Description:
------------
Apparently nobody has tested apache2filter SAPI when doing 5.6.0alpha1 release, so it doesn't build since sapi_request_info *post_data* has been removed.

Unfortunately this is beyond my PHP internals knowledge, so somebody else needs to fix this.

Expected result:
----------------
apache2filter compiled

Actual result:
--------------
/tmp/buildd/php5-5.6.0~alpha1+dfsg/sapi/apache2filter/sapi_apache2.c: In function 'php_apache_request_ctor':

  SG(request_info).post_data = ctx->post_data;
