fixed autotests compilation
Added basic support for "Expect" http header
i.e:   WSF_REQUEST.http_expect: detachable READABLE_STRING_8

Added WSF_REQUEST.request_time_stamp: INTEGER_64
Added logger response wrapper, this is mainly to be able to save any response message to a file.
(debugging purpose)
Fixed sending of chunk, especially the ending where there is an optional Trailer, and a mandatory final CRLF
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
Fixed reading chunked input data
When retrieving data block by block, use 8_192 instead of 1_024 (since 1_024 is too small most of the time)
Fixed various assertions.
Improved autotests
Added target 'server' to be able to run the server outside the test process.
changed UUID since this is the same a restbuckCRUD example.
Fixed WSF_RESPONSE chunk transfer implementation
  and also the optional extension `a_ext' should now include the ';'
Now HTTP_HEADER is an ITERABLE [READABLE_STRING_8]
Fixed issue in WSF_REQUEST.read_input_data_into when the content is zero
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.
Updated documentation output
Breaking changes:
 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)
Fixed WSF_TRACE_RESPONSE which was overwritting previously prepared content.
Added a few library_target to .ecf to be able to build the tests/all-safe.ecf
that enables us to check quickly the compilation state of EWF, and also perform refactorying over many projects.
Added comment to self documentation features
Added openshift connector classes (for experimentation)
updated conneg .ecf
Added support for server name
Merge branch 'master' of https://github.com/Eiffel-World/EiffelWebNino
updated doc related to git
Added support for server_name in nino, and openshift
