batman-adv: Split batadv_priv in sub-structures for features

  The structure batadv_priv grows everytime a new feature is introduced. It gets
hard to find the parts of the struct that belongs to a specific feature. This
becomes even harder by the fact that not every feature uses a prefix in the
member name.

The variables for bridge loop avoidence, gateway handling, translation table
and visualization server are moved into separate structs that are included in
the bat_priv main struct.

This is a 1:1 resent of the RFC. Maybe I will enhance this idea later.

Hello Sven,

some inline comments about the TT part.

I'd prefer:

atomic_t local_entry_num;

uint16_t local_crc

int16_t last_changeset_len;

ops, typo :) I meant "/* protects last_changeset */" (thanks Marek :))
