Use symbolic names rather than magic numbers. Remove unneeded extra
pointer in send_seg().

  mesh: replace MESH internal defines by shared ones

Replace BT_AD_MESH_* by MESH_AD_TYPE_*.

Both sets of definition have been added almost at the time, so maybe
it was a 'race condition'.

  mesh: net: constify tx path

Although the first byte of network packets has the same value for all 4
'send' functions, it feels much more natural to assign this byte at the
location(s) where the packet is assembled, rather than where it is sent.
This improves the readability because send_msg_pkt() isn't called with a
partially uninitialized buffer anymore.

  mesh: net: remove unused stuff

'struct mesh_key_set' and 'struct net_decode' arent't used anymore since
commit 994932b740c7 ("mesh: Refactor friend.c and net.c for central key
DB").

'mesh_status_func_t' isn't used anymore since commit c4bf0626fb62
("mesh: Replace storage_save_config with mesh_config_save_config").

  mesh: crypto: mesh_crypto_aes_ccm_encrypt(): remove unused parameter

The 'out_mic' pointer isn't written by this function and all callers
pass a NULL pointer for this. It's obviously not required (and would not
work), so lets remove it.

  mesh: crypto: simplify mesh_crypto_packet_parse()

- NULL pointer checks are not required (no caller passes NULL pointers)
- reuse result of mesh_crypto_network_header_parse() rather than
  determining value of 'CTL' again.

  mesh: fix corrupted relay packets

Currently, all relayed packets are broken!

At the point when net_key_encrypt() is called from net_rx() for
encrypting a relay packet, the packet size must include the NetMIC
field. But the length of this field has already been removed during
decryption of the incoming packet (by decrypt_net_pkt()), although
mesh_crypto_packet_decrypt() has correctly reset the NetMIC field to
zeroes.

Move stripping of the NetMIC field length from decrypt_net_pkt() to
mesh_crypto_packet_parse(), so that the field length is only stripped
from the payload message (but keeping the field length for the network
PDU). Additionally add extra length checks during parsing.
