The Grand Trek: move the *.t files from t/ to lib/ and ext/.

No doubt I made some mistakes like missed some files or
misnamed some files.  The naming rules were more or less:
(1) if the module is from CPAN, follows its ways, be it
    t/*.t or test.pl.
(2) otherwise if there are multiple tests for a module
    put them in a t/
(3) otherwise if there's only one test put it in Module.t
(4) helper files go to module/ (locale, strict, warnings)
(5) use longer filenames now that we can (but e.g. the
    compat-0.6.t and the Text::Balanced test files still
    were renamed to be more civil against the 8.3 people)
installperl was updated appropriately not to install the
*.t files or the help files from under lib.

TODO: some helper files still remain under t/ that could
follow their 'masters'.  UPDATE: On second thoughts, why
should they.  They can continue to live under t/lib, and
in fact the locale/strict/warnings helpers that were moved
could be moved back.  This way the amount of non-installable
stuff under lib/ stays smaller.
