f_send_l3() replaces f_send_l3_gmm_llc() to have one function
which sends L3 messages for Iu and Gb at the same time.
This allows to share most of the tests between Iu & Gb.

Make the decoding level (BSSGP, LLC, SNDCP, L3) configurable, so the
existing PCU tests, that expect messages only decoded to the BSSGP
level, can pass again. Move the SNDCP decoding in f_dec_bssgp above the
L3 decoding, so f_dec_bssgp goes through the layers in the reverse order
of f_send_bssgp_dec.
I have verified, that all testsuites using the BSSGP Emulation (SGSN,
PCU, PCU-SNS) are still working with this patch.

It originally seemed like a great idea to define a custom record
which aggregates the decoded BSSGP, LLC, L3 and/or SNDCP and passes
it to the individual ConnHdlr. However, particularly with testcase
interoperability for IuPS in mind, this seems bogus. Also, we
never really took advantage of this.
Let's now decode as far as we can decode any PDU, and then send the
decoded version of that PDU via the ports between the BSSGP_Emulation
and the ConnHdlr component.

The gb_index was forgotten to given to the new function f_send_l3().

to work, but the TC_attach_rau_a_b is the only testcase which uses #0
