Previously we emitted a separate one for every wrapped function,
but typically many functions have the same number of parameters
and combinations of parameters passed by reference or not.
This change significantly reduces both the size of the generated
wrapper, and of the compiled PHP extension module (e.g. by ~6% for
the stripped extension module for Xapian's PHP7 bindings).
PHP5's C extension API has changed substantially so you need to use
-php7 to specify you want PHP7 compatible wrappers.
Fixes https://github.com/swig/swig/issues/571
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.
