nginx: src/event/ngx_event_quic_protection.c annotate

annotate src/event/ngx_event_quic_protection.c @ 8651:dbad2d6d1898 quic

QUIC: removed ngx_quic_hexdump() macro. Instead, appropriate format specifier for hexadecimal is used in ngx_log_debug(). The STREAM frame "data" debug is moved into ngx_quic_log_frame(), similar to all other frame fields debug.
