* 'phpng' of git.php.net:php-src: (53 commits)
  Use defined macro
  Refactored tidy (all tests passes)
  Reverted wrong commit Xinchen, stop commit changed configs :) You may use environment variables to ovverride default settings
  Fixed reference counting, IS_REFERENCE and IS_INDIRECT support
  Terminate string Useproper hash function
  C89 compat
  Fixed curl_close() behavior
  In most user extensions functions like mysql_close() should use zend_list_close() instead of zend_list_delete(). This closes the actual connection and frees extension specific data structures, but doesn't free zend_reference structure that might be referenced from zval(s). This also doesn't decrement the resource reference counter.
  Fixed access to uninitialized data and attempt to double free
  Fixed safe resource close. It must not de deleted (just closed), because it still may be referenced from zval(s). This fixes few ext/ftp test memory failures detected with valgrind.
  Nested PCRE calls may clobber extra->mark and it has to be reinitailized This fixes invalid memory writes (detected with valgrind) in Zend/tests/closure_047.phpt and Zend/tests/closure_048.phpt.
