* mysqli_get_server_info() cannot return null. The underlying API
is infallible.
* mysqli_select_db() func info is redundant.
* mb_detect_order() can only return array|true, not array|false.
Also make the func_info.phpt test that is supposed to catch these
kinds of issues actually work.
Make sure they're actually the same up to cases where func info
allows more accurate expressions. There are some awkward edge cases
around true/false/null limitations in union types.
Bug that regularly sneaks in: ZEND_ACC_FINAL is set before calling
zend_register_internal_class() and promptly gets ignored. Remove
this footgun by preserving flags from the original CE.
Also changing the function signatures to accept variadic args
for the fetch params. If we're already breaking Doctrine anyway,
we may as well do it properly.
We must not mix multibyte and wide character strings in the
`COAUTHIDENTITY` structure. Using wide character strings throughout
would have the advantage that the remote connection can be established
regardless of the code page of the server, but that would more likely
break BC, so we just drop the wide character string conversion of the
username.
