V5: Split the patch.
V4: Fix rang check error in assert base on Mark's review
V3: Clean the code logic base on Michael's review.
V2: Add set_ue_golomb_long() to support 32bits UE golomb and update the unit test.

Subject: [PATCH V5 1/4] lavc/golomb: add value range comment for
 set_ue_golomb().

set_ue_golomb just support 2^16 - 2 at most, becase this function call
put_bits, and put_bits just support write up to 31 bits, when write 32
bit in put_bits, it's will overwrite the bit buffer, and the default
assert level is 0, the av_assert2(n <= 31 && value < (1U << n)) in
put_bits can not be trigger runtime.
