Fix parser stack destruction with dummy ENCAPSED_AND_WHITESPACE

T_ENCAPSED_AND_WHITESPACE is now specified to always hold a value,
so give it a NULL value in the dummy cases.

Use efree_size() instead of efree() where posible

Handle remaining magic constants in parser as well

As far as I can see the !filename case cannot occur, so I dropped
it.

eval() with parse error uses clean shutdown now

Remove ZEND_ACC_INTERACTIVE and CG(interactive)

As far as I can discern these are leftovers of the interactive
shell implementation that was used before PHP 5.4. Now the readline
ext

Remove ZEND_ACC_INTERACTIVE and CG(interactive)

As far as I can discern these are leftovers of the interactive
shell implementation that was used before PHP 5.4. Now the readline
ext makes use of normal eval calls for this.

So, dropping these until there is evidence to the contrary, as they
currently wouldn't work anyway.

further fixes on core

first shot on merging the core fro the int64 branch

zend_do_return -> zend_emit_final_return

Remove DUMMY_STRINGL

What is that for?

Fix leaks

Must find a good way to handle constant expressions...

Use arena allocator (currently leaky!)

Expose ast via CG(ast)

Partial NS port (semicolon, no errors)

Port __TRAIT__ and __CLASS__ to AST

Port __METHOD__

Port __FUNCTION__ to AST

Handle trait __CLASS__ in parser

zend_stack_top() now returns pointer directly

Don't allocate zend_stack elements individually

Instead allocate a vector of elements. Size must now be specified
on initialization rather than on push.

Cleanup (2-nd round)

Fixed memory leak
