> pn_data_grow() function looses half of the available data capacity.
> The following happens: when data overflows, pn_data_grow is invoked. It 
> increases data capacity 2 times and reallocates nodes array. Data capacity is 
> represented as uint16_t type and so when capacity reaches 32768 items, the 
> result of multiplication by 2 becomes 0. This makes realloc return null and 
> crashes the program.
