Fix Bug #34687; error information from query() not passed back

- Add PDO::setAttribute(PDO::ATTR_STATEMENT_CLASS)

Declare functions used by driver as PDO_API in php_pdo_driver.h

Proper handling for databases that need to pre-calculate length of large
columns, which is not normally done for performance reasons.

NULLs into empty strings as well as the other way around. It still doesn't

help a great deal in the long run, but at least the option is there.

Make sure hash tables are nulled out to avoid double freeing them.

Added:

proto bool PDOStatement::closeCursor()
Closes the cursor, leaving the statement ready for re-execution.

The purpose of the function is to free up the connection to the server so that
other queries may be issued, but leaving the statement in a state that it can
be re-executed.

This is implemented either as an optional driver specific method (allowing for
maximum efficiency), or as the generic PDO fallback if no driver specific
function is installed.

The PDO generic fallback is semantically the same as writing the following code
in your PHP script:

do {
while ($stmt->fetch())
;
if (!$stmt->nextRowset())
break;
} while (true);

add a bit of a hack to cater for pgsql prepared statements.

These are effectively named statements with strong constraints on the naming
format. We cater for this in a fairly generic way: allow a driver to replace
the format string we use to generate names from positional parameters. In
addition, if that format is set, we always force a rewrite from regular names
to the strongly enforced names.

Add a PDO_ATTR_STRINGIFY_FETCHES attribute, which is used to convert integer or
floating point values into strings during fetch. This is a compatibility hack
for drivers that return native types rather than string representations.

We use this flag in the test suite to persuade postgres tests to pass.

add an attribute for returning the driver name

Add PDO_FETCH_NAMED; closes PECL #4641 by providing a way to access columns
by name, even when multiple columns have the same name:

by name, even when multiple columns have the same name:

$sql = "SELECT 1 a, 2 a, 3 b, 4 c, 5 d, 6 c, 7 a";
echo "$sql\n";
print_r($db->query($sql)->fetchAll(PDO_FETCH_NAMED));

Array
(
[0] => Array
(
[a] => Array
(
[0] => 1
[1] => 2
[2] => 7
)

[b] => 3
[c] => Array
(
[0] => 4
[1] => 6
)

[d] => 5
)
)

Also added two new attributes for use at prepare time;
PDO_ATTR_FETCH_TABLE_NAMES and PDO_ATTR_FETCH_CATALOG_NAMES instruct the driver
that the names of the columns that they return to PDO should include the table
and catalog names respectively. Both attributes may be used together or
independently. The catalog, table and column name components should be
separated by a . character.

Fix a dumb bug that would effecively ignore persistent connections and create a
new one each time.

Add a hook for persistent connections: it is called when the object goes out of
scope, and offers the driver an opportunity to release per-request scoped data
at the right time.

This hook is used by pdo_sqlite to unregister UDFs, which are dangerous to keep
registered between requests.

Various compiler warning fixes.

- Reserve some bits for flags

- Add some fetch column related capailities
- Add direct (classtype based) unserializing capabilities

Alan: moved your fields away, but reserved you a pointer.

Changed PDO::lastInsertId() to have following proto:

string PDO::lastInsertId([string name])

this allows arbitrary unique identitifers to be returned from the driver.

The optional name parameter is for databases that require additional contextual
information to be able to return the correct identifier. None currently use
it, but pgsql will be on the list of drivers that do.
