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

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

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 PDO_FETCH_NAMED; closes PECL #4641 by providing a way to access columns

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.

- Add +ifdefs to still allow PHP 5.0 builds of PDO

"Fix" PECL #4411
SPL is not initialized before PDO, so inheriting from SPL's runtime exception class gives PDO a broken exception class.
We don't currently have a way to express this kind of "soft" dependency in the build system, so I'm disabling inheriting from the runtime exception for now.

fix segfault & buffer overrun when there is no PDO drivers plugged in
(patch by su1d@phpclub.net)

- Add function pdo_drivers()

- the driver's key name is not zero terminated, hence we need to either
estrNcpy() it or use the driver struct.
- table headers do not support single column mode so change to two cols

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.
