STREAM and CRYPTO frames have a similar encoding format. In particular, both of them have a variable-length integer Length field just before the frame payload. It is complex to determine the optimal Length value before copying the payload data in the remaining buffer space. As such, helper functions were implemented to calculate this. However, CRYPTO and STREAM frames encoding implementation were not completely aligned, which renders the code harder to follow. The purpose of this commit is to simplify CRYPTO and STREAM frames encoding. First, a new helper quic_int_cap_length() is defined which is useful to determine the optimal buffer room available if prefixed by a variable-length integer as Length field. Then, processing of both CRYPTO and STREAM frames is now nearly identical, based on this new helper function. Functions max_available_room() and max_stream_data_size() are now unused and are removed.
