Do we want any checking, such as whether this is non-NULL?
For example, patch 3 has:
-typedef void (*connection_close_function) (struct connection *)
__attribute__((__nonnull__ (1)));
+typedef void (*connection_close_function) (void);
which loses the compile-time checking that we have a non-NULL connection
parameter; so replacing a parameter passed through a nonnull attribute
with a macro that guarantees a nonnull result might be in our favor,
where we can leave explicit calls to threadlocal_get_conn() rather than
macro usage for the few callers that expect to handle the corner cases
where a threadlocal connection might not yet be set.
