@param p Pointer to input data block.
@paramout q Location to store an updated value for p
@return The integer value, or zero if the type code was not valid.
Reads a one-byte type code from @p p, and uses it to decode an integer
value from the following bytes in @p p.
If the type is not one of BCF_BT_INT8, BCF_BT_INT16 or BCF_BT_INT32, zero
will be returned and @p *q will unchanged. Otherwise, the integer value will
be returned and @p *q will be set to the memory location immediately following
the integer value.
Cautious callers can detect invalid type codes by checking that *q has
actually been updated.
