add clear_env option to FPM config

This makes it possible to leave the envoronment as is on startup and
pass all the variables to the workers.
The default value of clear_env is "yes", preserving previous behaviour.

rearrange the NEWS blocks a bit
move the default encoding NEWS entry to alpha3, as it was pushed after beta2 was tagged
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.
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...)
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 The following calls are no
longer valid: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.
