RPL: prevent unintended memory access (rpl_remove_header)
...
When it goes to the default label in the switch statement of
rpl_remove_header(), UIP_EXT_BUF does not always point to an IPv6 extension
header. "Move to next header" process should be done only in case of
UIP_PROTO_DESTO. Otherwise, it returns with doing nothing.

RPL non-storing: fix a bug causing an infinite loop
...
It falls into an infinite loop if it goes to the default label in the switch
statement of rpl_srh_get_next_hop() or rpl_process_srh_header().

rpl-ext-header: Use 8-octet unit for HBHO length
...
According to RFC 2460 the length field of the Hop-by-Hop options header
should use a 8-octet unit (multiple of 8 byte).
In a normal configuration the RPL_HOP_BY_HOP_LEN define is 8, so the
current implementation works, but if RPL_HOP_BY_HOP_LEN is a multiple
of 8 the length is not calculated correctly.
