libosmocore/libosmo-abis changes + fallout

[Harald Welte]

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.
