/* test_bt_dev.c — 蓝牙 DEV 自识别宿主验证（纯逻辑，bt_dev.c）。
|
||
*
|
||
* 覆盖矩阵（对齐任务B 宿主测试要求）：
|
||
* D1 bt_dev_detect_mac：a2dpsrc/<MAC> 端点 → 提取 MAC（含 a2dp_source、多空行、多设备取第一个、
|
||
* 无 a2dpsrc / 空输出 / NULL → -1）。
|
||
* D2 bt_dev_rewrite：真实 alsa.conf 文本 → DEV=、device 两处 MAC 换成目标，保留 codec/其余 token；
|
||
* 同值 → 1（无需改动）；无 pcm.bluealsa / 无 DEV= → -1；带引号风格保留。
|
||
*
|
||
* 编译（在 patch_v2/meow_audiod 下）：
|
||
* cc -Wall -Wextra -o test_bt_dev test_bt_dev.c bt_dev.c
|
||
* 运行：./test_bt_dev
