Prior to r1877345 mc->pPool was the process pool (s->process->pool).
Drop the field from SSLModConfigRec and use pconf instead (where

* modules/ssl/ssl_engine_kernel.c (ssl_callback_DelSessionCacheEntry):
  Explicitly (and probably unsafely) use the process pool.

* modules/ssl/ssl_engine_config.c (ssl_cmd_SSLRandomSeed): Use
  cmd->pool to allocate paths.

* modules/ssl/ssl_engine_init.c (ssl_init_Module): Use pconf
  to allocate the keylog_file.

* modules/ssl/ssl_engine_vars.c (ssl_var_lookup): Drop lookup
  of SSLModConfigRec and use s->process->pool when no pool is
  passed.
