Modify shared.test to do case independent comparison of filenames. To account for the fact that "c:/test.db" and "C:/test.db" are the same file. (CVS 4780) (check-in: 63915b54cf user: danielk1977 tags: trunk)

Do not release registers used to hold the results of a compound select after just the first select has run. Ticket #2927. For now, we will never release the registers used to hold the result set, since the same register set will be used for each select. This is not an unacceptable register leak and it is the safest approach. (CVS 4778) (check-in: e9fcb79399 user: drh tags: trunk)
