When the bond list is full, drop the oldest disconnected device instead
of the oldest NVS entry, and allow a per-bond except flag so selected
devices are never auto-removed.

- Add sdp_seq to avoid p_ccb being free during sdp
- Changed some BTA_Pba functions to return non-void value
- Improve error catching and report
- Refactor bta_pba_client_response to avoid UAF problem
- Rearrange btc_pba_client init flag to avoid some disturbing bug
Add smp_repairing_is_allowed() behind BT_BLE_SMP_HARDENED_REPAIRING so a
peer cannot replace an existing bond with one that has less MITM
protection, no Secure Connections, or a shorter key. Compare a preceding
Security Request against the pairing command AuthReq, not the
association-model result, and always allow first pairing.
A refusal keeps the stored bond. Pairing-failure erase is split by link
role: default is erase as Central and keep as Peripheral.
Closes BLERP (NDSS 2026) V3, V4 and V6.

Cancel any active SDP search during disabling and mark the BTA SDP
callbacks inactive so late search completions are not propagated
after deinit. Guard BTC side SDP completion handling after cleanup
to avoid null references.
AVDT:
- Roll back CCB allocation when cmd/rsp queue creation fails
- Free media packet on invalid handle in AVDT_WriteReqOpt
- Zero-init timeout failure message before GETCAP callback
- Initialize lcid_tbl to 0xFF to avoid mapping to tc_tbl[0]
BTA/AVRCP:
- Use size_t for AVRC message copy buffer allocation
- Allocate before register in BTA_AvEnable
- Guard BTA_AvRegister callback when enable never completed
- Remove invalid free of inline Cover Art image_descriptor
A2DP BTC/API:
- Default g_a2dp_on_deinit to true before profile init
- Reject source audio send when A2DP is deiniting
- Add shutdown state check in btc_a2dp_sink_shutdown
- Guard A2DP source timer against freed dynamic local param
- advance connect queue on synchronous connect_cb failure
- lock bta_alarm_hash_map in all BTA timer APIs
- free controller params after stack disable; cleanup on init fail
- handle BTE_InitStack failure and signal init future
- validate HCI remote name event length before parse

- Return bt_status_t from btc_hf_ag_audio_data_send to avoid silent buffer leak on SLC failure
- Break SCO CI data loop when SCO is not open to prevent CPU starvation
- Guard BTM_FreeSCN(0) and reset SCN after free in bta_ag_del_records
- Use OI_UINT32 for mSBC decode frame length to avoid stack corruption
- Bound AT Dial command string copy to BTA_AG_AT_MAX_LEN
HFP Client:
- Check osi_calloc result before use when reassembling split mSBC frames
- Use OI_UINT32 for mSBC decode frame length to avoid stack corruption
- Free SDP db, collision/AT timers and queued AT cmds before scb reset on disable
- Fix mSBC EV3 second-packet payload length calculation (same as AG)
- Reject pcm_resample input smaller than overlap window (96 bytes) on filtered path
