[PATCH v3 bluetooth-next 0/8] 6lowpan: udp compression/uncompression fix

[Alexander Aring <alex.aring@gmail.com>]

The current 6LoWPAN udp compression/uncompression is completely broken.
This patch series fix a lot of udp compression/uncompression issues and
add support parsing with lowpan_fetch_skb/lowpan_push_hc_data functions.

I tested it in all cases of compressions in wireshark and a contiki
sensornode.

Changes since v3:
 - add patch to introduce lowpan_push_hc_data helper function.
 - remove patch to fix nullpointer dereferencing and replace it with
   a patch which use the lowpan_push_hc_data function in compress_udp_header
   function. This fixes the nullpointer dereferencing problem also and is more
   readable.
 - add missing newline in pr_debug_ratelimited.

Changes since v2:
 - remove unnecessary casts and brackes, suggested by Werner Almesberger.
 - use pr_debug_ratelimited instead of pr_debug on patch 4/7.
