ci: Switch to Github Actions (#3152)

* WIP: Trying to make a new branch

* Create fuzzing.yml

* Update ci.yml

* Try using reviewdog for golangci-lint

* Only run lint on ubuntu

* Whoops, wrong matrix variable

* Let's try just ubuntu for the moment

* Remove integration tests

* Let's see what the tree looks like (where's the binary)

* Let's plant a tree

* Let's look at another tree

* Burn the tree

* Let's build in the right dir

* Turn on publishing artifacts

* Add gobin to path

* Try running golangci-lint earlier

* Try running golangci-lint on its own, with checkout@v1

* Try moving golangci-lint back into ci.yml as a separate job

* Turn off azure-pipelines

* Remove the redundant name, see how it looks

* Trim down the naming some more

* Turn on windows and mac

* Try to fix windows build, cleanup

* Try to fix strange failure on windows

* Print our the coerce reason

* Apparently $? is 'True' on Windows, not 1 or 0

* Try setting CGO_ENABLED as an env in yml

* Try enabling/fixing the fuzzer

* Print out github event to check, fix step name

* Fuzzer needs the code

* Add GOBIN to PATH for fuzzer

* Comment out fork condition, left in-case we want it again

* Remove obsolete comment

* Comment out the coverage/test conversions for now

* Set continue-on-error: true for fuzzer, it runs out of mem

* Add some clarification to the retained commented sections
