Ports maintrainer mode?

[Alexey Golodov]

Looking through the ports, I see that sometimes maintrainers include in
Makefile block with actions for maintrain port.
There are different ways to define it (starting with MAINTRAINER_MODE in
devel/git, and ends if user = $maintrainer_username)
Probably, this feature should be unify and added to ports system?
