Jon Shallow f026f5701e client+server: Reduce code size by building libcoap for client or server only
Add in new ./configure options --enable-client-mode or
--enable-server-mode which by default are enabled.

If --disable-client-mode is set, then disable all the client specific code.
[ COAP_CLIENT_SUPPORT is not defined ]

If --disable-server-mode is set, then disable all the server specific code.
[ COAP_SERVER_SUPPORT is not defined ]

Functions and variables are only #ifdef'd out in the include/coap3/*_internal.h
files.  They cannot be #ifdef'd out in the other include files as
COAP_CLIENT_SUPPORT and COAP_SERVER_SUPPORT are not available for application
compilations. The result of this is if, say, client only API functons are used
in a server application and COAP_CLIENT_SUPPORT is not defined, there will be
linking issues (missing functions).  Providing stub functions unecessarily
increases the code size.

For coap-server, if it is able to provide proxy support, requires both
COAP_SERVER_SUPPORT and COAP_CLIENT_SUPPORT to set up the ongoing sessions.
So, the build environment deliberatly sets SERVER_CAN_PROXY=0 if
COAP_CLIENT_SUPPORT is not available to allow linking.

Some of the tests have to be disabled if COAP_SERVER_SUPPORT or
COAP_CLIENT_SUPPORT is not set.

Jon Shallow 91737ccb46 versioning: Include api version in non-posix coap_config.h/coap.h .in files
Add in some new .in files, but still keep original files in distribution
files.

Essentially, use coap@LIBCOAP_API_VERSION@ (or equivalent) instead of
coap2. so resultant files have the correct value.

coap_config.h.lwip.in: (new)
coap_config.h.riot.in: (new)
include/coap2/coap.h.windows.in: (new)

As per https://gcc.gnu.org/onlinedocs/cpp/Search-Path.html, many of the
coap2/ prefixes are not required for #include, so these have been removed.

Make sure that the test suite accesses the latest source version of
coap@LIBCOAP_API_VERSION@/coap.h by creating a tests/test_common.h.in that
makes the correct tests/test_common.h which is included in all of the test
suite files.

Jon Shallow 0c031d7904 include: Move header files into libcoap namespace
I.E. '#include "mem.h"' becomes '#include "coap2/mem.h"'

This prevents header name clashes.

Olaf Bergmann a3da53d5e3 tests: use IPv4 in unit tests for robustness
As unit tests with IPv6 addresses keep failing on docker-based
travis CI, this changes reverts to IPv4 usage in following files:

Olaf Bergmann 4c38c6a7b2 test_{sendqueue,wellknown}.c: use new session-specific API
Sendqueue nodes and send operations now require a session object.
This modification calls coap_new_client_session() on a global
coap_context_t object to create a fake session on the loopback
interface.

Carsten Schoenert 63924379e3 testdriver: switch linking to the shared library
The testdriver was linked against the statically generated library of
libcoap. By this the testdriver will *always* find any symbols, no
matter if it is a private or public symbol.
Due this the testing behavior isn't the same as a user would use the
shared library and can get a potentially pitfall even if the testdriver
was successful.

Due previous changes to the public header the testdriver source needs
now the local header coap_config.h to find all needed functions so there
are small changes needed to the source files.
