Initial import from the monolithic Qt.

This is the beginning of revision history for this module. If you
want to look at revision history older than this, please refer to the
Qt Git wiki for how to use Git history grafting. At the time of
writing, this wiki is located here:

http://qt.gitorious.org/qt/pages/GitIntroductionWithQt

If you have already performed the grafting and you don't see any
history beyond this commit, try running "git log" with the "--follow"
argument.

+This tool greps through files for SIGNAL() or SLOT() macros and pipes the signals/slots
+through QMetaObject::normalizedSignature().
+
+Rationale: In connect statements, you'll get a micro-speed update when passing in normalized
+signatures for signals and slots.
+
+Run it without any arguments to see the command line parameters.
+
+Typical usage on Qt:
+
+# find all files with non-normalized signal/slot connections and p4 edit them
+normalize $QTDIR/src | xargs p4 edit
+# replace all non-normalized signal/slots
+normalize --modify $QTDIR/src
+# p4 diff to see that everything is OK then submit :)
+p4 submit $QTDIR/src/...
