* src/qemu_driver.c:  Add driver methods qemuGetSchedulerType,
  qemuGetSchedulerParameters, qemuSetSchedulerParameters

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

* configure.in: Add --with-qemu-user and --with-qemu-group args
* libvirt.spec.in: use 'qemu' for user/group for Fedora >= 12
* qemud/libvirtd_qemu.arg, qemud/test_libvirtd_qemu.aug,

virEnumFromString doesn't check for a NULL string, and will segfault if
passed one. Lots of calling code protects against this, but at least
/pool/@type parsing does not.

virExec will write out the pid of the daemonized process only. Use this
in the QEMU driver, rather than QEMU's pidfile, so we can catch errors we
might miss if the emulator bails early.

Wraps __virExec with the VIR_EXEC_DAEMON flag. Waits on the intermediate
process to ensure we don't end up with any zombies, and differentiates between
original process errors and intermediate process errors.

This way the caller can catch more errors (e.g. from a hook callback) from
the intermediate process.

sysfs files.
