batman-adv: Add SPDX license identifier above copyright header The "Linux kernel licensing rules" require that each file has a SPDX license identifier as first line (and sometimes as second line). The FSFE REUSE practices [1] would also require the same tags but have no restrictions on the placement in the source file. Using the "Linux kernel licensing rules" is therefore also fulfilling the FSFE REUSE practices requirements at the same time.

batman-adv: Drop publication years from copyright info The batman-adv source code was using the year of publication (to net-next) as "last" year for the copyright statement. The whole source code mentioned in the MAINTAINERS "BATMAN ADVANCED" section was handled as a single entity regarding the publishing year. This avoided having outdated (in sense of year information - not copyright holder) publishing information inside several files. But since the simple "update copyright year" commit (without other changes) in the file was not well received in the upstream kernel, the option to not have a copyright year (for initial and last publication) in the files are chosen instead. More detailed information about the years can still be retrieved from the SCM system.

batman-adv: OGMv2 - add basic infrastructure This is the initial implementation of the new OGM protocol (version 2). It has been designed to work on top of the newly added ELP. In the previous version the OGM protocol was used to both measure link qualities and flood the network with the metric information. In this version the protocol is in charge of the latter task only, leaving the former to ELP. This means being able to decouple the interval used by the neighbor discovery from the OGM broadcasting, which revealed to be costly in dense networks and needed to be relaxed so leading to a less responsive routing protocol.

batman-adv: Include main.h in bat_v_ogm.h 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.

batman-adv: Use includes instead of fwdecls While it can be slightly beneficial for the build performance to use forward declarations instead of includes, the handling of them together with changes in the included headers makes it unnecessary complicated and fragile. Just replace them with actual includes since some parts (hwmon, ..) of the kernel even request avoidance of forward declarations and net/ is mostly not using them in *.c file.
