Fixed bug #35694 (Improved error message for invalid fetch mode).

MFH: fix #35508 (PDO fails when unknown fetch mode specified)

Fix #35431; LAZY fetch and fetchAll == crash.
Lazy makes no sense with fetchAll; disallow it.

MFH: fix #35430 (PDO crashes on incorrect FETCH_FUNC use)

Doh, need to canonicalize parameter names (by prefixing with :) before
attempting to remap them to positional args.

Bug: when stringify fetch mode is on, and the driver returns a string instead
of a stream for a LOB parameter, PDO would incorrectly return NULL for that
column.

Fix for #35332.
The problem is caused by the user mixing positional and named parameters.
PDO was blindly adding the parameters, unaware that the same parameters were
already allocated by

What we do now is register the parameter with the driver before adding it to
any hash. This gives the driver an opportunity to normalize the name and
parameter number. PDO can then ensure that only one entry is occupied in the
hash for a given parameter.

Closes PECL #5809; PDOStatement::execute(array(...)) would modify its args.
It should behave like bindValue() not bindParam().

When populating bound columns, override the returned type with the type
specified by the user in their bind.

remove traversable interface; apparently it's not enough, and this stuff is too
magical to figure out wtf should be added.

closes PECL #5027; PDO_FETCH_NAMED not handled via setFetchMode().

add __sleep and __wakeup functions to prevent serialize/deserialize from being used on PDO objects. Refs PECL #5217
