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,
src/qemu.conf: Add 'user' and 'group' args for configuration
* src/Makefile.am: Create %localstatedir/cache/libvirt/qemu
* src/qemu_conf.c, src/qemu_conf.h: Load user/group from config
* src/qemu_driver.c: Change user ID/group ID when launching QEMU
guests. Change user/group ownership on disks/usb/pci devs.
Put memory dumps in %localstatedir/cache/libvirt/qemu
* src/util.c, src/util.h: Add convenient APIs for converting
username/groupname to user ID / group ID
* src/Makefile.am src/libvirt.c src/libvirt_private.syms src/logging.c
src/logging.h src/util.c src/libvirt_debug.syms: big cleanup of
the debug configuration option and code by Amy Griffis

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.
* configure.in src/libvirt_private.syms src/storage_backend_fs.c
src/util.c src/util.h: find and use kvm-img, qemu-img or qcow-create
dynamically at runtime, patch by Doug Goldstein
* AUTHORS: add Doug Goldstein

* qemud/qemud.c src/console.c src/network_driver.c
src/node_device_conf.c src/node_device_hal.c src/storage_conf.c
src/util.c: cleanup of some direct stderr logging

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.
* src/libvirt_private.syms src/storage_backend_fs.c src/util.c
src/util.h: use posix_fallocate() on supported systems to
allocate diskspace faster, patches by Amit Shah

* src/qemu_driver.c: Use virSetCloseExec and virSetNonBlock,
rather than qemuSet* functions. Suggested by Daniel P. Berrange.
* src/util.c (virSetCloseExec): Publicize.
* src/util.h (virSetCloseExec): Declare
* src/libvirt_private.syms: Add virSetCloseExec.
src/uml_driver.c src/util.c src/util.h src/xen_unified.c:
unify hostname lookup using virGetHostname convenience function,
