Subject: QUIC: ngx_quic_bpf module.

The quic kernel bpf helper inspects packet payload for DCID, extracts key
and routes the packet into socket matching the key.

Due to reuseport feature, each worker owns a personal socket, which is
identified by the same key, used to create DCID.

BPF objects are locked in RAM and are subject to RLIMIT_MEMLOCK.
The "ulimit -l" command may be used to setup proper limits, if maps
cannot be created with EPERM or updated with ETOOLONG.
