Add Catch framework for testing embedding support and C++-side features At this point, there is only a single test for interpreter basics. Apart from embedding itself, having a C++ test framework will also benefit the C++-side features by allowing them to be tested directly.

Miscellaneous travis-ci updates/fixes - For the debian/buster docker build (GCC 7/C++17) install and use the system `catch` package; this also renames "COMPILER_PACKAGES" to "EXTRA_PACKAGES" since it now contains a non-compiler package. - Add a status message indicating the catch version being used for compiling the embedded tests - Simplify some bash code by using VAR+=" foo" to append (rather than VAR="${VAR} foo" - Fix CMAKE_INCLUDE_PATH appending: it was prepending the ':' but not the existing $CMAKE_INCLUDE_PATH value and so would end up with ":/eigen-path" if CMAKE_INCLUDE_PATH was already set. (This wasn't bug that was actually noticed since currently nothing else sets it).

Fix GIL release and acquire when embedding the interpreter Fixes a race condition when multiple threads try to acquire the GIL before `detail::internals` have been initialized. `gil_scoped_release` is now tasked with initializing `internals` (guaranteed single-threaded) to ensure the safety of subsequent `acquire` calls from multiple threads.

Fix segfault when reloading interpreter with external modules (#1092) * Fix segfault when reloading interpreter with external modules When embedding the interpreter and loading external modules in that embedded interpreter, the external module correctly shares its internals_ptr with the one in the embedded interpreter. When the interpreter is shut down, however, only the `internals_ptr` local to the embedded code is actually reset to nullptr: the external module remains set. The result is that loading an external pybind11 module, letting the interpreter go through a finalize/initialize, then attempting to use something in the external module fails because this external module is still trying to use the old (destroyed) internals. This causes undefined behaviour (typically a segfault). This commit fixes it by adding a level of indirection in the internals path, converting the local internals variable to `internals **` instead of `internals *`. With this change, we can detect a stale internals pointer and reload the internals pointer (either from a capsule or by creating a new internals instance). (No issue number: this was reported on gitter by @henryiii and @aoloe).
