osmo-bts-trx: shut down on stale clock indication from transceiver

We expect the transceiver to be a reliable, monotonic clock source.
If it reports an FN far behind our local timer (elapsed_fn < 0) while
far more wall-clock time elapsed than its FN advance accounts for,
its clock has likely stalled and the indication carries a stale frame
number.  Acting on it drags the scheduler backwards and re-transmits
already-sent TDMA frames, corrupting lchan-internal state(s).

Detect this and shut down the process, same rationale as the existing
"PC clock skew too high" check in trx_fn_timer_cb().

osmo-bts-trx: reset BTS GSM time on clock (re)start

trx_sched_clock_started() is called when the transceiver is powered
on, e.g. after an A-bis link re-establishment, which in ttcn3-bts-test
happens once per testcase.  The transceiver restarts its TDMA frame
number from ~0, but we only reset the per-TRX clock state (tcs),
leaving bts->gsm_time.fn at the previous epoch's value.

As a result the first (low) FN reported by the transceiver is mistaken
for a huge backwards jump, e.g.:

  l1sap.c:628 Invalid condition detected: Frame difference is 102-10386=2705364 > 1!

Reset bts->gsm_time to FN 0 here so each clock epoch starts clean.

server: do not abort process on short conn message

conn_read_cb() used OSMO_ASSERT() to check that the received
message holds at least a full osmo_pcap_data header.  Although
conn_segmentation_cb2() should only ever hand up complete frames,
asserting on a length derived from network input means a framing
anomaly would abort the entire server (taking down all other clients'
captures).  Close the offending connection gracefully instead,
consistent with the other error paths in this function.

tls: do not treat GNUTLS_E_AGAIN/INTERRUPTED as fatal on read

osmo_tls_client_bfd_cb() treated any non-positive return from
gnutls_record_recv() as a fatal error and tore down the session.  On a
non-blocking socket gnutls_record_recv() can return GNUTLS_E_AGAIN or
GNUTLS_E_INTERRUPTED (both negative but non-fatal), which would drop
an otherwise healthy TLS session.  Handle them as retryable, mirroring
the existing logic in tls_write().

tls: fix broken certificate hostname verification

verify_cert_cb() retrieved the gnutls session pointer and passed it to
gnutls_certificate_verify_peers3() as the expected hostname.  But the
session pointer is set to the osmo_tls_session struct (it is needed by
cert_callback()), not a hostname string.  Hostname matching was
therefore performed against raw struct bytes, rendering verification
meaningless and potentially reading out of bounds, even when
"tls verify-cert" was enabled.

Store the configured hostname in struct osmo_tls_session and have
verify_cert_cb() read it from there.  Also drop the stray
gnutls_certificate_verify_peers3() call in the client setup: it ran
before any handshake (so there were no peer certificates yet) and its
result was ignored; the real verification happens via the registered
callback during the handshake.

server: fix NULL deref of file_hdr_msg when store is disabled

When a connection has storing disabled (no store), conn->file_hdr_msg
is never populated.  The previous link-header handling skipped the
first branch (gated on conn->store) and fell through to the comparison
branch, which dereferenced the still-NULL conn->file_hdr_msg, crashing
the server on the first PKT_LINK_HDR from such a client.

Gate the whole header tracking on conn->store and simply free the
message when not storing, since osmo_pcap_conn_restart_trace() already
no-ops in that case.

client: fix off-by-one in wrapped pcap stats counter

When a libpcap stats counter (ps_recv/ps_drop/ps_ifdrop) wraps around
UINT_MAX, get_psbl_wrapped_ctr() computed the delta as
(UINT_MAX - old_val) + new_val, omitting the single increment that
takes the counter from UINT_MAX through zero.  Add the missing +1 so
the reported delta matches the real number of increments.

client: honor IPv4 header length in GPRS filter

The GPRS-NS/BSSGP filter assumed a fixed 20-byte IPv4 header (IP_LEN)
when locating the UDP header and payload.  When the captured packet
carries IPv4 options (ip_hl > 5), udp_data/payload_data pointed into
the middle of the headers and check_gprs() parsed garbage, classifying
packets incorrectly.

Use the actual header length from ip_hl, reject malformed headers
(ip_hl < 5), and re-validate that the larger headers fit within the
captured length before computing the payload.

tv_sec * 1000 * 1000 was evaluated in int arithmetic.  Where time_t /
tv_sec is 32-bit, this overflows for any tv_sec > ~2147, corrupting
the 64-bit timestamp_usec well before the year 2038.  Cast tv_sec to
uint64_t before the multiplication so the whole expression
is computed in 64 bits.

server: vty: validate rotate-localtime modulus against the new interval

apply_rotate_localtime() computed the maximum allowed modulus from
pcap_server->rotate_localtime.intv, the currently-stored (old) interval,
rather than the intv argument being applied.  On first configuration the
stored interval is the default 0, so the switch hit the default case and
rejected an otherwise valid command; when changing intervals the modulus
was bounds-checked against the wrong interval.  Switch on intv instead.

server: fix msgb leak on duplicate link header

rx_link_hdr() takes ownership of msg on success (rx_link() only frees
it on failure).  Both branches that call update_conn_file_hdr_msg()
free msg, but when an identical link header was already stored neither
branch ran and msg was leaked.

This happens on every duplicate PKT_LINK_HDR, e.g. a client that
periodically resends its header.  Free msg explicitly in that case.

vty: clamp configured snaplen to the wire-framing limit

osmo-pcap carries each captured packet in a frame whose length field
(struct osmo_pcap_data.len) is a uint16_t, so any snaplen above ~64 KiB
cannot be transported and is silently clamped by the server when sizing
its receive buffer (calc_data_max_len() caps at UINT16_MAX). The VTY,
however, advertised libpcap's MAXIMUM_SNAPLEN (262144), misleading users
into configuring values that never take effect.

Introduce OSMO_PCAP_MAX_SNAPLEN (65535) and, in both the client "pcap
snaplen" and server "max-snaplen" handlers, warn and cap the value to it
when a larger one is given. The command syntax keeps the <1-262144>
range for backwards compatibility so existing configs still parse; the
help text now documents the effective 64 KiB limit.

Transceiver52M: fix viterbi-eq soft bits on platforms where char is unsigned

The viterbi-eq demodulator stores soft bits into chars.
"char" is signed on x86/amd64 but unsigned on arm64.
On arm64 the stored byte 0x81 (== -127) is read back as +129, so after the
sign flip and vectorSlicer() clamp every soft bit collapses to 0.0.

The same issue also appears to be present in the MS code path, so it was
(blindly) fixed there as well. The MS fixes are untested!

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: 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 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.
