term_to_binary use all 32 bits of INTEGER_EXT
Earlier, external format INTEGER_EXT was only produced for 28-bit
signed integers. Now full 32-bit signed integers are produced as
INTEGER_EXT to avoid the more costly SMALL_BIG_EXT format. Both old
and new code can read 32-bit INTEGER_EXT.
Also fixed integer encoding bugs in erl_interface erl_encode/erl_decode.
(Thanks to Alexander Demidenko for reporting)
