XML requires escaping for certain characters, and we need to consider
this when writing out qrc files (which use XML).
This commit introduces a helper function,
_qt_internal_escape_xml_characters, to take care of the escaping.
It uses regular expressions to process the input strings. We take care
to start with '&', as '&' needs to be escaped, too.
We minimize the amount of escaping we're doing (the exact rules
differing between attributes and text), to avoid unnecessary work that
needs to be done when configuring a project. This is achieved by a
SUBSET option which can be passed to _qt_internal_escape_xml_characters.
