annotate src/event/ngx_event_quic.c @ 8183:6091506af0f7 quic

Aded the "ngx_quic_hexdump" macro. ngx_quic_hexdump0(log, format, buffer, buffer_size); - logs hexdump of buffer to specified error log ngx_quic_hexdump0(c->log, "this is foo:", foo.data, foo.len); ngx_quic_hexdump(log, format, buffer, buffer_size, ...) - same as hexdump0, but more format/args possible: ngx_quic_hexdump(c->log, "a=%d b=%d, foo is:", foo.data, foo.len, a, b);
