Bug: libEasyGBSDevice.so (armeabi-v7a) 在32位设备上推流崩溃

BuildId: 97b07fb085c40034a6f11b47e8619a9f1f516cf6

崩溃信息:
Fatal signal 11 (SIGSEGV), fault addr 0x14

崩溃堆栈:
__GB28181DeviceCALLBACK+316 → CallStaticVoidMethod+30

原因分析:
__GB28181DeviceCALLBACK 中使用的 jclass 值为 0x14，
这是一个 JNI local reference，只在创建线程内有效。
sua_media_send_thread 是新创建的 native 线程，
该线程中 0x14 不是有效的引用。

修复建议:
在 JNI_OnLoad 或 create() 中通过 FindClass 获取 jclass 后，
使用 NewGlobalRef() 转为 global reference 再缓存。

复现条件:

• 32位设备（armeabi-v7a），arm64-v8a 版本无此问题
• eventType=6 (START_AUDIO_VIDEO) 回调时触发
