commit a96922a16759643ba6a0bc3d9781e97fedbf1107
from: Omar Polo <op@omarpolo.com>
date: Tue Jan 11 22:03:54 2022 UTC

drop useless struct

instead of keeping the struct mcache that's private to mcache.c and
used only once, just define its fields as (static) variables.  While
here, mark as static also gemtext_prefixes.
