A Whole buncha stuff, mostly bug fixing...

- Make constants case-sensitive, conforming with the rest of PHP &
	the C API.
	- Make module compatible with thread safety features.
	- open_listen_sok() -> open_listen_sock()
	- Remove ext_skel comments
	- Get rid of the ZVAL macro and replace with the correct Z_*_*
	macros
	- declare all functions local to the file as static.
	- Remove empty PHP_MSHUTDOWN() function.
	- Removed confirm_sockets_compiled()
	- Changed RETVAL_* macro's to RETURN_* macro's eliminating errors
	with incorrect return values and a potential leak/crash or two.
	- functions that return void, actually return void
	- Replaced 'long' in the prototypes with 'int'
	- Fixed fd_zero() function, it gave a WRONG_PARAM_COUNT when you
	gave it the proper parameter count.
	- Changed the way an arbitrary number of parameters were accessed
	from build_iovec() to use the Zend API.
	- Added socketpair() and shutdown() functions.
