We now use the soversion to set compatibility_version and
current_version by default. This is the only sane thing we can do by
default because of the restrictions on the values that can be used for
compatibility and current version.
Users can override this value with the `darwin_versions:` kwarg, which
can be a single value or a two-element list of values. The first one
is the compatibility version and the second is the current version.

* Currently, RPATHs coming from dependencies and
`build_rpath` provided by the user might contain
the same path. Apple's `install_name` tool is
allergic to providing the same argument twice
when removing RPATHs:
error: install_name_tool: "-delete_rpath /usr/lib" specified more than once
Alex Băluț reported that on OS X libfoo.0.dylib cannot be found as -lfoo by the
linker, and you must use -lfoo.0 instead. Add a test for this so the CI can
catch such problems. The next commit will contain the fix.
Also add new tests for the platform-specific and compiler-specific
versioning scheme.
A rough summary is:
1. A bug in how run_tests.py:validate_install checked for files has been
fixed. Earlier it wasn't checking the install directory properly.
2. Shared libraries are no longer installed in common tests, and the
library name/path testing is now done in platform-specific tests.
3. Executables are now always called something?exe in the
installed_files.txt file, and the suffix automatically corrected
depending on the platform.
4. If a test installs a file called 'no-installed-files', the installed
files for that test are not validated. This is required to implement
compiler-specific tests for library names/paths such as MSVC vs MinGW
5. The platform-specific file renaming in run_tests.py has been mostly
removed since it is broken for shared libraries and isn't needed for
static libraries.
6. run_tests.py now reports all missing and extra files. The logic for
finding these has been reworked.
