Do not prepend ? on nullables in ReflectionType::__toString()

Better BC with 7.0.

Updated UPGRADING about function call args

Return true for is_object() on Incomplete_Class

gettype(): Use "resource (closed)" instead of "unknown type"

Remove sql.safe_mode

This is one of the last old and odd deprecated settings we still have in PHP, it was never fully implemented in all the database extensions and should probably have been gone back in 5.4, along with safe_mode. Although if my memory strikes me right, mysql was also supporting it back then, but not mysqli.

So far only interbase was supporting this feature, and the removal of it causes two effects for interbase:
- CREATE DATABASE is now allowed no matter
- The default database set by php.ini (ibase.default_db) is no longer forced

Implement #38992: invoke() and invokeArgs() static method calls should match

We don't want ReflectionMethod::invoke() to simply ignore its first argument,
if the method to invoke is a static method. Instead we match its ZPP with
that of ReflectionMethod::invokeArgs(). Furthermore, we apply the DRY
principle by factoring out the code to a common helper function to prevent
inadvertent future divergence of the implementations of both methods.

As can be seen from the necessity to adapt some test cases, this causes a
BC break for some pathological cases. Therefore we apply this patch to PHP
7.1 only, which is still in beta phase.
