DEV 20200428

Sfanalysis：通过注入自定义动态库，推测并向外部传递渲染开始、渲染提交滞后、渲染结束事件
Sfanalysis：增加自适应动态刷新率、自适应vsync信号滞后间隔
Sfanalysis：在SELinux的权限范围内，向外部传递信号，因此不需要关闭SELinux才能使用
Sfanalysis：在一加7Pro(Android 10)、坚果Pro2(Android 8.1)、Nexus9(Android 7.1)测试通过
uperf：增加Sfanalysis，响应从surfaceflinger传递来的渲染事件
uperf：增加HintSflag，在收到渲染提交滞后之后，在观察到掉帧之前，拉升到最大性能保持0.015秒
uperf：借助Sfanalysis的渲染结束事件，hint提前结束延时从0.2s降低到0.06s
uperf：限制进入sfLag次数限制，每超过400ms间隔可用次数+1，最大到15次
uperf：修复当之前的最低频高于后来的最高频时，设置会无效
uperf：增加DelayedWork，改善定时器资源利用
uperf：尝试修复AffinityHelper死循环
uperf：uxaffinity类型knob交给affinity helper去重
uperf：进入standby后休眠PmMonitor线程
uperf：重构inotifier，改进逻辑一致性
状态转移：备份进入overlay类型hint之前的base类型hint
配置文件生成器：sfLag动作如果是3集群例如sdm855，负载大多数时候在中核，因此中核需要更高的频率
配置文件生成器：高通EAS的费电模式提供更多性能
配置文件生成器：上调一点Exynos 9820中核频率
安装脚本：细分解析msm8916，修复sdm615平台始终安装失败
Makefile：迁移到ndkbuild，编译后二进制大小67k->51k，或许能改进兼容性问题
