Bitmapset has a complex set of APIs, defined in bitmapset.h, and it can be hard to test edge cases with the backend core code only. This test module is aimed at closing the gap, and implements a set of SQL functions that act as wrappers of the low-level C functions of the same names. These functions rely on text as data type for the input and the output as Bitmapset as a node has support for these. An extra function, named test_random_operations(), can be used to stress bitmaps with random member values and a defined number of operations potentially useful for other purposes than only tests. The coverage increases from 85.2% to 93.4%. It should be possible to cover more code paths, but at least it's a beginning.
