$row->copy doesn't work with Sybase and datetime fields

[perlpunk]

With the default datetime_setup, the date format delivered by Sybase
is not accepted for inserts.

Changing the format to ISO on connect (see comments in code), then the datetime parser
DBIx::Class::Storage::DBI::Sybase::ASE::DateTime::Format complains and
can simply be replaced by DateTime::Format::Sybase, which raises the question,
why we need the ASE datetime parser at all.

Ok, given the clusterfuck the best solution I could come up with is this workaround. I made it into a test so it is exercised going forward. Refer to the commit message for the gory details (though you already know most of them).

I do not have a more general solution in mind, short of "just make a new set of inflators/datetime_setup routines for the affected storages".

This is more or less the limit of what the current misdesigned system can do :/
