Strip down Travis CI support toward future deprecation:

* Remove all builds except cmake gcc & clang debug.
* Time some dependency and build operations, using a custom format to avoid
  interfering with other timers.
* Use Travis's "trusty" infrastructure.
* Install more dependencies via apt.
* Update boost version to 1.65.1.
* Do not run unit tests under gdb - several security features prevent
  it from running correctly.
* Run test job with two processes.
