3f2227f04c Fix pppos after changing PBUF_POOL to PBUF_RAM 
This partly reverts 31bc2f9b which broke pppos tx as 'pppos_output_append'
implements a custom scheme of checking available pbuf size.
Added a comment why PBUF_POOL is ok for tx in this special case.
See bug #51908

10ae311a93 lowpan6: Rework to speed up dequeue datagram process 
Current implementation iterates the lowpan6_data.reass_list every time
dequeue_datagram() is called.
We can get previous lrh in all the context calling dequeue_datagram().
By adding a prev arguemnt to dequeue_datagram(), we can speed up the
dequeue datagram process.

All the callers never check return value of dequeue_datagram() as it
always return ERR_OR, thus make it return void instead.

8d8572354b lowpan6: fix bug #47291 (wrong datagram size for fragmentation) 
Fragment datagram_size and datagram_offset should be calculated from the uncompressed datagram.
We did this on the compressed size and thus were not compatible to other implementations.
Now my test setup communicates with contiki sicslowpan.

546a8c4860 Revert "vj_compress_tcp: help coverity to see we're not accessing out of bounds (this is a union)" 
This reverts commit 2390eb68266fbe5bf76cab36cf1e357a6d51aabb.
I've already marked other issues like this as 'invalid', so do this here, too.
Although I don't like the code, there's not much use in fixing this in one place only.
