some changes were made to qxmlstream_p.h and script files directly;
however, those files are generated automatically by
src/corelib/xml/make-parser.sh and src/script/parser/make-parser.sh,
respectively, so the generator would overwrite the manual changes to the
files the next time it is run. This patch integrates those changes into
the generator rather than into the files directly.
