ee2a7c7d41 Fixed disallowal of array usage in constants at run-time
Added at the same time the possibility of array dereferencing
to complete the set of features (useful application of arrays in constants)

592677d810 Fix intl build
Turns out that you can't use implicit void pointer casts if intl
is compiled.

fc16b92313 Fix bug #46311: Pointer aliasing issue results in miscompile on gcc4.4
The code violated the strict aliasing restriction, because it
dereferenced the same pointer as zval** once and as void**
afterwards. Now both occurances dereference void** and cast to
zval* in the former case.

70f83f35d0 . The VM stacks for passing function arguments and syntaticaly nested calls were merged into a single stack. The stack size needed for op_array execution is calculated at compile time and preallocated at once. As result all the stack push operatins don't require checks for stack overflow any more.
. Generators implementation was improved using the new VM stack. Now it's a bit more clear and faster.

c9709bfbd7 Remove asterix modifier (*) for generators
Generators are now automatically detected by the presence of a `yield`
expression in their body.

This removes the ZEND_SUSPEND_AND_RETURN_GENERATOR opcode. Instead
additional checks for ZEND_ACC_GENERATOR are added to the fcall_common
helper and zend_call_function.

This also adds a new function zend_generator_create_zval, which handles
the actual creation of the generator zval from an op array.

I feel like I should deglobalize the zend_create_execute_data_from_op_array
code a bit. It currently changes EG(current_execute_data) and
EG(opline_ptr) which is somewhat confusing (given the name).

f169b26dd7 Fix backtraces and func_get_args()
To make the generator function show up in backtraces one has to insert an
additional execute_data into the chain, as prev_execute_data->function_state
is used to determine the called function.

Adding the additional stack frame is also required for func_get_args(), as
the arguments are fetched from there too. The arguments have to be copied
in order to keep them around. Due to the way they are saved doing so is
quite ugly, so I added another function zend_copy_arguments to zend_execute.c
which handles this.

4aab08b64c Properly free resources when generator return value not used
To keep things clean two new functions are introduced:

zend_clean_and_cache_symbol_table(HashTable *symbol_table)
zend_free_compiled_variables(zval ***CVs, int num)

f627be5254 Add support for executing a zend_execute_data
This adds another function execute_ex(), which accepts a zend_execute_data
struct to run (contrary to execute(), which accepts a zend_op_array from
which it initialized the execute_data).

This needs a bit more cleanup.

6c158374ba exit_on_timeout patch
After the sigsetjmp change, this is patch #2 in an effort to get some
sanity restored to signal handling in PHP.

This patch does two things.  First, it makes it possible to reset the
timeout without resetting the signal handlers.  This is important for
cases where an extension may have deferred signals in its MINIT in order
to implement critical sections. It also lays the groundwork for cleaning
up our signal handling and perhaps eventually implementing our own
signal deferring mechanism so we can have true critical sections.

The second thing this does is to make it possible to terminate the current
child process (only for Apache1 at the moment) on a timeout.  There are
a number of extensions that are unhappy about being longjmp'ed out of
and when this happens on a timeout they are left in an inconsistent state.
By turning on exit_on_timeout you can now force the process to terminate
on a timeout which will clean up any hanging locks and/or memory left
hanging after the longjmp.
