The function hash_show is now only called by hash_command, so mark it as static (and drop from hash.h). We only call hash_command when any of CONFIG_CMD_CRC32, CONFIG_CMD_SHA1SUM or CONFIG_CMD_HASH are set. Since hash.c is linked in unconditionally we must take extra care with functions that bring in read-only strings as these will not be discarded.
