValueError in xen_domain().
xc.c:
Remove python binding for xc_linux_save.
xc_linux_save.c:
Implement the parts of vm save which need interaction with xend
as part of xend, instead of using xfrd. Also run xc_linux_save

Clean up vbd probing, and include hardware sector size in the probe
information. blkback ensures that all requests are aligned to
hardware sector size and returns error if this is not so.
In blkfront we now have a request_queue per vbd, with hardsect_size
set appropriately.
It is now once again possible to mount a CDROM in a domU.
