This is primarily to get better test coverage over devices with very large erase/prog/read sizes. The unfortunate state of the tests is that most of them rely on a specific block device size, so that ENOSPC and ECORRUPT errors occur in specific situations. This should be improved in the future, but at least for now we can open up some of the simpler tests to run on these different configurations. Also added testing over both 0x00 and 0xff erase values in emubd. Also added a number of small file tests that expose issues prevalent on NAND devices.
