Allow check for containers support to be done without CLONE_NEWNET, and then
determine support on the fly by checking for iproute2 support and a
successful clone(CLONE_NEWNET).  This lets us set a flag for later, as well
as not completely disable LXC support on a system without NETNS support.

	* src/lxc_driver.c: Make console element is output only.  Always open new
	PTY when starting a container.
	Fix string overrun when storing console name in VM def struct

    register a handler
	* src/driver.h: add sighandler function to state driver table
	* src/internal.h: define virStateSigDispatcher functions

	* src/lxc_driver.c: add sig handler function, cleanup vm when sigchld
    received from container process

	* src/remote_internal.c: NULL for sig handler (no handler) in state driver
	* src/storage_driver.c: NULL for sig handler (no handler) in state driver

  src/lxc_container.h src/lxc_driver.c: Applied second set of
  linux container patches from Dave Leskovec adding start/stop
  of domains
Daniel

* src/hash.c src/internal.h src/virterror.c: remove dandling
  domain/net/conn pointers from error data when released.
* src/lxc_driver.c: fix a NULL/0 return error mismatch
Daniel

* src/lxc_conf.c src/lxc_conf.h: cleanup patch for the conf driver
  of linux countainers, reuse XPath helpers, make string fields dynamic
  and remove a memory leak.
* src/lxc_driver.c: avoid some problems when the config directory is
  not accessible and for regression tests
Daniel

* src/lxc_conf.c src/lxc_conf.h src/lxc_driver.c src/remote_internal.c:
  applied patch from Dan Berrange to change the way the lxc driver
  works, migrating the support in the daemon, it also removes some
  compilation issues and teh way the configuration files are named.
Daniel

* configure.in include/libvirt/virterror.h src/Makefile.am
  src/driver.h src/lxc_conf.[ch] src/lxc_driver.[ch] src/virterror.c:
  Applied 3 patches from Dave Leskovec for intial support of
  Linux containers, configured off by default, work in progress.
* src/libvirt.c: improve virDomainCreateLinux xmlDesc description
