Rolf Eike Beer 4be6783711 read less from version headers into variables
Instead of reading the whole file using file(READ) and later matching on the
whole file use file(STRINGS ... REGEX) to get only those lines we are
interested in at all. This will make the list much smaller (good for debugging)
and also the regular expressions will need to match on much smaller strings.

Also unset the content variables once they are not used anymore.
