Instead of using IP bufs for sending stuff, allocate
a separate buffer that is only used in dtls sub-system
to send the encrypted buffer. This way there is no
possibility to deadlock in the dtls write callback
if we run out of buffers.

etc.

This patch fixes a potential issue in which the signed return value
from the network driver send routine is returned from a caller that
has an unsigned return type. The meaning of a negative return value
from the network driver send routine is that an error occurred. A
return value of 1 means that the packet was sent successfully. A
return value of 0 means that the packet could not be sent. Thus, this
patch converts negative return values from the network driver send
routine to a return value of 0 from the caller.

If the stack is sending network packets by itself, like when
sending router or neighbor solicitation messages, then remember
the original length of the message. This is important because
uIP stack will clear the length of the sent message after it
is sent.
After this change, the lower level drivers can use
the net_buf_datalen() to get the original length of the
buffer. The issue is seen because uIP stack is running in
different fiber than the network device driver.
