Add nand_fileio_* helper APIs.
This patch provides helpers APIs that will eliminate duplicated code in the the NAND 'dump' and 'write' commands by factoring their common code into static helper functions. These helpers may be useful for creating new commands, as shown in the final patch to 'verify' flash from a file. Several previously unreported error conditions now generate messages and propogate the return codes, such as when the file fails to open and bad arguments are given. These changes will fix a possible memory leak in nand dump command, in the case that the dump file failed to open. Overall, the changes should be functionally equivalent, but the resulting code will be easier to improve and extend consistently.
