config is stack allocated now + some code improvements (see details)

* for easier memory manegement, the entire sp_config struct was merged into snuffleupagus_globals and allocated on stack where possible
* SNUFFLEUPAGUS_G() can be written as SPG(), which is faster to type and easier to read
* execution_depth is re-initialized to 0 for each request
* function calls with inline string and length parameters consistently use ZEND_STRL instead of sizeof()-1
* execution is actually hooked if recursion protection is enabled
* some line breaks were removed to make the code more readable
