Apply Apache license to all .go source files (closes #1865)
I am not a lawyer, but according to the appendix of the license,
these boilerplate notices should be included with every source file.

59bf71c293 proxy: Cleanly shutdown health checks on restart (#1524)
* Add a shutdown function and context to staticUpstream so that running goroutines can be cancelled. Add a GetShutdownFunc to Upstream interface to expose the shutdown function to the caddy Controller for performing it on restarts.

* Make fakeUpstream implement new Upstream methods.

Implement new Upstream method for fakeWSUpstream as well.

* Rename GetShutdownFunc to Stop(). Add a waitgroup to the staticUpstream for controlling individual object's goroutines. Add the Stop function to OnRestart and OnShutdown. Add tests for checking to see if healthchecks continue hitting a backend server after stop has been called.

* Go back to using a stop channel since the context adds no additional benefit.
Only register stop function for onShutdown since it's called as part of restart.

* Remove assignment to atomic value

* Incrementing WaitGroup outside of goroutine to avoid race condition. Loading atomic values in test.

* Linting: change counter to just use the default zero value instead of setting it

* Clarify Stop method comments, add comments to stop channel and waitgroup and remove out of date comment about handling stopping the proxy. Stop the ticker when the stop signal is sent

463c9d9dd2 Fix data race for max connection limiting in proxy directive. (#1438)
* Fix data race for max connection limiting in proxy directive.

The Conns and Unhealthy fields are updated concurrently across all active
requests.  Because of this, they must use atomic operations for reads and
writes.

Prior to this change, Conns was incremented atomically, but read unsafely.
Unhealthly was updated & read unsafely.  The new test
TestReverseProxyMaxConnLimit exposes this race when run with -race.

Switching to atomic operations makes the race detector happy.

* oops, remove leftover dead code.

8048e9c3bc proxy: Added unbuffered request optimization
If only one upstream is defined we don't need to buffer the body.
Instead we directly stream the body to the upstream host,
which reduces memory usage as well as latency.
Furthermore this enables different kinds of HTTP streaming
applications like gRPC for instance.
