Improves readability, particularly wrt the pending CreateFromXML changes.
This will also help implementing File->Block volume creation in the future,
since some of this code will need to be moved to a backend agnostic file.

vol-clone is a convenience function, requiring only a volume to clone and a
new name.

vol-create-from is a direct mapping to the public API, which allows cloning
across pools, converting between formats, etc, but requires an xml file to be
passed

Also checkin regenerated docs due to API change.

* src/lxc_container.c: drop LXC CAP_SYS_BOOT capability to avoid
  reboot from inside containers, patch by Ryota Ozaki

By checking the pid every retry period, we can quickly determine if
the process crashed at startup, rather than make the user wait for
the entire timeout (3 seconds).

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.

This ensures the user will actually see 'hook' function error output.

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.
