Initial support for the Cross-Origin Resource Sharing specification.
This allows JavaScript to make requests across domain boundaries.
Also reviewed the filter example to get rid of the context and
the generic classes (we can actually use {WSF_REQUEST}.execution_variable
and {WSF_REQUEST}.set_execution_variable).

added `a_request_methods' argument to WSF_ROUTER_SELF_DOCUMENTATION_HANDLER.mapping_documentation
added similar argument to WSF_ROUTER_SELF_DOCUMENTATION_ROUTER_MAPPING.documentation
Renamed WSF_ROUTER_METHODS as WSF_REQUEST_METHODS
Enhanced WSF_REQUEST_METHODS with new has_... function
Added WSF_ROUTER_VISITOR and WSF_ROUTER_ITERATOR that may be useful to iterate inside the router.
we may improve the implementation of the router using those visitors in the future.
Improved the WSF_DEFAULT_RESPONSE to embedded suggested items (typically based on pseudo self documented router)
Cleaned the WGI_CHUNKED_INPUT_STREAM and provides access to last extension, last trailer, ...
Improved WSF_TRACE_RESPONSE to support tracing chunked input back to the client.
Now put_chunk does not support anymore empty chunk, and thus does not call put_chunk_end if ever it is called with empty chunk content.
Fixed the `transfered_content_length' when dealing with chunk transfert encoding
- raw_header_data: like meta_string_variable
- read_input_data_into (buf: STRING)
- is_content_type_accepted (a_content_type: READABLE_STRING_GENERAL): BOOLEAN
Changed raw_input_data to return IMMUTABLE_STRING_8
Added WSF_METHOD_NOT_ALLOWED_RESPONSE
Added WSF_TRACE_RESPONSE to respond TRACE request
Now Not_found response return html content if the client accepts, other text/plain
Implemented TRACE response, and Method not allowed as implementation of WSF_ROUTED_SERVICE.execute_default
The logging filter is now part of EWF core (before it was only available in
the filter example) and can therefore be reused by others needing it.
Note that this is a first implementation. It can certainly be improved in
the future to support more fine grained logging.
Added smart handling of HEAD request.
Exported some internal features of WSF_REQUEST and WSF_RESPONSE to respectively WSF_REQUEST_EXPORTER and WSF_RESPONSE_EXPORTER
The documentation is built only on demand.
A mapping entry can be hidden for the documentation
One can change the status code when building itself the WSF_ROUTER_SELF_DOCUMENTATION_MESSAGE
Added WSF_ROUTER_MAPPING.associated_resource
Added WSF_ROUTER_SELF_DOCUMENTATION_HANDLER and WSF_ROUTER_SELF_DOCUMENTATION_MESSAGE to provide a self documentation for WSF_ROUTER (for now, only HTML)
