  To: b.a.t.m.a.n

main.h includes statements which (re)define preprocessor variables which
influence the compiled code. This makes it necessary to include it in all
files. For example, it redefines pr_fmt used to the module as prefix for
each pr_* message.

It is easier to detect if a include is already there for a used
functionality when the includes are ordered. Using an alphabetic order
together with the grouping in commit 7df620092727 ("batman-adv: Add
required includes to all files") makes includes better manageable.

From: Markus Pargmann <mpa@pengutronix.de>

The tvlv functionality in main.c is mostly unrelated to the rest of the
content. It still takes up a large portion of this source file (~45%, 588
lines). Moving it to a separate file makes it better visible as a main
component of the batman-adv implementation and hides it less in the other
helper functions in main.c

  To: b.a.t.m.a.n

The bat_algo functionality in main.c is mostly unrelated to the rest of the
content. It still takes up a large portion of this source file (~15%, 103
lines). Moving it to a separate file makes it better visible as a main
component of the batman-adv implementation and hides it less in the other
helper functions in main.c.

There are several places in batman-adv which provide logging related
functions. These should be grouped together in the log.* files to make them
easier to find.

  To: b.a.t.m.a.n

The bat_algo.h had some functions declared which were not part of the
bat_algo.c file. These are instead stored in bat_v.c and bat_iv_ogm.c. The
declaration should therefore be also in bat_v.h and bat_iv_ogm,h to make
them easier to find.

There are several places in batman-adv which provide logging related
functions. These should be grouped together in the log.* files to make them
easier to find.
