HT functions that modify the array now assert that rc=1. As we don't
respect this COW constraint everywhere, either for a good reason or
because fixing it would take more work, we provide an escape hatch
in the form of HT_ALLOW_COW_VIOLATION(ht). If this macro is called
assertions on this ht are disabled. The macro is a no-op in release
mode.

The following changes are made:
- _SERVER/_ENV only has HTTP_PROXY if the local environment has it,
and only one from the environment.
- getenv('HTTP_PROXY') only returns one from the local environment
- getenv has optional second parameter, telling it to only consider
local environment
Now each HashTable is also zend_array, so it's refcounted and may be a subject for Copy on Write
zend_array_dup() was changed to allocate and return HashTable, instead of taking preallocated HashTable as argument.
So we can use it there as well...
For now I've retained the zend_smart_str_public.h header, though
it would probably be better to just move that one struct into
zend_types.h.
* call-frame:
Simplify call-frame handling
Removed EG(active_symbol_table) and use corresponding value from EG(current_execute_data)
Use values from current_execute_data instead of globals where possible
Removed EG(called_scope) and use corresponding value from EG(current_execute_data)
Removed EG(in_execution). If EG(currentent_execute_data) is not NULL we are executing something.
Removed EG(opline_ptr) and use corresponding value from EG(current_execute_data)
Removed EG(active_op_array) and use corresponding value from EG(current_execute_data)
Uinified call frame handling for user and internal functions. Now EG(current_execute_data) always point to the call frame of the currently executed function.
Fixed cleanup of incompleytely passed parameters
Prohibited parameter redefinition
Fixed support for extra arguments in conjunction with variadiv argument. Use compile time flags to check if we call constructor and result of ZEND_NEW is used or not.
Fixed uninitialized variables
Optimization
Changed zend_execute_data layout to reduce memory overhead
Help C compilet to do the better job optimizing target code
Use fast comparison for (func->type == ZEND_USER_FUNCTION || func->type == ZEND_EVAL_CODE)
Keep extra args in the same VM stack segment (after all CV and TMP vars)
Refactoring: merge call_frame and end_execute_data into single data structure. Keep only single copy of each argument on VM stack (previously ZE kept two copies of each arguments for user functions)
Refactoring: use call_frames instead of call_slots
