1. Move mpp_log.h to inc for external user.
2. Add mpp_debug.h for mpp internal logging.
3. Fix some warning.
4. Add log level setup function.
5. Check env log_level value in mpp_get_log_level call.
NOTE:
1. mpp internal module should use mpp_debug.h and mpp external user
should use mpp_log.h
2. Use mpp_get_log_level to update mpp_log_level when the env changed.

When /dev/mpp_service is opened and be forked to another thread the
leaked fd will increase file refcnt in kernel.
Then the codec kernel session will be leaked on mpp_destroy.

Batch mode will send multiple task to kernel at one time. And its
non-block poll is triggered by timer and looper.
This mode will reduce the ioctl overhead on ultra multi-instance case.
Main features and some notes:
1. Each client type has independence batch server.
2. Each mpp_device can attach or not attach to server independently.
3. When a device is attached to server all its tasks will be sent to
kernel through the server session not original client session.
4. The tasks are sent non-block and wait in block or non-block.
5. The batch mode can only be switch on/off when hardware is not
working.
