Add the target 'build_all_generated'

This new target is used to build all generated files and only that.
This can be used to prepare everything that requires things like perl
for a system that lacks perl and then move everything to that system
and do the rest of the build there.

   *) In the UI interface, make it possible to duplicate the user data.  This
      can be used by engines that need to retain the data for a longer time
      than just the call where this user data is passed.
