Use android-library, streamline dav4jvm

[tobiasKaminsky]

This uses

• Switching to dav4jvm android-library#881
• which uses [WIP] Add SEARCH and PROPPATCH bitfireAT/dav4jvm#3

This way we can streamline all our dav4jvm classes (and later also our okhttp3 client)

• write test

For later:

• remove BrowserFile

As always, early feedback is appreciated :-)

I currently get a crash at startup;

I suspect this is due to competing okhttp lib versions?

[tobiasKaminsky]

True. It works when I change it to http 5.x branch.
Not sure about any side effects…
