* WIP: travis changes

Simplify Travis so it fails less often.

We don't need docker any more, let alone trusty and sudo, so simplifies
this, to just os: linux.

Mmark recently became able to create manual pages. This removed the
dependency on 'ronn' and just uses mmark (Go program).

Re-hookup Makefile.doc to generate the correct header mmark needs to
see and regenate them all.

Spot checking a few pages suggest they look good and actually better
than rendered with ronn, esp. lists in lists.

This was hard to do previously as we didn't hardcode this in the source,
but now with OWNERS files we can just generate this list.

Privacy wise this isn't worse than being listed in OWNERS file in the
first place. And it's a nice hat tip to the people making CoreDNS
better.

* Remove context.Context from request.Request

This removes the context from request.Request and makes all the changes
in the code to make it compile again. It's all mechanical. It did
unearth some weirdness in that the context was kept in handler structs
which may cause havoc with concurrently handling of requests.
