Wconversion-related cleanup: split pbuf_header(s16_t) into pbuf_add_header(size_t) and pbuf_remove_header(size_t)

Browse Source 
The new functions both take size_t as increment/decrement argument instead of s16_t (which needed to be range-checked before conversion everywhere) - in most places, the direction (increment or decrement) is known anyway, so no need to encode it in a sign bit
