In case of long header packets, dcid length was not read correctly.

While there, macros to parse uint64 was fixed as well as format specifiers
to print it in debug mode.

Thanks to Gao Yan <gaoyan09@baidu.com>.

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.
