- added session-unregister patch to avoid httpd SEGVs with msession module

- added session-unregister patch to avoid httpd SEGVs with msession module
  (it's something strange - in Ra, on startup apache initializes modules,
   then shutdowns them and initializes again; session module wasn't prepared
   for that (didn't shutdown other session modules cleanly). I couldn't
   reproduce such problems on newer software, but still with apache 1.3.27)

Changed files:
    php-session-unregister.patch -> 1.1
    php.spec -> 1.234
