Christopher Faulet eb89e4f3e0 BUG/MEDIUM: spoe: Return an invalid frame on recv if size is too small
Frames with a too small size must be detected on receive and an error must
be triggered. It is especially important for frames of size 0. Otherwise,
because the frame length is used as return value, the frame is ignored (0 is
the return value to state the frame must be ignored). It is an issue because
in this case, outgoing data, the 4 bytes representing the frame size, are
never consumed. If the agent also closes the connection, this leads to a
wakeup loop because outgoing data are stuck and a shutdown is pending.

In addition, all pending outgoing data are systematcially skipped when the
applet is in SPOE_APPCTX_ST_END state.

The patch should fix the issue #2490. It must be backported to all stable
versions.
