Closes #3564

Invoking the maintainer intended COPYRIGHTYEAR check for everyone
in the PR pipeline is too invasive, especially at the turn of the
year when many files get affected. Remove and leave it as a tool
for maintainers to verify patches before commits.

This reverts f7bdf4b2.

After discussion with: Daniel Stenberg

The extended warning for checking incorrect COPYRIGHTYEAR is quite
expensive to run, so rather than expecting every developer to do it
we ensure it's turned on locally for Travis.

on Linux. To make sure the test suite runs with its newly build tool and
doesn't require an external one present.

Due to an issue with travis
(https://github.com/travis-ci/travis-ci/issues/9956) we've been using
Xcode 9.2 for darwinssl builds for a while. Now xcode 10 is offered as
an alternative and as it builds curl+darwinssl fine that seems like a
better choice.

This works now and precise is in the process of being decommissioned.

This is a workaround for an unsolved travis issue that is causing CI
instances to sporadically fail due to 'unable to connect' issues during
apt stage.

Uses a separate build without --enable-debug and no valgrind.

The debug option causes far too many warnings in boringssl's headers
(C++ comments, trailing commas etc).  Valgrind triggers some false
positive errors in thread-local data used by boringssl.

Closes #2118

We don't expect any steps to fail in travis. Exit the script if they do.

Closes #1966

Use the external curl-fuzzer repository for fuzzing.
