*: Remove appveyor, use travis windows support (#1919)

* *: Remove appveyor, use travis windows support

* cmd/dlv: Update TestOutput for Travis on Windows

* cmd/dlv: Skip TestGeneratedDoc in Travis on Windows

* Reduce number of jobs in matrix

We only really want to test the full arch/go matrix on Linux.
For every other os/arch/go combination, only run Go tip and the latest
supported version.
