[PATCH 21/43] util: xml: Disallow aliasing of negative numbers in virXPathUInt

[Peter Krempa]

Passing negative number as an alias for the max value is an anti-feature
we unfortunately allowed in virsh, but luckily never encouraged in the
XML.

Refuse numbers with negative sign when parsing unsigned int from
XPaths.
