[PATCH rdma-core 0/3] Fixes and package improvement to Travis CI

[Leon Romanovsky]

Hi,

This patchset comes from Alaa, who fixed two issues discovered during
his work to enable checks of distribution packages in Travis CI.
These fixes allowed us to add Ubuntu Artful to the list of checked
distributions.

[PATCH rdma-core 1/3] Fix compilation warnings when NDEBUG is set

[Leon Romanovsky]

From: Alaa Hleihel <alaa-VPRAkNaXOzVWk0Htik3J/w@public.gmane.org>

When NDEBUG is set (-DCMAKE_BUILD_TYPE=Release) and CFLAGS is set to
-Werorr, we get some compilation errors as the following:

rdma-core/libibverbs/neigh.c:378:13: error: variable 'rc' set but not used [-Werror=unused-but-set-variable]
     ssize_t rc;

[PATCH rdma-core 3/3] travis: Test Debian packaging under artful container

[Leon Romanovsky]

From: Alaa Hleihel <alaa-VPRAkNaXOzVWk0Htik3J/w@public.gmane.org>

This will be compiled with GCC 7 coming with Ubuntu artful.

Also, remove installations of GCC 7 and debian helpers from addons->apt
list in .travis.yml file as they are no longer required.

Finally, since we are removing a -Werror compilation test from buildlib/travis-build,
make sure that all builds performed by buildlib/cbuild will run with
-Werorr by adding it to CFLAGS environment variable.

Please do not apply this until we fix the root cause.

Debian and RH 32 bit builds should be built with SSE turned on, so
they may need some compiler options in their packaging files.

Otherwise all this code is totally useless.

Also, this condition should be a #warning print or some kind of cmake
failure as it is deeply undesired..

Please don't force -Werror for all cbuild runs.. We expect to get
unfixable warnings from some of the older containers like RH6.

Suggest a command line option to use when called by travis? Or why not
just set CFLAGS in travis in the first place?
