Merge branch 'master' of git.php.net:/php-src

* 'master' of git.php.net:/php-src:
  Made "result", "statement" and "last_message" to always use Zend MM heap. (even for persistent connections these entities don't relive request boundary)
  Fixed memory leaks
  Use interned strings for "magic" property of internal classes. (not copyied into SHM)
  Reverted incomplete fix and too strict asserts.
  Mark persistent connection related data as "thread-local".
  Persistent resources are "thread-local". Register persistent resources through new functions zend_register_persistent_resource()/zend_register_persistent_resource_ex().
  PCRE cache is "thread-local"
  Allow reference-counting on "thread-local" persistent zvals
