Note that on the input side, the 3-digits flag may be left false when the MNC
is >99 anyway. On the decoded side, the flag is set accurately.

Event names are displayed in VTY commands so all FSM should have them.
Print an error message if an FSM is registered without event names.
We could also return an error code, however at present no caller checks
the return value of osmo_fsm_register() so this would be pointless.
Add event names to the test FSM and update expected output accordingly.

For all other decode operations we report the BER, but not for the
RACH. This results in osmo-bts-trx not being able to report BER
to the higher layers, which is possible on other BTS backends.
Let's close this gap by introducing gsm0503_rach_ext_decode_ber()
and gsm0503_rach_decode_ber() with the usual n_errors / n_bits_total
arguments.

It seems with default flags in_buf was being memzeroed by the compiler.
When compiling with -O0, that's not the case anymore and printf prints
after first 16 bytes, printing extra garbage which doesn't match the
expected output.

inline keyword is a hint for the compiler to inline the function, but
it's not mandatory. If no static or extern is specified, the definition
is only visible in the current unit but the identifier still has
external linkage.
When running with -O0 it seems the compiler (gcc 7.2.1) decides to use
the external linkage but at the same time it seems it's not generating
the function symbol. Fix it by explicitly stating that we want to use
static linking for this function.

Instead of forcing test failure via assert on first error encountered,
let it run until completion and print detailed error log. This
simplifies troubleshooting by letting user to see more errors from
single run and more details on each of the errors. Update test output
with explicit test results.

Previously an incorrect length value was passed to both
gsm_7bit_decode_n_ussd() and gsm_7bit_encode_n_ussd()
functions during test_7bit_ussd() execution, due to:
octets_written = strlen(decoded);
The problem is that a 7-bit encoded string takes less memory
than its 8-bit equivalent. So, here strlen() returns one-byte
bigger value, that octets_written is. This then causes the
uninitialized memory access.

When a bad GSM voice frame is received, it's being replaced
by a silence frame. This may cause unpleasant audio effects.
This change implements a functionality to craft a replacement
frame from the last known good frame. Currently, only FR is
supported, support for other codecs may be added latter.

Add gsm48_encode_ra() which takes appropriate struct as [out] parameter
instead of generic buffer. Using uint8_t buffer instead of proper struct
type prooved to be error-prone - see Coverity CID57877, CID57876.
Old gsm48_construct_ra() is made into tiny wrapper around new
function. The test output is adjusted because of the change in function
return value which was constant and hence ignored anyway.

Recent patch I563764af1d28043e909234ebb048239125ce6ecd introduced returning
NULL from rate_ctr_group_alloc() when the index passed already exists.
Instead of returning NULL, find an unused group index and use that, adjust the
error message.
In stats_test.c, adjust, and also assert allocated counter group indexes
everywhere.
Rationale:
The original patch causes osmo-sgsn to crash as soon as the second subscriber
attempts to establish an MM context. Of course osmo-sgsn is wrong to a) fail to
check a NULL return value and crash and b) to fail to allocate an MM context
just because the rate counter group could not be allocated (it still rejects
the MM context completely if rate_ctr_group_alloc() fails).
Nevertheless, the price we pay for rate counter correctness is, at least in
this instance, way too high: osmo-sgsn becomes completely unusable for more
than one subscriber.
Numerous other places exist where rate_ctr_group_alloc() is called with a
constant index number; from a quick grep magic I found these possible breaking
points:
osmo-sgsn/src/gprs/gb_proxy.c:1431: cfg->ctrg = rate_ctr_group_alloc(tall_bsc_ctx, &global_ctrg_desc, 0);
osmo-sgsn/src/gprs/gprs_sgsn.c:139: sgsn->rate_ctrs = rate_ctr_group_alloc(tall_bsc_ctx, &sgsn_ctrg_desc, 0);
osmo-sgsn/src/gprs/gprs_sgsn.c:270: ctx->ctrg = rate_ctr_group_alloc(ctx, &mmctx_ctrg_desc, 0);
osmo-sgsn/src/gprs/gtphub.c:888: b->counters_io = rate_ctr_group_alloc(osmo_gtphub_ctx,
>phub_ctrg_io_desc, 0);
osmo-bsc/src/libfilter/bsc_msg_acc.c:87: lst->stats = rate_ctr_group_alloc(lst, &bsc_cfg_acc_list_desc, 0);
osmo-pcu/src/bts.cpp:228: m_ratectrs = rate_ctr_group_alloc(tall_pcu_ctx, &bts_ctrg_desc, 0);
osmo-pcu/src/tbf.cpp:793: tbf->m_ctrs = rate_ctr_group_alloc(tbf, &tbf_ctrg_desc, 0);
osmo-pcu/src/tbf.cpp:879: tbf->m_ul_egprs_ctrs = rate_ctr_group_alloc(tbf, &tbf_ul_egprs_ctrg_desc, 0);
osmo-pcu/src/tbf.cpp:880: tbf->m_ul_gprs_ctrs = rate_ctr_group_alloc(tbf, &tbf_ul_gprs_ctrg_desc, 0);
osmo-pcu/src/tbf.cpp:970: tbf->m_dl_egprs_ctrs = rate_ctr_group_alloc(tbf, &tbf_dl_egprs_ctrg_desc, 0);
osmo-pcu/src/tbf.cpp:977: tbf->m_dl_gprs_ctrs = rate_ctr_group_alloc(tbf, &tbf_dl_gprs_ctrg_desc, 0);
osmo-pcu/src/tbf.cpp:1475: ul_tbf->m_ctrs = rate_ctr_group_alloc(ul_tbf, &tbf_ctrg_desc, 0);
osmo-pcu/src/bts.cpp:226: m_ratectrs = rate_ctr_group_alloc(tall_pcu_ctx, &bts_ctrg_desc, 1);
We can fix all of these callers and then reconsider returning NULL, but IMO
even into the future, rate counter group indexes are not something worth
failing to provide service for. For future bugs we should keep the automatic
index picking in case of index collisions. We will get an error message barfed
and can fix the issue in our own time, while the application remains completely
usable, and even the rate counters can still be queried (at wrong indexes, but
life is tough).

