This reverts commit 9c14a8c002bb3396f9a7d9b2ba39969207f066ba.

* aruco_pose: Vendor opencv_contrib/aruco again

* builder: Add led packages

* builder: Remove unused builder code

* travis: Add native tests

* builder: Set permissions for standalone-install

* builder: Use -y for package installation

* builder: Add repo for standalone build

* builder: Use correct file types for standalone install

* aruco_pose: Accept rgb8 map images

* builder: Disable mjpg_streamer test

* aruco_pose: Allow rgb8 map images (again)

* builder: Re-add mjpgstreamer

* builder: Install tornado==4.2.1 for rosbridge_suite

* builder: Use more recent base image

These tests fail on a remote machine but seem to pass just fine on real hardware. Something must have changed between Kinetic and Melodic, and we must investigate more, but for now we just need a working image.

* aruco_pose: Remove unused vendored code

* selfcheck: Update systemd-analyze regex

* builder: Add opencv repository

* rosdep: Update package definitions for Melodic

* rosdep: Use proper yaml formatting

* travis: Remove unnecessary space

* docs: Reference Melodic wherever possible
