Enable by default the QXL paravirtualized graphic card if SPICE is
enabled. The QXL driver is VESA compatible, so it degrades gracefully if
the guest OS does not have QXL drivers.

This is mainly a wrapper to overcome the limitation of commonprefix
which makes a string by string comparisation and reports the common
prefix in both strings. However this is bad for directory handling.

IsBelowDir works around this limitation and should be used in favour of
commonprefix.

Running pylint 0.24.0 revealed 2 errors and 1 warning. Here is how I
fixed them:

* jqueue.py: silenced E1101
* netutils.py: rewrote the list comprehension using extend()
* watcher/__init__.py: fixed a missing format string parameter

These changes are backwards-compatible with pylint 0.21.1.

In version 0.21, pylint unified all the disable-* (and enable-*)
directives to disable (resp. enable). This leads to a lot of
DeprecationWarning being emitted even if one uses the recommended
version of pylint (0.21.1, as stated in devnotes.rst).

This commit changes all the disable-msg directives to disable.
