Remove code to support per-dir-CA configuration which relies on a

function which was never included in OpenSSL:

* acinclude.m4: Remove test for fictional function.

* modules/ssl/ssl_engine_kernel.c (ssl_hook_Access): Remove code.

* modules/ssl/ssl_engine_config.c (MODSSL_SET_CA): Remove unused
  macro.  (ssl_cmd_SSLCACertificatePath,
  ssl_cmd_SSLCACertificateFile): Fail if per-dir-CA is configured.
