tcap loadshare: move last_asp_idx_sent from cfg to runtime struct

The last_asp_idx_sent is a runtime information and not configurable.
Move it to the other runtime state.

tcap loadshare: allow to define the fallback mechanism for unroutable TCAP messages

When a TCAP Continue/End/Abort message is received, but no TCAP session entry can be found
and no valid TCAP range is available for the dtid, the message can be either:

- rejected by returning an error with udts
- routed by round robin to all available ASP of this AS

To define the behaviour, a new vty option is introduced:
```
   tcap-unroutable-sessions (reject-udts | load-share-over-as)
```
Defaults to reject-udts.

osmo_interact: improve vty transcript language by a regular rexex

Currently the transcript language understand 3 different tokens:
... (ignore all lines until the following line matches)
... !REGEX (ignore all lines except REXEX)

But to support osmo-stp with different compile options, the
vty help is indented with different amount of spaces depending on the compile options.
To support those add a regular regex using the prefix !r!

E.g.
```
OsmoSTP(config-cs7-as)# ?
-  description       Save human-readable description of the object
vs
+  description               Save human-readable description of the object
```

To use the new regex, the line would be:
```
!r!  description[ ]+Save human-readable description of the object
```

Further all regex special characters needs to be escaped.
```
  description   Save human-readable description of the object (for humans)

!r!  description[ ]+Save human-readable description of the object \(for humans\)
```

osmo_interact: improve vty transcript language by a regular rexex

Currently the transcript language understand 3 different tokens:
... (ignore all lines until the following line matches)
... !REGEX (ignore all lines except REXEX)

But to support osmo-stp with different compile options, the
vty help is indented with different amount of spaces depending on the compile options.
To support those add a regular regex using the prefix !r!

E.g.
OsmoSTP(config-cs7-as)# ?
-  description       Save human-readable description of the object
vs
+  description               Save human-readable description of the object

TCAP loadshare: Rework initial selection of a node

The original TCAP loadshare plan was to used the OTID of a TCAP Begin to select

However this should not be used anymore. Instead the correct one would be to
do a load-sharing across all available ASP and keep this relation ("sticky" sessions).

The counter SS7_AS_CTR_TCAP_ASP_FALLBACK will be re-used by a later patch.

TCAP loadshare: allow to define the fallback mechanism for unroutable TCAP messages

When a TCAP Continue/End/Abort message is received, but no TCAP session entry can be found
and no valid TCAP range is available for the dtid, the message can be either:

- rejected by returning an error with UTDS
- routed by round robin to all available ASP of this AS

To define the behaviour, a new vty option is introduced:
```
   tcap-unroutable-sessions (reject-utds | load-share-over-as)
```
Defaults to reject-utds.

TCAP loadshare: Rework initial selection of a node

The original TCAP loadshare plan was to used the OTID of a TCAP Begin to select
the node.
However this should not be used anymore. Instead the correct one would be to
do a load-sharing across all available ASP and keep this relation ("sticky" sessions).

The counter SS7_AS_CTR_TCAP_ASP_FALLBACK will be re-used by a later patch.

Fix unhandled (un)mapping events

If a mapping event (create slotmap) and an unmapping event (delete
slotmap) exists at the same time, none of these events were handled.
These mappings stayed in 'NEW' state. Subsequent mappings of different
slots were then ignored.

This issue has been reproduced and is fixed with this patch.

vty: update help string for nokia_site model

Original Nokia BTS support in OsmoBSC was limited to MetroSite,
UltraSite and InSite, aka the Site family.  After the recent series
of fixes, the same code also supports Flexi Multiradio (actively
used in the present) and will most likely also work on Flexi EDGE
(intermediate between UltraSite and Flexi MR), although that model
is currently untested.

BTS model name "nokia_site" is thus outdated and inaccurate now.
It has been decided (see https://gerrit.osmocom.org/c/osmo-bsc/+/42729)
to keep this model name unchanged for now, given the uncertainty
of how Nokia BTS support will evolve in the future if and when
we implement support for IP Abis on Flexi family, potentially
followed by future support for subsequent IP-only models.

In the meantime, change vty help string to reflect current support
for both Site and Flexi families with the same model selection.

nokia: rename BTS model from nokia_site to nokia-e1

When Nokia BTS support was introduced into Osmocom in 2011, only
{Metro,Ultra,In}Site family was supported, and the name of this
BTS model in OsmoBSC was set to nokia_site.  However, we now
also support Flexi Multiradio in E1 Abis configuration with the
same code, automatically applying Site-specific or Flexi-MR-
specific handling based on the type code returned by the BTS
itself - hence calling the BTS model nokia_site and referring
strictly to *Site in docs and vty help is now misleading.

