QUIC: packet processing refactoring.
All packet header parsing is now performed by ngx_quic_parse_packet()
function, located in the ngx_quic_transport.c file.
The packet processing is centralized in the ngx_quic_process_packet()
function which decides if the packet should be accepted, ignored or
connection should be closed, depending on the connection state.
As a result of refactoring, behavior has changed in some places:
- minimal size of Initial packet is now always tested
- connection IDs are always tested in existing connections
- old keys are discarded on encryption level switch
