RANAP: Split FormatInformationParameter / SDUParameterItem
...
The definition of the above data types as per 3GPP specs results in a
SEQUENCE_OF() an anonymous structure, which is slightly inconvenient to
use. So let's split the SEQUENCE OF part and the actual definition of
the item in separate types.

Enable vty command to output talloc report

I don't think I can print this into a string and thus output it via VTY.
In that case it might be smarte to do in a signal handler

hnbgw: Use the now-compiling RANAP encoder+decoder code
...
So far, we copy-pasted/cherry-picked individual encoder/decoder
functions as the overall ranap_{encode,decode} didn't compile yet.
As the latter is now finally compiling, we can remove those copies and
link in ranap_{encode,decode}.o

One further RANAP hacking session
...
This is not development, it is random trial and error hacking. I really
hate the fact that we have no useful asn.1 code generator and need to
work with hacks like asn1tostruct.py and asn1c without information
object classes :/
This commit is a one-day-long iteration of trial+error, manually editing
and adding the .asn source of RANAP until we get something that in the
end at least compiles and links. Do I trust the resulting code? No.
But we have no alternative :(

asn1tostruct: Avoid erroneous double-underscores

We shouldn't generate names like

stripped before converting all '-' to '_'.

didn't support that. But loosing the ability to regenerate the C source
is not an option either.
