Some hashing commands permit saving the hash in an environment variable,
and verifying a hash from there. But the crc32 command does not support
this. In order to permit crc32 to use the generic hashing infrastructure,
add a flag to select which behaviour to use.

Add a parameter that allows you to store the SHA1 sum to either a
memory location or a variable.

Loosely based on CONFIG_CRC32_VERIFY.
The sum to verify against can be in memory, in a variable, or the last
parameter to the function directly.

Change all files in common/ to use CMD_RET_USAGE instead of calling
cmd_usage() directly. I'm not completely sure about this patch since
the code since impact is small (100 byte or so on ARM) and it might
need splitting into smaller patches. But for now here it is.

* Fix: if using sha1 command watchdog timed out
* change function call sha1_csum(..) to the watchdog-safe variant
sha1_csum_wd(..) to support watchdog reset

There's no real need to keep these functions in the cmd_mem file since
they do not use any of the common global mem variables. So split them
out into their own dedicated cmd files.
