# In the following test, each condition is a check and logical
# comparison (or or and) that sets the rc value. Every check is run so
# the last check in the series to fail will be the rc that is
# returned.
#
# If a check fails we error before invoking the hash functions because
# hash functions may successfully take the hash of a directory on BSDs
# (UFS filesystem?) which is not what the rest of the ansible code
# expects
#
# If all of the available hashing methods fail we fail with an rc of
# 0. This logic is added to the end of the cmd at the bottom of this
# function.
# Return codes:
# checksum: success!
# 0: Unknown error
# 1: Remote file does not exist
# 2: No read permissions on the file
# 3: File is a directory
# 4: No python interpreter
# Quoting gets complex here. We're writing a python string that's
# used by a variety of shells on the remote host to invoke a python
# "one-liner".
