PHP 8.4 ext-dba function signatures

[kassner]

dba_* functions had their signature changed in PHP 8.4 to return a \Dba\Connection instance.

Please share phpstan.org/try with an error first.

Parameter #2 $handle of function dba_fetch expects resource, Dba\Connection|false given.

@kassner I think the right solution is to put dba_fetch\'1 key into old section in resources/functionMap_php83delta.php.

1. This signature is deprecated in PHP 8.3.
2. The problem is that PHPStan is thrown off by the extra variant. You could look for the root cause and fix it (the fact that information from phpstan/php-8-stubs is not used there), but the easy fix is to put dba_fetch\'1 key into old section in resources/functionMap_php83delta.php.

The problem here is that phpstan/php-8-stubs info is not applied to dba_fetch.
