Previously we didn't take into account puncturing and BER was always around
30% for GPRS/EDGE bursts because of they use puncturing coding unlike
"classical" GSM bursts.

Our implementation generates ERROR CTRL messages with ID=error when it
is unable to parse a CMD. However, it doesn't account for them when
trying to receive and parse this kind of message. As a result, it will
return an ERROR message with a different description. This commit fixes
the old behaviour to success at parsing and returning the received
description to the caller.

enum gsm0808_permitted_speech does not have any value strings. Lets
add value strings to make debugging easier.

The value string table gsm48_chan_mode_names[] lacks a function

vty_test: add test against ambiguous cmd causing use-after-free and memory
leaks. Add this test along with the fix, because the new test triggers the
memory use-after-free and leaks, causing build failures.
Add cmd_deopt_with_ctx() to allow passing a specific talloc ctx.
is_cmd_ambiguous(): keep all cmd_deopt() allocations until the function exits.
Add a comment explaining why. Before this, if a command matched an optional
"[arg]" with square brackets, we would keep it in local var 'matched', but we
would free the string it points to at the end of that loop iteration; upon
encountering another match, we would attempt to strcmp against the freed
'matched'. Instead of adding hard-to-read and -verify free/alloc dances to keep
the 'matched' accurately freed/non-freed/..., just keep all cmd_deopt() string
allocated until done.
Needless to say that this should have been implemented on a lower level upon
inventing optional args, but at least this is fixing a program crash.

The conv_gen.py utility was tested against both Python 2 and 3,
so there is no need to enforce Python 2. Also, having:
#!/usr/local/bin/python{2|3}
is a bad idea, because Python may be installed in a different location.

In Change-Id I5a70eb65952cbc329bf96eacb428b07a9da32433 we redirected
all OSMO_ASSERT() via osmo_panic(). However, this caused various
applications to have build failures, as OSMO_ASSERT() now appeared
to be able to return to the call site. Let's inform the compiler
explicitly that there's no return from osmo_panic().
Change-Id: I8adf4c7b0ee6a4581cef8dd4e9f6a1dfde70ee55
A loooong time ago, we introduced osmo_panic() as a wrapper around
abort(). The advantage is, that this wrapper can be overridden, and
that it will also work in embedded (bare iron) targets, where the
abort simply translates to an infinite loop.

The return code from bssgp_tlv_parse() was not checked for a parsing
error. In case of a parsing error the stored return code could have
been overwritten later in this function.

In Change-Id I1cee271fed0284a134ffed103c0d4bebbcfde2a8 we added support
for a new session state IE, but we didn't add any value_string array
for string conversion of it. Let's fix this.

This function can be used to resolve the error message type for
a given message type. Can be used by generic error handlers that

This function can be used when there is only a part of GSM 04.80
message available - Facility IE, e.g. when a message is carried
over GSUP/MAP. Let's expose it.
Refactoring includes the following:
- adding the 'gsm0480_' prefix;
- correcting inverted return value;
- cosmetic code style changes.
Change-Id: I623c39ffbe6cdee65eade8435a2faa04d0da193e
In some cases, there is no need to parse the whole message,
e.g. during the conversion from DTAP to GSUP/MAP. This
function can be used to extract given IE from a message.

This function permits the user to register deprecated log categories,
which will ensure that if log categories are removed from a program,
old config files will still load.
We simply dynamically allocate a cmd_element and install it at
CFG_LOG_NODE. Not registering it at VIEW_NODE or ENABLE_NODE
ensures that it's not accessible from the interactive VTY, but only
from the config file / configure node.

The general idea about each osmo_fsm_instance having a separate
log-level was to be able to selectively increase/show/enable logging
for some FSM instances (e.g. of a particular subscriber) while
maintaining normal logging verbosity for all other instances of the
same FSM.
The introduction of LOGPFSML() in Change-Id
If295fdabb3f31a0fd9490d1e0df57794c75ae547 broke that idea, as it would
use a compile-time log level, irrespective of the
osmo_fsm_inst.log_level setting of the given instance.
Let's combine the two:
Use the explicit level stated at LOGPFSML(), _unless_ this instance
has a higher log_level configured.
This way, all FSMs should normally be created with
osmo_fsm_inst.log_level == LOGL_DEBUG. At that point LOGPFSM()
statements would be rendered at debug level, typically below the
threshold of most logging configurations.
Code that has explicit higher log levels like LOGPFSML(fi, LOGL_ERROR)
would always be printed, as it is an error message.
And if we now increase the osmo_fsm_inst.log_level, then even the normal
LOGPFSM() statements would suddenly be logged at that higher level,
selectively increasing log verbosity - like originally intended.

In order to be able to transfer SS/USSD messages via GSUP,
this change introduces the following new message types:
- OSMO_GSUP_MSGT_PROC_SS_*,
and the following new IE:
- OSMO_GSUP_SS_INFO_IE
which represents an ASN.1 encoded MAP payload coming to/from
the mobile station 'as is', without any transcoding.

Unlike TCAP/MAP, GSUP is just a transport layer without the
dialogue/context. This prevents us from having session based
communication, required e.g. for USSD. But we can emulate
TCAP dialogue by adding additional IEs, which would allow
to relate each message to a particular session.
This change introduces the following IEs:
- OSMO_GSUP_SESSION_ID_IE,
- OSMO_GSUP_SESSION_STATE_IE,
which optionally can be used to indicate that the message is
related to a session with given ID, and to manage session
state, i.e. initiate, continue, and finish.
