*) mod_md: a new directive `MDStoreLocks` can be used on cluster
setups with a shared file system for `MDStoreDir` to order
activation of renewed certificates when several cluster nodes are
restarted at the same time. Store locks are not enabled by default.
Restored curl_easy cleanup behaviour from v2.4.14 and refactored
the use of curl_multi for OCSP requests to work with that.
