g_test_rand_int provides a reproducible random integer number, using a
different number seed every time but allowing reproduction using the
--seed command line option. It is thus better suited to tests than
g_random_int or random.

All current bitmap_set test cases set range across word, while the
handle of a range within one word is different from that.
Add case to set 1 bit as a represent for set range within one word.

Add a test for bitmap_set. There are three cases:
* Both start and end is BITS_PER_LONG aligned
* Only start is BITS_PER_LONG aligned
* Only end is BITS_PER_LONG aligned

These helpers copy the source bitmap to destination bitmap with a
shift either on the src or dst bitmap.
Meanwhile, we never have bitmap tests but we should.
This patch also introduces the initial test cases for utils/bitmap.c
but it only tests the newly introduced functions.

Bitmap test used sizeof(unsigned long) instead of BITS_PER_LONG.
