dev release DBD::Oracle 1.57_00 is on its way to CPAN

[Yanick Champoux]

DBD::Oracle version 1.57_00 is on its way to CPAN. This release is
small, but should make some Win32 users happy. The changelog is pasted
below.

As usual, the dev release will be promoted to general use in two
weeks, assuming no problem is found.

Enjoy,

1.57_00 2013-02-07
[BUG FIXES]

- fix RT46628 - bind_param_inout ORA_RSET causes MSWin32 access
violation and RT82663 - Errors if a returned SYS_REFCURSOR is not
opened (Martin J. Evans)

If a procedure/function returns a SYS_REFCURSOR which was never opened
DBD::Oracle magics a DBI statement handle into existence and attempts
to describe it (which fails). This change examines a returned
SYS_REFCURSOR and if it it is initialised but not executed does not
create a DBI statement handle and returns undef instead. So now if you
have a procedure/function which returns a SYS_REFCURSOR and never open
it you'll get undef back instead of a useless statement handle.
Extended 50cursor.t test to check the above fix.
