This handling is not mondatory, but it's better to do so, because
there are card reader with pinpad and token with ack button, which
support user interaction.
User interaction status should be reset at open time. The status
should be reset when the session is closed/stopped. In practice,
since cleanup routine in a driver may not be called properly, it's
good to submit SET_INTERFACE at open time.

comply to the promised interface. Thus the code has been factored out
to a helper function and N has been bumped up correctly and checked in
all cases.
For some uses this changes the behaviour in the error case (i.e. CR or
LF passed): It will now always be C-escaped and not passed to
libassuan which would truncate the line at the first LF.

Actually, when the incorrect expected response length (i.e. Le

byte (i.e. ... 6101) so an additional command has to be sent to the
card to retrieve the last byte. Using the correct length avoids to
send the additional command to retrieve the missing byte, when the
computed length is wrong.
Note that an value of 65537 for E is pretty standard and thus we can
avoid the 6101 return code inmost cases.
