Fix internal flags for MULTI / EXEC and PUB/SUB contexts.

Do not ask me why I was using 0x (the prefix for hexadecimal notation)
when what we really need here is 0b (the prefix for binary notation).
Really, everything was working by sheer coincidence.

Since 0b has been added in PHP 5.4, we rely on plain decimal numbers
to define our constants for now.

+- __FIX__: the internal flags used to track the state of PUB/SUB and MULTI/EXEC