The recently added ctrl_cmd_parse2() returns non-NULL cmd with error messages
upon parsing errors. In handle_control_read(), use ctrl_cmd_parse2() and send
those back to the CTRL command sender as reply.
Retain the previous "Command parser error" reply only in case ctrl_cmd_parse2()
should return NULL, which shouldn't actually happen at all.

In ctrl_handle_msg() (code recently propagated from handle_control_read()),
talloc_free() the parsed ctrl_cmd in all code paths. In particular, a free was
missing in case ctrl_cmd_handle() returns CTRL_CMD_HANDLED.
CTRL_CMD_HANDLED is triggered by GET_REPLY / SET_REPLY parsing, as show by
ctrl_test.c. With the memleak fixed, adjust expected test output and make a
detected mem leak abort the test immediately.

To report invalid characters in identifiers, it is desirable to escape any
weird characters. Otherwise we might print stray newlines or control characters
in the log output.
ctrl_test.c already uses a print_escaped() function, which will be replaced by
osmo_escape_str() in a subsequent patch.
control_cmd.c will use osmo_escape_str() to log invalid identifiers.

Some Abis/RSL messages such as "Release Indication" contained 3 extra
bytes from an L3 Information header which should not be there according
to specs in GSM 08.58 (section 8.3 "Radio link layer management
messages"). Other RSL messages were affected by the same issue, except
for "Establish Indication", which had already a workaround in
send_rslms_dlsap.
This commit fixes the issue in a generic way, removes the "Establish
Indication" and fixes the test accounting for the bug, as it otherwise
fails after applying the changes.

All successful and all error code paths of bssgp_fc_in() free the msgb, except
the code path calling fc_enqueue() when the msg is dropped (due to queue being
full, or failure to allocate).
Callers could theoretically catch the -ENOSPC return value and discard the
msgb. However, in other code paths, a callback's return value is returned,
which is expected to free the msgb, so such callback would have to never return
-ENOSPC when it freed the msgb. Much simpler semantics would be to free the
msgb in every code path, no matter which kind of error occurred.
Who is currently calling bssgp_fc_in and how do they handle the return value?
- bssgp_fc_test.c ignores the return value (and hits a mem leak aka sanitizer
build failure if the queue is full).
- fc_timer_cb() ignores the return value.
- bssgp_tx_dl_ud() returns the bssgp_fc_in() rc.
- which is returned by a cascade of functions leading up to being returned,
for example, by gprs_llgmm_reset(), which is usually called with ignored
return code.
At this point it is already fairly clear that bssgp_fc_in() should always free
the msgb, since the callers don't seem to distinguish even between error or
success, let alone between -ENOSPC or other errors.
bssgp_fc_test: assert that no msgbs remain unfreed after the tests.
Adjust expected results.

Print remaining msgbs when done, then free the entire tall_msgb_context. To be

that all msgb are allocated in, we would in a final cleanup discard all msgbs,
i.e. we would not verify that all msgb are cleaned up properly.
If we create the msgb context and *don't* clean it up in the end, the sanitizer
build fails because the context root is not cleaned up.
Easiest is to actually allocate all msgb at NULL ctx, because then any msgb
that aren't cleaned up properly would still linger, while we don't leave a root
ctx that we need to clean up either.
Helps fix sanitizer build on debian 9.
