bitvec_unhex() is the only consumer in libosmocore for bitvec_write_field() so far

I've tested that approach as well but it makes code much harder to read without
providing any real benefits.

Yes, the only potentially problematic functions are bitvec_*_field()

Will do.

The functions for that are part of another patch currently under review as well. I
did not wanted to reimplement them just for one test-case. I can extend this once
it's merged.

Yes. In the patch in question I instead return write_index+len to make it easier for
caller.

cheers,
