* [B.A.T.M.A.N.] [PATCH 1/3] batman-adv: convert multiple /proc files to use sysfs

To: b.a.t.m.a.n; +Cc: Marek Lindner
This is the first patch in a series of patches which aim to convert
all batman-adv /proc files to sysfs. To keep the changes in a
digestable size it has been split up into smaller chunks. During
the transition period batman-adv will use /proc as well as sysfs.
As a first step the following files have been converted:
aggregate_ogm, bonding, originators, transtable_global, transtable_local

batman-adv is in the process of migrating to sysfs, hence batctl needs
to adapt the file paths. In addition batctl makes use of the input
validation support of the new files in sysfs.
