Merge branch 'PHP-5.6'
Leftover: Bump version to 5.7.0
Remove 128.0.0.0/16 and 191.255.0.0/16 from the reserved list.

These were returned to the general allocation pool by RFC 3330, and hence
shouldn't cause an IP address validation failure due to being reserved. At
least 128.0.0.0/16 is in use on the public Internet today.

Fixes bug #66229 (128.0.0.0/16 isn't reserved any longer).

Fix php_module_startup() when loading more than one additional module

Dereferencing addition_modules within php_module_startup would
point to a vector entirely on the stack (which is of course, wrong).

Use a specialized helper to keep BC with the current php_module_startup()
calling semantics.
