New releases of OpenSSL will only allow secure renegotiation by

default.  Add an "SSLInsecureRenegotiation" directive to enable
renegotiation against unpatched clients, to ease transition:

* modules/ssl/ssl_private.h (struct SSLSrvConfigRec): Add
  insecure_reneg field.

* modules/ssl/ssl_engine_config.c (ssl_config_server_new,
  ssl_config_server_merge): Handle the insecure_reneg flag.
  (ssl_cmd_SSLInsecureRenegotiation): New function.

* modules/ssl/ssl_engine_init.c (ssl_init_ctx_protocol): Set the
  SSL_OP_ALLOW_UNSAFE_LEGACY_RENEGOTIATION option if insecure_reneg is
  enabled.

* modules/ssl/ssl_engine_kernel.c (ssl_hook_Access): Log level of
  support for secure reneg.

* modules/ssl/mod_ssl.c: Add the directive definition.
