Re: generating bootstrap entries for array types

The following review has been posted through the commitfest application:
make installcheck-world:  tested, passed
Implements feature:       tested, passed
Spec compliant:           not tested
Documentation:            tested, passed

The v2 patch is IMO ready to commit.

The documentation in the form of source comments is updated,
and having Catalog::ParseData() do the expansion instead of
genbki.pl is more in line with what bki.sgml says: 

      If you want to add a new method of making the data representation
      smaller, you must implement it
      in <filename>reformat_dat_file.pl</filename> and also
      teach <function>Catalog::ParseData()</function> how to expand the
      data back into the full representation.
