The current implementation of consuming output from interactive shells
relies on being able to find an expected prompt somewhere within the
output buffer after sending the command. This is useful in situations
where the prompt does not appear in the output itself, but in some
practical cases (such as the starting of an XML-RPC server for scapy)
the prompt exists in one of the commands sent to the shell and this can
cause the command to exit early and creates a race condition between the
server starting and the first command being sent to the server.
This patch addresses this problem by searching for a line that strictly
ends with the provided prompt, rather than one that simply contains it,
so that the detection that a command is finished is more consistent. It
also adds a catch to detect when a command times out before finding the
prompt or the underlying SSH session dies so that the exception can be
wrapped into a more explicit one and be more consistent with the
non-interactive shells.
