Previously we had "make check" launched whenever DISTCHECK was
false.  Now we'd like to turn it off in a few other circumstances,
like running chutney.  Maybe stem too?

And fix a comment.

See:
https://gcc.gnu.org/onlinedocs/gcc/Gcov-Data-Files.html#Gcov-Data-Files

Since we have moved coveralls to the script target the entire build will
now fail if coveralls fail. We handle it more gracefully by echo'ing the
failure instead of doing a hard-failure.

This should ensure that GCDA files are never entering the cache of
Travis CI.

Use the Travis Homebrew addon to install packages on macOS. The package
list is the same, but the Homebrew addon does not do a `brew update` by
default.

This makes builds faster, at the cost of using slightly older packages.

Implements ticket 27738.

When we use echo in Travis, don't pass a --flag as the first argument.

Fixes bug 27418; bugfix on 0.3.4.7-rc.

When a Travis build fails, and showing a log fails, keep trying to
show the other logs.

Fixes bug 27453; bugfix on 0.3.4.7-rc.

It's redundant, because all the non-default builds use gcc on Linux.

Tor 0.2.9 needs extra help to find OpenSSL on macOS.

Part of 24629.

Creating the configure flags once avoids inconsistent flags
between configure and distcheck configure.

Echoing the flags helps developers work out what configure is
doing.

(Backported to 0.2.9 and later as a precaution.)

Fixes 27088 on 0.3.4.1-alpha, adds logging in previous releases.

Also:
* explain why we don't install zlib

Part of 24629.

Build on all compilers:
* default options + hardening

Build on gcc:
* coverage (+ no hardening)
* distcheck
* no hardening

Add some extra logging:
* tail config.log on failure
  (config.log is too long for travis to render)

Put the config in a more logical order
* Sort config items in chronological order
* Put related items together

Apparently we weren't building with either libcap or libseccomp on
Travis.  Install libcap-dev and libseccomp-dev in .travis.yml.  Closes
ticket 26560.

When Travis CI runs make distcheck, test-suite.log doesn't exist in
the expected place.  Add a new make target to show this file and use
it when DISTCHECK=yes in .travis.yml.  Fixes bug 25814; bug not in any
released Tor.

Implements 25814.

Closes ticket 25818.

Add some commented-out allow_failures clauses to make it easier to
temporarily allow less-critical sub-builds to fail while still
reporting success.

Travis CI deployed a change that disables ptrace capabilities in
container builds, which prevents LeakSanitizer on clang from working
properly.  Set "sudo: required" to force non-container builds for
clang and work around this.

(cherry picked from commit 8f8689f70235dc19cbc5092ea148af5772a9cdc3)

 * CHANGE .travis.yml so that commands for different purposes (e.g. getting
   dependencies, building, testing) are in separate config lines and sections.
 * CHANGE .travis.yml to use their mechanism for installing dependencies via
   apt. [0]  This also allows us to not need sudo (the "sudo: false" line).
 * CHANGE Travis CI tests (the "script:" section) to build and run tests in the
   same manner as Jenkins (i.e. with --enable-fatal-warnings and
   --disable-silent-rules and run `make check`).
 * ADD Travis configuration to do all the target builds with both GCC and clang.
 * ADD make flags to build with both of the cores available.
 * ADD notifications for IRC, and configure email notifications (to the author
   of the commit) only if the branch was previously building successfully and
   the latest commit broke it.
 * ADD the ability to run the Travis build matrix for OSX as well, but leave it
   commented out by default (because it takes roughly ten times longer, due to a
   shortage of OSX build machines).
 * ADD Travis config option to cancel/fail the build early if one target has
   already failed ("fast_finish: true").
 * ADD comments to describe what our Travis config is doing and why it is
   configured that way.

suites both with and without the rust components.
