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. p4raw-id: //depot/perl@10676
