In preparation of the libctrl move to libosmocore[*], I had to move some IPA related functionality from libosmo-abis to libosmocore. This is required as libctrl needs IPA functions, but we cannot make a cyclic library (build) dependency between libosmocore and libosmo-abis.

I took the decision to rename some of the sysmbols for consistency. This is always ugly and creates fall-out, so there never is a good time for it. I thought now it makes sense as things are undergoing modifications anyway.

I was able to do 'make check / make distcheck' of libosmocore / libosmo-abis / osmo-pcu / osmo-bts and openbsc master branches with the recent commits.

If I missed something, please let me know by private mail and I'm happy o clean up further.

Regards, Harald

[*] required to add a control interface to osmo-bts, which is required for things like managing/triggering clock recalibration on sysmobts from external programs.
