3582dedd4e gnrc_sixlowpan_iphc: check ptr != NULL in compressible check
Not only does this leave open a risk to crash the node for the check
in `_compressible()` but also is the `tmp` check below getting confused
when `ptr` is `NULL`, since `gnrc_pktbuf_start_write()` returns `NULL`
in that case.

43c2c728c9 gnrc_sixlowpan_iphc: fix _compressible()
When either `gnrc_sixlowpan_iphc_nhc` or `gnrc_udp` is not compiled
in `_compressible()` never returns `true`. This causes the
`dispatch` snip in `gnrc_sixlowpan_iphc_send()` to be of length 0,
meaning `dispatch->data` is `NULL`, causing possible crashes when
trying to send IPv6 packets over 6LoWPAN without NHC or UDP.

69d9ecc0d9 gnrc_sixlowpan_iphc: refactor reception for #8511
This refactors reception/decoding part of `gnrc_sixlowpan_iphc` to the
more layered approach modeled in #8511. Since the reception part is
already complicated enough I decided to divide send and receive up into
separate changes.

faa47a0e03 gnrc_sixlowpan_iphc: Fixed encoding when COMP=0
Summary:

Even ehen COMP is cleared, the algorithm always elides part of the address when a matching
context is found.

This behviour occurs because in the line

  if ((src_ctx != NULL) || ipv6_addr_is_link_local(&(ipv6_hdr->src)))

the COMP bit is not tested.

This patch fixes the problem by setting [src|dst]_ctx to NULL if the
context must not be used.
