This patch introduces the "index off;" directive for freenginx, but I
also had to modify other parts of the code to ensure this new
directive behaves correctly.
When "off" is applied in the config and an HTTP access occurs, a
message appears in the error_log: "directory index of ".../" is
forbidden". In this context, I believe this message is not
particularly relevant for the error_log. So, I added a flag to the
core called "log_forbidden", which works similarly to "log_not_found".

As a result, instead of modifying only "ngx_http_index_module.c", I
ended up changing four files:
  * src/http/ngx_http_core_module.c
  * src/http/ngx_http_core_module.h
  * src/http/modules/ngx_http_access_module.c
  * src/http/modules/ngx_http_index_module.c

I would appreciate it if the code could be reviewed. Any feedback or
suggestions are welcome.

Thank you in advance for the opportunity to submit this patch.