At the same time, these newer BTS models support both E1 and IP
Abis options, and there is a desire to support IP Abis operation
at some point in the future.  When/if Nokia IP support becomes a
reality, we will certainly need to know upfront which type of Abis
we are working with, similarly to how we currently distinguish
upfront between E1 and IPA types of BTS.  Therefore, the new BTS
model name is set to nokia-e1, rather than just "nokia", with the
expectation that we will also have nokia-ip in the future.

bts_nokia_site.c source file name is deliberately left unchanged.
Source file renames make it difficult to follow changes, hence a
slightly outdated source file name is deemed to be a lesser evil.

nokia: rename BTS model from nokia_site to nokia-e1

When Nokia BTS support was introduced into Osmocom in 2011, only
{Metro,Ultra,In}Site family was supported, and the name of this
BTS model in OsmoBSC was set to nokia_site.  However, we now
also support Flexi Multiradio in E1 Abis configuration with the
same code, automatically applying Site-specific or Flexi-MR-
specific handling based on the type code returned by the BTS
itself - hence calling the BTS model nokia_site and referring
strictly to *Site in docs and vty help is now misleading.

At the same time, these newer BTS models support both E1 and IP
Abis options, and there is a desire to support IP Abis operation
at some point in the future.  When/if Nokia IP support becomes a
reality, we will certainly need to know upfront which type of Abis
we are working with, similarly to how we currently distinguish
upfront between E1 and IPA types of BTS.  Therefore, the new BTS
model name is set to nokia-e1, rather than just "nokia", with the
expectation that we will also have nokia-ip in the future.

bts_nokia_site.c source file name is deliberately left unchanged.
Source file renames make it difficult to follow changes, hence a
slightly outdated source file name is deemed to be a lesser evil.
This source file may also be split in the future as Nokia BTS
support code grows.

gsm_set_bts_type(): fix switch statement

The switch statement on (bts->type) in this function exhibited
two defects:

1) From the beginning, each unhandled BTS type was listed explicitly,
   instead of providing a default case;

2) When Nokia-specific initialization was added in 2015,

   and GSM_BTS_TYPE_UNKNOWN cases, besides the intended case

transceiver: add optional Laurent burst LUT modulation (int16)

Introduce an optional Burst LUT optimization for Laurent-based burst
modulation, enabled via --with-burst-lut.

- Add precomputed Laurent LUT tables (float and int16 I/Q variants)
- Generate LUT at initialization (prepareBurstLUT)
- Use LUT-based modulation for sps=4 when enabled
- Add configure.ac option and USE_BURST_LUT define

This reduces runtime computation by replacing per-burst Laurent
processing with memcpy-based LUT lookups.

backends reusing the same scheduling logic

Change-Id: I7ce61bee4ca7ca50ef190982f1a0e4ce57c8c838

trx: factor out FN timer processing into common helper

Extract core FN timer handling logic into trx_fn_timer_process()
to decouple it from timerfd-specific code.

This allows reusing the same scheduling logic for alternative
timer backends (e.g. WebSDR) while keeping timerfd integration
as a thin wrapper.

No functional changes intended.

trx: add JSON stats export for WebSDR API

Introduce stats_json.c providing JSON serialization for:
- stats and counters
- rate counters
- BTS state
- TRX/transceiver state
- WebSDR runtime metrics

Add osmobts_get_stats() API to expose these via WebSDR
interface and export it in Emscripten build

This enables programmatic access to data previously available
via VTY (e.g. "show stats", "show bts")

trx, bts: add optional WebSDR backend (callback-based transport)

Introduce WebSDR backend enabled via ENABLE_WEBSDR,
adding an alternative callback-based transport alongside
existing socket-based TRX/OSMUX I/O

Implement:
- TRX control via osmotrxlib_process_command()
- TRXD data via apitrx_tx_call()/trx_data_read()
- clock handling via apibts_clock_ind() and external timers
- Osmux integration via ws_osmux_* helpers

Adapt scheduler to support API-based burst submission and
external timer callbacks in WebSDR mode

Disable signal handling, stats and socket I/O when building
with ENABLE_WEBSDR

Add WebSDR API entrypoint, Emscripten build target and
example configuration

Enables running BTS/TRX stack in WebAssembly environments

trx: handle synchronous TRX control callbacks in provision FSM

Set *_sent flags before issuing TRX control commands to ensure
correct state when responses are delivered synchronously
(e.g. WebUSB callback path)

Also guard FSM state handling in st_open_poweroff() to avoid
duplicate transitions if state was already changed by a
synchronous response
