SPA POD parser: fix several integer overflows

Browse source 
This fixes several integer overflow problems in the POD parser, as well
as fixing a returns-twice warning from GCC and integer truncation
problems in SPA_FLAG_CLEAR and SPA_ROUND_DOWN_N.  The integer overflows
can result in a tiny POD being treated as a huge one, causing
out-of-bounds reads.
