主干存在该问题，还未解决.

因为对于热插入的sd卡，如果被其中一个线程操作拿住锁资源，

热插拔会导致disk资源状态未修改为UNUSED，造成资源泄露

现在修改为在拔出sd卡时，销毁disk锁资源之前，先将disk状态修改成UNUSED

主干存在该问题，下一步同步主干.

挂载rootfs需要emmc驱动，emmc驱动还没有初始化好，内核就尝试挂载rootfs了，
现修改为通过一个事件同步，emmc驱动完成后写事件，内核读到这个事件再挂载rootfs

Mainly adding missing headers, removing redundant headers that
induce undefined symbols or rearranging existing headers
according to dependencies betheen them.
Also add missing include paths to makefiles and make configs.

Note: direct inclusion of pthread.h in disk.h is caused by the
latter being used almost everywhere, including third_party libraries.
Putting pthread.h there releases us from affecting more code.

Basically fixes build for anything that is not default HiSi
configuration.
