Jon Shallow 2900f72a64 Make coap_subscription_t and coap_endpoint_t opaque to applications ...

include/coap2/coap_subscribe_internal.h and
include/coap2/coap_session_internal.h contain the information not exposed
to applications.

This internal information was moved out of the respective
include/coap2/subscribe.h and include/coap2/coap_session.h files comprising of
the coap_subscription_t and coap_endpoint_t definitions.

To ease inter .h file dependencies, a new file
include/coap2/coap_forward_decls.h is added to include forward declarations
for both libcoap and applications.

Makefile.am:

Include include/coap2/coap_*internal.h as files for distribution, but not
installed for applications to use.
Include include/coap2/coap_forward_decls.h, so it is installed for
applications.

include/coap2/coap.h.in:

Include "coap_forward_decls.h"

include/coap2/coap_forward_decls.h: (New)

Forward declare structures and typedef the structures defined in
coap_internal.h.

include/coap2/coap_internal.h: (New)

Includes all the required #include files that libcoap internally needs.

include/coap2/coap_session_internal.h: (New)

Include the coap_endpoint_t information taken from
include/coap2/coap_session.h.

include/coap2/coap_session.h:

Remove coap_endpoint_t definition.

include/coap2/lwippools.h:

Add in coap_forward_decls.h and coap_internal.h to handle the LwIP memory
allocations.

include/coap2/resource.h:

Add in "block.h" to allow things to build.

include/coap2/coap_subscribe_internal.h: (New)

Include the coap_subscription_t information taken from
include/coap2/subscribe.h.

include/coap2/subscribe.h:

Remove coap_subscription_t definition.

libcoap-2.map:
libcoap-2.sym:

Updated, removing coap_subscription_init().

Add in '#include "coap_internal.h"' to the source files.
Remove other libcoap #include files.

win32/libcoap.vcxproj:
win32/libcoap.vcxproj.filters:

Update for Windows build (not tested).

examples/contiki/server.c:
src/coap_io.c:

Remove knowledge of endpoint from the server and update Contiki's
version of coap_run_once() to do the work instead.

Other structures (plus some internal required #defines) will follow as
separate PRs.
