462f8861f4 gcoap: Suppress retransmissions when ACK was received 
This introduces an additional state to the COAP_MEMO_* series to avoid
enlarging the memo struct needlessly. While they are documented
publicly, practically only the COAP_MEMO_TIMEOUT and COAP_MEMO_RESPONSE
are used in communication with the application, as a
gcoap_request_memo_t is only handed out in that state.

f32d758819 gcoap: Prepare to cease retransmission 
The actual implementation will follow in a separate commit, this does
the groundwork and sets the intention.

ff00d66d69 gcoap: Process CON responses 
This generalizes the existing code for answering CoAP pings into general
message-layer responses. Such responses are now also sent as a reaction
to CON responses, which can otherwise follow the same code path as
existing other responses.

As a side effect, issues that would crop up when responding to odd empty
requests that have token length set are resolved.

6350d22bc9 net/gcoap: Register additional resources head-first 
This simplifies (written and compiled) code by doing a head rather than
a tail insertion of the new listener into gcoap's list.

As handling of listeners without a link_encoder is now fixed,
gcoap_get_resource_list can handles this now without having to manually
skip over the .well-known/core handler (which is not the first entry any
more now).

Incidentally, this allows the user to install a custom handler for
.well-known/core, as the default handler is now evaluated last.

e3db58f013 net/gcoap: Avoid endless loop on error 
The NULL case can not regularly be reached (because regularly
gcoap_register_listener sets thel link_encoder to a default one), but if
it is (eg. because an application unsets its link_encoder to hide a
resource set at runtime), the existing `continue` is a good idea (skip
over this entry) but erroneously created an endless loop by skipping the
advancement step.

treewide: change prefix for generated Kconfig symbols. 
This changes the prefixes of the symbols generated from USEMODULE and
USEPKG variables. The changes are as follow:

   KCONFIG_MODULE_ => KCONFIG_USEMODULE_
   KCONFIG_PKG_ => KCONFIG_USEPKG_
   MODULE_ => USEMODULE_
   PKG_ => USEPKG_
