This new attribute would allow to distinguish commands provided
by libraries from commands registered by the application itself,
so vty_dump_element() would print proper description for the
library specific attributes.
All VTY commands defined by the libraries need to use the new API:
- install_lib_element(), and
- install_lib_element_ve,
instead of the old functions (respectively):
- install_element(), and
- install_element_ve().

The SGSN will always bind to 0.0.0.0 in difference the PCU bind is depending
on the info indication. Allow to the user to define a default bind
address.

Both flags are required to allow the NS user to sent BVC RESET for persistent NSE.
On persistent NSE with persistent NS alive configuration (no RESET/UNBLOCK/BLOCK) the
PCU can't detect if the SGSN has restartet or crashed.

A use_count struct gets properly initialized once the first use count is added.
Normally, this happens directly at object allocation. Still make sure
osmo_use_count_to_str_*() don't crash on a yet unused struct use_count.

The NM_ATT_OSMO_NS_LINK_CFG is used for NSVC configuration of osmocom based BTS to support
IPv6 NSVCs.

By adding this functionality, the write_cb() handler can "un-dequeue"
the msgb in case of some error. The msgb might have been modified
meanwhile, e.g. due to a partial write already pulling some data off
the head of the msgb.

The write_queue.c implemetation predates the msgb_*queue_count()
functions for maintaining a count alongside witha msgb queue. Let's
migrate over to those implementations.

Given that commands with either/both of the following attributes:
- CMD_ATTR_DEPRECATED,
- CMD_ATTR_HIDDEN,
never end up in the XML reference, only CMD_ATTR_IMMEDIATE would
be reflected for commands taking effect immediately as follows:
<command id='foo'>
<!-- Global attributes -->
<attributes scope='global'>
<attribute doc='This command applies immediately' />
</attributes>
<!-- Application specific attributes -->
<attributes scope='application'>
<!-- ... -->
</attributes>
<params>
<!-- ... -->
</params>
</command>

gprs_ns2_nsvc_by_sockaddr_nsei is doing the lookup within a NSE.
gprs_ns2_nsvc_by_sockaddr_bind is doing the lookup within a bind.
Make both function look similiar and take similiar arguments.

There shouldn't be any knowledge of the upper layer in the NS layer.
The PCU / SGSN / gbproxy have to add the pointer when parsing the primitives.

utils.h is needed for struct value_string
This probably never caused a problem because every file including
gsm_08_16.h also included utils.h, but we should still include the file
here.

So far there is only osmo_use_count_name_buf(). Also provide a use count to
string using a talloc context, allowing to use OTC_SELECT.
- instead of foo_name(), rather use foo_to_str().
- osmo_use_count_name_buf() returns the buf and not the chars_needed. So add
osmo_use_count_to_str_buf() with a signature that is usable by
OSMO_NAME_C_IMPL().
- provide osmo_use_count_to_str_c() using OSMO_NAME_C_IMPL().

I was reading through the code and noticed many functions not
documented yet, or with incomplete documentation. Change that.

Originally we only learned about the protocol from looking at hexdumps
without any specification or the like.
Due to a GPL request to ip.acecss, we actually do have an 'official'
resource: The packet-ipa.c from their wireshark-1.0.6ipa27.tar.gz
Let's use its contents to complete our definitions here.

According to 3GPP TS 48.008, section 3.2.2.44, the Chosen Encryption
Algorithm IE, which may be included in the following messages:
- 3.2.1.2 ASSIGNMENT COMPLETE
- 3.2.1.8 HANDOVER REQUEST
- 3.2.1.10 HANDOVER REQUEST ACKNOWLEDGE
- 3.2.1.12 HANDOVER COMPLETE
- 3.2.1.25 HANDOVER PERFORMED
- 3.2.1.31 CIPHER MODE COMPLETE
is coded as follows:
0000 0001 No encryption used
0000 0010 GSM A5/1
0000 0011 GSM A5/2
0000 0100 GSM A5/3
0000 0101 GSM A5/4
0000 0110 GSM A5/5
0000 0111 GSM A5/6
0000 1000 GSM A5/7
basically A5/X => X + 1. All other values are Reserved for future
international use. As can be seen, value 0x00 is RFU. Passing
this value to some encoding functions would result in a PDU with
this IE omitted. Although, some functions would still encode
Chosen Encryption Algorithm IE with this RFU value.
Let's ensure that all functions behave consistently.
