PDO driver constructors are throwing PdoException without setting
errorInfo, so create a new reusable function that throws exceptions
for PDO and will also set the errorInfo. Use this function in
pdo_mysql, pdo_sqlite, and pdo_pgsql.
Different manufacturer models may come with a
different endianness (motorola/intel) format. In
order to avoid a big refactor and a gigantic lookup
table, this commit simply attempts to switch the
endianness and proceed when values are acceptable.
Closes GH-5849.
Whether the type library is cached is actually irrelevant here; what
matters is that the symbols are imported, and since these are not
cached, we have to import them for every request. And we cannot cache
the symbols, because the import depends on the current codepage, but
the codepage is a `PHP_INI_ALL` setting.
We must not call `zend_list_delete()` in resource closer functions
exposed to userland, because decreasing the refcount there leads to
use-after-free scenarios. In this case, commit 4a42fbb worked for
typical use-cases where `xml_parser_free()` has been called exactly
once for the resource, because there is an internal zval (`->index`)
referencing the same resource which already increased the refcount by
one. However, when `xml_parser_free()` is called multiple times on the
same XML parser resource, the resource would be freed prematurely.
Instead we forcefully close the resource in `xml_parser_free()`. We
also could decrease the refcount of the resource there, but that would
require to call `xml_parser_free()` which is somewhat uncommon, and
would be particularly bad wrt. PHP 8 where that function is a NOP, and
as such doesn't have to be called. So we do no longer increase the
refcount of the resource when copying it to the internal zval, and let
the usualy refcounting semantics take care of the resource destruction.

These systems has two versions of the iovec interface dependent on
compiler flags passed, the legacy version causing little build issue.
Closes GH-5939.
Instead of storing the mapping base address and the address of
`execute_ex()` in a separate file in the temporary folder, we store
them right at the beginning of the memory mapping.
The file extension to mime type mapping *must* not depend on the file
extension's case for case-insensitive file systems, and *should* not
for case-sensitive file systems.
It does not make sense to make assumptions about `PHP_CONFIG_FILE_PATH`
during build time, since that value is never used during run time on
Windows. Since there is no `--with-config-file-path` on Windows
either, we define `PHP_CONFIG_FILE_PATH` as `""`.
This test fails occasionally due to timing issues, because the session
file may have been unlinked by the first `session_start()`'s GC. We
adapt the test expectation to this reality.
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.
