* PHP-5.6:
Updated UPGRADING for #38409
Updated NEWS for #38409
Added test case
Making ini parser typed - Added ZEND_INI_SCANNER_TYPED mode for parse_ini_string() and parse_ini_file() - Added NULL_NULL token to separate it from BOOL_FALSE and BOOL_TRUE - Added zend_ini_copy_typed_value() function for zval initialisation - Updated RETURN_TOKEN() to observe scanner_mode
Conflicts:

- Added ZEND_INI_SCANNER_TYPED mode for parse_ini_string() and parse_ini_file()
- Added NULL_NULL token to separate it from BOOL_FALSE and BOOL_TRUE
- Added zend_ini_copy_typed_value() function for zval initialisation
- Updated RETURN_TOKEN() to observe scanner_mode
Now one common stack to handle both, which stores znodes instead of
full oplines (foreach copy stack) or switch entries (switch cond
stack).
Also removed EG(start_op) while at it.
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.
This fixes bug #60097.
Before two global variables CG(heredoc) and CG(heredoc_len) were used to
track the current heredoc label. In order to support nested heredoc
strings the *previous* heredoc label was assigned as the token value of
T_START_HEREDOC and the language_parser.y assigned that to CG(heredoc).
This created a dependency of the lexer on the parser. Thus the
token_get_all() function, which accesses the lexer directly without
also running the parser, was not able to tokenize nested heredoc strings
(and leaked memory). Same applies for the source-code highlighting
functions.
The new approach is to maintain a heredoc_label_stack in the lexer, which
contains all active heredoc labels.
As it is no longer required, T_START_HEREDOC and T_END_HEREDOC now don't
carry a token value anymore.
In order to make the work with zend_ptr_stack in this context more
convenient I added a new function zend_ptr_stack_top(), which retrieves the
top element of the stack (similar to zend_stack_top()).
. zend_function.pass_rest_by_reference is replaced by
ZEND_ACC_PASS_REST_BY_REFERENCE in zend_function.fn_flags
. zend_function.return_reference is replaced by ZEND_ACC_RETURN_REFERENCE
in zend_function.fn_flags
. zend_arg_info.required_num_args removed. it was needed only for internal
functions. Now the first arg_info for internal function (which has special
meaning) is represented by zend_internal_function_info structure.
. zend_op_array.size, size_var, size_literal, current_brk_cont,
backpatch_count moved into CG(context), because they are used only during
compilation.
. zend_op_array.start_op is moved into EG(start_op), because it's used
only for 'interactive' execution of single top-level op-array.
. zend_op_array.done_pass_two is replaced by ZEND_ACC_DONE_PASS_TWO in
zend_op_array.fn_flags.
. op_array.vars array is trimmed (reallocated) during pass_two.
. zend_class_entry.constants_updated is replaced by
ZEND_ACC_CONSTANTS_UPDATED in zend_class_entry.ce_flags
. the size of zend_class_entry is reduced by sharing the same memory space
by different information for internal and user classes.
See zend_class_inttry.info union.
