Using the RSL_CHAN_* constants, we sometimes need to add 1 to the chan bits
to indicate e.g. the second TCH/H channel.
RSL_CHAN_NR_1 marks this lowest channel bit that needs to be added.
The name is analogous to RSL_CHAN_NR_MASK.

The definitions in this header file (and associated strings in the
c file) are generic about the GPRS Layer3 signalling protocols, and
thus should be part of the library.

This can be used with get_value_string() to improve debugging output.

Various users of gsm48_hdr apply the same hardcoded shifts/bitmasks to obtain
the transaction ID encoded in the upper nibble of the protocol discriminator.
Centralize. Patch for openbsc.git will follow.

Add inline functions for both release <= 98 and release >= 99 as well as a
default define. Use the release 98 by default since the current code base uses
the r98 bitmasks.
These inline functions relieve callers of the decision on masking bits of the
protocol discriminator and message type octets.
Also add a define for the protocol discriminator extension to one octet length
(GSM48_PDISC_EXTEND).
Apply new pdisc function in gsm0480.c.
[hfreyther: Make the hdr param const]

These patches enhance the Supplementary Service (SS) processing from
only being able to handle USSD to other SS, specifically activation,
deactivation and interrogation of those SS. Registration is not yet
implemented.
include/osmocom/gsm/protocol/gsm_09_02.h has been added with needed
values for SS.
Modified by Harald Welte to keep the old ussd-only functiosn for API/ABI
stability.

This adds support for A-over-IP and LCLS related message/IEI
definitions.
Old definitions are in decimal, which is very hard (at least for me)
to compare with the binary tables in the spec. Hex is much easier
to manually compare for completeness/correctness. I didn't touch
the existing definitions, but think they should move to hex, too.

Rename NM_ATT_O_REDUCEPOWER to NM_ATT_OSMO_REDUCEPOWER, which
makes it more clear that this is an osmcoom specific attribute.
Also, we cannot simply overload 0x01 as an already defined OML
attribute. The problem is quite simple: When we use abis_nm_att_tlvdef
during the TLV parse, 0x01 will match to NM_ATT_ABIS_CHANNEL,
which is defined as { TLV_TYPE_FIXED, 3 }.
So instead, we need to introduce a new abis_nm_osmo_att_tlvdef[],
which has to be patched into abis_nm_att_tlvdef[] by the means of
tlv_def_patch(), exactly how we do it for bs-11 and nanobts specific
attributes.
I'm using 0xfe for the attribute, as 0xfe doesn't overlap with the IPA
specific attribues (and we might want to combine/merge the 12.21 plus
IPA plus osmocom spefici attributes)

This information element has been added to the MM Information
message in GSM24.008. This patch adds it to the tlv_definition
to keep the TLV parser from breaking.

There is no real reason to keep the include directory a multi-level
recursion, so instead declare everything within include (so that we
can use proper nobase_ declarations) and be it.
Please note that since we removed the sub-Makefile.am, ./configure
will not create the directory structure for us on out-of-tree builds,
so we have to make sure the directory we're generating to exists first.
