re-structure the OpenBSC directory layout

The new structure divides the code into a number of libraries
for the BSC core functionality, MSC core functionality, Abis transport,
TRAU and other bits.

This doesn't introduce any functional code change but simply moves
around files and alters Makefile.am accordingly.

Next step would be to disentangle a lot of the inter-library
dependencies and make the individual bits of code more independent.

/*
* This code derived from a leaked document from the GSM standards.
* Some missing pieces were filled in by reverse-engineering a working SIM.
* We have verified that this is the correct COMP128 algorithm.
*
* The first page of the document identifies it as
* _Technical Information: GSM System Security Study_.
* 10-1617-01, 10th June 1988.
* The bottom of the title page is marked
* Racal Research Ltd.
* Worton Drive, Worton Grange Industrial Estate,
* Reading, Berks. RG2 0SB, England.
* Telephone: Reading (0734) 868601 Telex: 847152
* The relevant bits are in Part I, Section 20 (pages 66--67). Enjoy!
*
* Note: There are three typos in the spec (discovered by
* reverse-engineering).
* First, "z = (2 * x[n] + x[n]) mod 2^(9-j)" should clearly read
* "z = (2 * x[m] + x[n]) mod 2^(9-j)".
* Second, the "k" loop in the "Form bits from bytes" section is severely
* botched: the k index should run only from 0 to 3, and clearly the range
* on "the (8-k)th bit of byte j" is also off (should be 0..7, not 1..8,
* to be consistent with the subsequent section).
* Third, SRES is taken from the first 8 nibbles of x[], not the last 8 as
* claimed in the document. (And the document doesn't specify how Kc is
* derived, but that was also easily discovered with reverse engineering.)
* All of these typos have been corrected in the following code.
