bitkeeper revision 1.1527.2.1 (429368a2F0SR4yrzuHsrRucuwriYqA)

Implement the parts of vm save which need interaction with xend
as part of xend, instead of using xfrd.
Execute xc_linux_save in a seperate process so that it can't
crash xend.  Also handle errors passed from xc_linux_save.
xen_domain.c:
  Disable save in xfrd.
xc_save.c:
  new file
Makefile:
  Add xc_save.
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
  in a seperate process.
xc_linux_restore.c:
  Flush output so that xend picks it up timely.
  Also disable debug output again.
xc.h:
  Update xc_linux_save prototype and fix comments for xc_linux_{save,restore}.
ignore:
  Add tools/xcutils/xc_save.
