Dan Liew 8310fed528 [TravisCI] Implement TravisCI build and testing infrastructure for Linux 
The Linux builds rely on Docker (using Ubuntu 16.04LTS and Ubuntu
14.04LTS) to build and test Z3 so that builds are easily reproducible.

A build status button has been added to `README.md` so that it is
easy to see the current build status.

More documentation can be found in `contrib/ci/README.md`.

This implementation currently tests 13 different configurations. If
build times become too long we can remove some of them.

Although it would be nice to test macOS builds that requires
significantly more work so I have left this as future work.

Nikolaj Bjorner bfd1bbc136 Merge pull request #1111 from delcypher/fix_cxx_api_exceptions_gcc_4_8 
Unbreak Z3 C++ API exception support for GCC < 5.0.
 2017-06-25 16:10:23 -07:00
Dan Liew 42e0f8f9ce Unbreak Z3 C++ API exception support for GCC < 5.0. This was broken 
by 0b1d564509 .

Older versions of GCC do not define `__cpp_exceptions` which caused
exceptions to not be raised leading to unexpected failures. To fix
this also check the `__EXCEPTIONS` macro which is used by older GCC
versions.

Also `#undef` the `Z3_THROW` macro at the end of the header file
because this is an implementation detail that we don't want to leak
to clients.
