ca36b7bc13 Added zend_internal_function.reserved[] fields, to allow extensions keep additional associated information. 
We didn't have zend_internal_function.reserved[] in PHP5, but we always allocated space for zend_function union, and extensions were able to reuse zend_function.op_array.reserved[] even for internal function. Now this is not possible. And extensions have to use zend_function.op_array.reserved[] for user functions and zend_function.internal_function.reserved[] for internal.

122d759618 Always throw TypeException on throwing zpp failures 
Introduces a ZEND_PARSE_PARAMS_THROW flag for zpp, which forces to
report FAILURE errors using a TypeException instead of a Warning,
like it would happen in strict mode.

Adds a zend_parse_parameters_throw() convenience function, which
invokes zpp with this flag.

Converts all cases I could identify, where we currently have
throwing zpp usage in constructors and replaces them with this API.
Error handling is still replaced to EH_THROW in some cases to handle
other, domain-specific errors in constructors.

927d53fda4 Change "Cannot redeclare class X" into "Cannot redeclare class/interface/trait X", meaning that the following: 
C:\> php -r "trait A { } trait A { }"

Will now properly print "Cannot redeclare trait A" instead of "Cannot redeclare class A" to make error messages a tiny bit clearer. Admittedly, a better solution can most likely be made by actually telling what the colliding object is a type of.

Internally this adds a new function:
 zend_get_object_type()
