* modules/ssl/ssl_engine_vars.c (ssl_var_register): Take a pool

argument; determine library version strings once at startup.
(ssl_var_lookup_ssl_version): Drop 'pp' argument; use new global
variables rather than modifying process-global state in a function
which must be thread-safe.  (all callers changed)

* modules/ssl/mod_ssl.c (ssl_register_hooks): Pass pool to
  ssl_var_register.
