From: Frediano Ziglio <fziglio@xxxxxxxxxx>
Define COMPRESS_xx/UNCOMPRESS_xx macros in a more similar way between
quic_tmpl.c and quic_rgb_tmpl.c using channel suffixes. Instead of
having #define COMPRESS(channel) do_something(channel), we'll now have
#define COMPRESS(channel) do_something(channel_##channel), and call it
with COMPRESS(a)
