package/python-crossbar: adjust dependencies based on requirements-min.txt

This commit makes sure that the python-crossbar package pulls in the
right dependencies, based on the requirements-min.txt.

It does so by:

 - Changing the 0002-Remove-idna-requirement patch by a more thorough
   patch that drops all indirect dependencies from
   requirements-min.txt, making it easier to have a 1:1 mapping
   between lines in requirements-min.txt and Buildroot selects.

 - Changing the
   0003-crossbar-webservice-wap-use-markupsafe-instead-of-we patch to
   update requirements-min.txt to indicate the new MarkupSafe
   dependency. Here again, to have a 1:1 mapping between lines in
   requirements-min.txt and Buildroot selects.

 - Updating the Buildroot selects to match requirements-min.txt, with
   relevant comments when it does not.

 - Fixing up the Crossbar test case to no longer force autobahn to use
   umsgpack. Instead, we now use the default of msgpack that is
   expected by autobahn.

Fixes bug #14556, https://bugs.busybox.net/show_bug.cgi?id=14556.

+Subject: [PATCH] requirements-min.txt: drop indirect dependencies
+
+For some interesting reason, the crossbar maintainers have decided to
+include indirect dependencies in their requirements-min.txt, i.e
+dependencies that they don't use directly, but that packages they
+depend on themselves depend on.
+
+This makes the packaging in Buildroot confusing, as it means not all
+dependencies in requirements-min.txt should be taken into
+account. Also some of these indirect dependencies cause issues due to
+upper bounds set on the version (which is the case for idna and
+urllib3).
+
+This patch therefore clarifies the situation by removing such indirect
+dependencies from requirements-min.txt. As the patch is obviously not
+upstreamable, it will require some maintenance effort, but that effort
+is anyway already there to sort out direct dependencies from indirect
+dependencies when updating the Buildroot packaging for crossbar.
