crank up cache limits
delete pages that are older than one hour, and scan the cache only once every five minutes. The previous defaults were a bit too much conservative.
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.
move util.c declarations in utils.h
it's not spelled `util.h' because otherwise it'd get included instead of /usr/include/util.h
simplify the caching API
- don't expose the evbuffer where we store the cached page - cache to/from tabs instead of buffers
add an in-memory cache store
