* ext/dba/tests/setup/setup_dba_tests.inc: sort test output
Iterating through a database with firstkey() and nextkey() is
guaranteed to retrieve all rows, but apparently not in any particular
order. This is causing a test failure for at least one user, so we
steal the sort() approach from GDBM to ensure that the output is
predictable.
* ext/dba/tests/dba_*.phpt: sort expected test output
The actual output is now sorted for consistency, so we need to update
the expected output as well. As a nice side effect, some differences
in the expected outputs for the various engines have been eliminated.
Closes GH-14786
* ext/pgsql/tests/80_bug14383.phpt: sort expected test output
This test uses a routine from ext/dba that now sorts its (actual)
output, so we have to sort the expected output here as well.
* ext/dba/tests/setup/setup_dba_tests.inc: update comment
After doing some more digging, it looks like GDBM isn't the only
engine where the iteration order with firstkey() and nextkey()
might change unexpectedly.
Generalises tests for all the different drivers.
Run the general test for the various drivers.
This allows support for parallel testing as the tests now do not rely on the same DB file.
