  defining or creating domains

55bc5090b9 Implement schedular tunables API using cgroups 
* src/qemu_driver.c:  Add driver methods qemuGetSchedulerType,
  qemuGetSchedulerParameters, qemuSetSchedulerParameters
* src/lxc_driver.c: Fix to use unsigned long long consistently
  for schedular parameters
* src/cgroup.h, src/cgroup.c: Fix cpu_shares to take unsigned
  long long
* src/util.c, src/util.h, src/libvirt_private.syms: Add a
  virStrToDouble helper
* src/virsh.c: Fix handling of --set arg to schedinfo command
  to honour the designated data type of each schedular tunable
  as declared by the driver

946c489c68 Refactor cgroups to allow a group per driver to be managed directly 
Allow the driver level cgroup to be managed explicitly by the
hypervisor drivers, in order to detect whether to enable or
disable cgroup support for domains. Provides better error
reporting of failures. Also allow for creation of cgroups for
unprivileged drivers if controller is accessible by the user.

* src/cgroup.c, src/cgroup.h: Add an API to obtain a driver cgroup
* src/lxc_conf.h, src/lxc_controller.c, src/lxc_driver.c:
  Obtain a driver cgroup at startup and use that instead of
  re-creating everytime.
* src/util.c, src/util.h, src/libvirt_private.syms: Add a
  virGetUserName() helper

9b5655a89e Add domain events support to LXC driver 
* src/lxc_conf.h: Add queue for dispatch of domain events

53603043c7 Set default emulator in domain_conf.*, rather than the driver. 
Rather than numerous instances of:

emulator = vm->def->emulator;
if (!emulator)
    emulator = virDomainDefDefaultEmulator(conn, vm->def, driver->caps);
if (!emulator)
    return -1;

Set this value at XML parse time in the domain config, so we can depend on
it for all future emulator accesses. There were unchecked accesses in the
qemu driver that were tripping up on this if no emulator was specified in
the XML, see:

Chris Lalancette
4d3d0039e5 Convert all drivers to use old-style struct initializers; this makes a handy 
built-in TODO list for each driver.  Also rip out the internal getURI method;
it is never used by any of the drivers, and was buggy to boot.

fd52c6ff67 avoid many format string warnings 
Building with --disable-nls exposed many new warnings like these:
virsh.c:4952: warning: format not a string literal and no format ...
util.c:163: warning: format not a string literal and no format arguments
All but one of the following changes add a "%s" argument before
the offending _(...) argument.

This was the only manual change:
* src/lxc_driver.c (lxcVersion): Use %s and strerror(errno)
rather than %m, to avoid a warning from gcc -Wformat-security.

Add "%s" before each warned about format-string-with-no-%-directive:
