Removed memory allocations from encryption code. + ngx_quic_encrypt(): - no longer accepts pool as argument - pkt is 1st arg - payload is passed as pkt->payload - performs encryption to the specified static buffer + ngx_quic_create_long/short_packet() functions: - single buffer for everything, allocated by caller - buffer layout is: [ ad | payload | TAG ] the result is in the beginning of buffer with proper length - nonce is calculated on stack - log is passed explicitly, pkt is 1st arg - no more allocations inside + ngx_quic_create_long_header(): - args changed: no need to pass str_t + added ngx_quic_create_short_header()
