Description:
------------
Question: is there consensus that PDO should use stricter parameter checking. By that I mean primarily that PDO functions follow the "modern" style of bailing out if you pass a non-scalar value parameter which expect a scalar?

[1] Like this:

 $tmp = array()
 PDO->setAttribute(PDO::ATTR_ERRMODE, $tmp)


If everybody agrees, Andrey or Johannes can fix this and similar minor flaws as we continue with the PDO_MYSQLND development. I guess there's a good number of similar flaws.

[2] Related, what about this one:

  $tmp = new stdClass()
  PDO->setAttribute(PDO::ATTR_ERRMODE, $tmp)

Reproduce code:
---------------
[1] nixnutz@ulflinux:~/php53> sapi/cli/php -r '$pdo=new PDO("sqlite:/tmp/foo.db"); $tmp = array(); var_dump($pdo->setAttribute(PDO::ATTR_ERRMODE, $tmp));'
bool(true)

[2] nixnutz@ulflinux:~/php53> sapi/cli/php -r '$pdo=new PDO("sqlite:/tmp/foo.db"); $tmp = new stdClass(); var_dump($pdo->setAttribute(PDO::ATTR_ERRMODE, $tmp));'
bool(true)
(may print a notice about the implicit casting)

Expected result:
----------------
Warning or similar + bool(false)
