Session cache interface redesign, Part 7:

Clean up provider interface, removing use of mod_ssl-specific types:

* modules/ssl/ssl_private.h (modssl_sesscache_provider): Replace BOOL
  with apr_status_t, UCHAR with unsigned char; use 'unsigned int' for
  idlen; constify id arguments; remove pool argument from ->status.

* modules/ssl/ssl_scache_dc.c, modules/ssl/ssl_scache_memcache,
  modules/ssl/ssl_scache_shmcb.c, modules/ssl_scache_dbm.c: Update
  accordingly.

* modules/ssl/ssl_scache.c (ssl_scache_retrieve, ssl_scache_store):
  Adjust for BOOL->apr_status_t change.
  (ssl_ext_status_hook): Update for dropped pool argument.
