* Separate stdout and stderr buffers:
vdc's return codes get sent to stdout, but the possible presence of
other error messages in the output buffer will cause a valid return
from vdc not to be parsed properly, and subsequent decryption to fail
due to "misunderstood" return code.
eg on the U11+ (htc_ocm) libc will generate an error to stderr due to
a missing property area resulting a proper connection to vold being
incorrectly parsed, and breaking decryption.
* Improve logging.
