Pre-evaluate magic constants

Partial port of class declarations

Prepare zend_ast_decl for reuse with classes

Port methods

The duplicated magic method checks are ugly

Support static closures

Handle function doc comments

Fix lexer/compiler interdependency

Use dedicated func_decl ast node

Functions need a bunch of extra info, that becomes inconvenient
to handle using the normal ast structure.

Lineno corrections

Preliminary function decl support

Problem: __FUNCTION__ etc don't work anymore, due to lexer/parser
interdependency.

approx correct linenos in errors

Store (bad) estimate of lineno with ast

Currently not used yet

Support creating of ast nodes with >3 children
