(I think the term "template" is fine and accurate, i assume no vty edits these)

In general, the tdefs API was made modular with flexible re-use in mind.
I havent gone into the smallest details of reading this -- I might find a simplification here or there but in general, I think that this is the way to go: plug tdefs API functions to a custom vty "frontend", tailored to per-BTS timers, which is not provided by the tdefs API in itself.

Patchset:
PS12:
Hmm, the task this patch has is actually quite difficult, for these reasons:
- the osmo_tdefs API was implemented with T1234 and X1234 in mind, but not N1234. Looks like we won't get around adding another namespace for N, in the libosmocore tdef API itself. Mainly because T3101 and N3101 collide. (If it's only this one maybe we want an ugly workaround instead? T23101 is N3101?).
Adding the 'N' category is a separate discussion, Vadim and I discussed it a bit in PM and let's say there's potential for diverse opinions.
- the osmo_tdefs API was implemented with a single global timer config in mind, not individual per-object timers. The tdefs API is modular enough to be helpful in implementing this, so no problem here, just many choices to be made.
- confusion: we already have a global timer 'net' / 'T3101'; now we are also adding a per-BTS T3101 as well as N3101. So per-BTS for GPRS, but only global T for CS. And these seemingly identical T3101 items do not interact...? ("are you sure they are separate?" / "did you really use the correct T3101?"...)
I'll not dive into per-line comments now, but I'd like to already say that we need to still work on this patch (and it's not arehbein's fault)

IMO, we should at least log a `NOTICE` message here saying that the T200 values from the BSC and ignored and not applied. Also, a comment in code explaining why we ignore these values would be very welcome. Thanks!
