Consistently use ../../.. as a fallback for $abs_top_srcdir in
test_rust.sh.

cargo will use the user's $CARGO_HOME, or $HOME/.cargo by default.

Fixes bug 26497; bugfix on 0.3.1.5-alpha.

Preparation for 26497.

Backports parts of the 0.3.3 travis config.

Part of 24629.

Forward-ports parts of the 0.3.2 travis config on top of the 0.2.9
merge.

Also:
* build rust on clang and gcc, Linux and macOS
* build combinations of non-default options on gcc Linux
* exclude broken builds
* log the rustup version

Forward-ports parts of the 0.3.2 travis config on top of the 0.2.9

Subsequent commits will restore 032 functionality.

Implements 27087.

Part of ticket 26952.

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

Part of 24629.

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

The seccomp rule for the openat syscall checks for the AT_FDCWD
constant. Because this constant is usually a negative value, a
cast to unsigned int is necessary to make sure it does not get
converted to uint64_t used by seccomp.

Conditionalize the pragma that temporarily disables
-Wunused-const-variable.  Some versions of gcc don't support it.  We
need to do this because of an apparent bug in some libzstd headers.

Improve the log message when connection initiators fail to authenticate
direct connections to relays.

Instead, log a protocol warning when single onion services or
Tor2web clients fail to authenticate direct connections to relays.
