e0dbd02513
Summary: This patch introduces a header "dylib.h" which can be used in tests to handle shared libraries semi-portably. The shared library APIs on windows and posix systems look very different, but their underlying functionality is relatively similar, so the mapping is not difficult. It also introduces two new macros to wrap the functinality necessary to export/import function across the dll boundary on windows. Previously we had the LLDB_TEST_API macro for this purpose, which automagically changed meaning depending on whether we were building the shared library or the executable. While convenient for simple cases, this approach was not sufficient for the more complicated setups where one deals with multiple shared libraries. Lastly it rewrites TestLoadUnload, to make use of the new APIs. The trickiest aspect there is the handling of DYLD_LIBRARY_PATH on macos -- previously setting this variable was not needed as the test used @executable_path-relative dlopens, but the new generic api does not support that. Other systems do not support such dlopens either so the test already contained support for setting the appropriate path variable, and this patch just makes that logic more generic. In doesn't seem that the purpose of this test was to exercise @executable_path imports, so this should not be a problem. These changes are sufficient to make some of the TestLoadUnload tests pass on windows. Two other tests will start to pass once D77287 lands.
