WARN_* constants are user visible, so keep existing WARN_PHP4_* for

backward compatibility, but add preferred forms WARN_PHP_* and use
these ourselves.

Rename Lib/php4 to Lib/php, Source/Modules/php4.cxx to Source/Modules/php.cxx.
 
Add typemaps for const reference so Examples/test-suite/apply_signed_char.i
works.
