Richard Levitte 486f149131 util/dofile.pl, util/perl/OpenSSL/Template.pm: move parts of dofile.pl
We make a module OpenSSL::Template from the central parts of
util/dofile.pl, and also reduce the amount of ugly code with more
proper use of Text::Template.  OpenSSL::Template is a simply subclass
of Text::Template.
