Introduce the #define MAX_MARSHALLED_OBJECT_SIZE to be used for a size of
a byte buffer that is supposed to hold a marshalled OBJECT. The number
is not exact but provides for a 'safe' size of a buffer.
Add a test case to check that MAX_MARSHALLED_OBJECT_SIZE is sufficient.
The test case needs access to ANY_OBJECT_Marshal, which is only available
when -static can be used for linking since otherwise the function is
private to the library. Static linking the test case does not work when
test-coverage is enabled, therefore disable statically linked test cases
in when test-coverage is enabled and give control to the user to disable
statically linked test cases in other cases as well.
