Move OCSP stapling information from a per-certificate store
(ex_data attached to an X509 *) to a per-server hash which is
allocated from the pconf pool. Fixes PR 54357, PR 56919 and
a leak with the certinfo_free cleanup function (missing
OCSP_CERTID_free).

* modules/ssl/ssl_util_stapling.c: drop certinfo_free, and add
  ssl_stapling_certid_free (used with apr_pool_cleanup_register).
  Switch to a stapling_certinfo hash which is keyed by the SHA-1
  digest of the certificate's DER encoding, rework ssl_stapling_init_cert
  to only store info once per certificate (allocated from the pconf
  to the extent possible) and extend the logging.

* modules/ssl/ssl_private.h: adjust prototype for
  ssl_stapling_init_cert, replace ssl_stapling_ex_init with
  ssl_stapling_certinfo_hash_init

* modules/ssl/ssl_engine_init.c: adjust ssl_stapling_* calls
