[Libvir] [PATCH]0/3 OpenVZ driver : Some clean ups

[Shuveb Hussain]

Hi,

Here are some cleanups as per discussions on the list:

Change log:
* Make sure we are running on OpenVZ enebled kernel in the driver open()
method
* Some minor macro cleanups
* Use generic UUID parsing rather than own and scanf()
* Made private functions static
* New files utils.[c,h] added that have 2 functions virExec and
virExecNonBlock
* Removed popen and used virExec in openvz_driver.c
* qemu_driver.c updated to use new virExecNonBlock() functions instead
of qemudExec, which is removed

Thanks,
