chore(webfuse) Increase test coverage (#34)

* removes unnecessary code

* adds test of wf_status

* adds tests of wf_message

* adds tests of wf_message_queue

* changed branch of coverage badge to display correct results

* moves core tests into separate subdirectory

* increases coverage of timer test

* moves adapter specific tests into separate directory

* moves provider specific tests into separate directory

* adds tests of jsonrpc utilities

* adds tests of jsonrpc request

* adds test of jsonrpc response

* adds tests of jsonrpc server

* adds tests of jsonrpc proxy

* adds integration test (found some issues)

* disables problematic tests

* fixes resource leak: pending timer after cleanup proxy

* fixes order of cleanup to prevent processing pending requests after filesystem shut down

* fixes some memcheck and helgrind errors: initialization of lws_log; setup of client and server

* disabled a test

* fixes error in msleep utility

* fixes deadlock at IntegrationTest using valgrind

* removes unit test code from coverage report

* adds some integration tests

* makes badge show coverage of master

* fixes some coding style issues

* fixes eary trigger of is_connected (provider)

* fixes read error in 32 bit environments\n\ninode is always 64 bit, but variadic wf_impl_jsonrpc_proxy_invoke expects int
