Subject: Fixed casting warnings in trees.c with count being int and freq being uint16_t.

Fixed casting warnings in trees.c with count being int and freq being uint16_t.
Changed to use uint16_t for all counting variable types.

  trees.c(431,45): warning C4244: '+=': conversion from 'int' to 'uint16_t', possible loss of data
