89ecd73a04 Make ast->children a uint
Future optimization: only use uint for dynamic lists and use a

f9927a6c97 Merge mainstream 'master' branch into refactoring
During merge I had to revert:
	Nikita's patch for php_splice() (it probably needs to be applyed again)
	Bob Weinand's patches related to constant expression handling (we need to review them carefully)
	I also reverted all our attempts to support sapi/phpdbg (we didn't test it anyway)

e96073b1e4 Moved zend_literal->cache_slot right into zval.
It should be accessed using Z_CACHE_SLOT() macro.
zend_literal structure is removed.
API functions that accepted pointer to zend_literal now accept pointer to zval or cache_slot directly.
Calls of such functiond that now accept cache_slot need to be changed to pass -1 instead of NULL.

20f2e5986e Fix ZTS build
This only makes it compile, it doesn't actually work, presumably

d3b484df82 Disallow use of positional args after unpacking
This commit disallows the use of trailing positional arguments
after argument unpacking was used. The following calls are no
longer valid:

    fn(...$array, $var);
    fn(...$array1, $var, ...$array2);

However, all of the following continue to be valid:

    fn($var, ...$array);
    fn(...$array1, ...$array2);
    fn($var, ...$array1, ...$array2);

The reason behind this change is a stack allocation issue pointed
out by Dmitry: As of PHP 5.5 the stack necessary for pushing
arguments is precomputed and preallocated, as such the individual
SEND opcodes no longer verify that there is enough stack space.
The unpacked arguments will occupy some of that preallocated
space and as such following positional arguments could write past
a stack page boundary.

An alternative resolution for this issue is to ensure that there
is enough space for the remaining arguments in the UNPACK opcode.
However making this allocation precise (rather than using a
conversative over-estimate) would require some effort. Given that
this particular aspect of the feature wasn't very popular in the
first place, it doesn't seem worth the effort.

2eae187949 Store arg_num in fcall entry
Instead of storing the argument number in the znode of the parameter
list, store it in fcall->arg_num. This mainly cleans up the parameter
parsing code, which previously had to duplicate all rules (this
becomes more excessive as more features are added, e.g. named params
would already require a minimum of 14 rules...)

cefa7f8d08 Introduce zend_function_call_entry structure
Instead of directly pushing the zend_function* onto the
function_call_stack, push this structure. This allows us to store
additional data on this stack.
