Herman Chen d8ed1f4eb1 [mpi]: Add poll interface to mpi 
1. Add poll with timeout. Support three mode: block/non-block/timeout.
2. Change control MPP_SET_INPUT_BLOCK and MPP_SET_OUTPUT_BLOCK.
3. Remove msleep in most mpp interface.

* NOTE: We can choose decoder's buffer mode here.
* There are three mode that decoder can support:
*
* Mode 1: Pure internal mode
* In the mode user will NOT call MPP_DEC_SET_EXT_BUF_GROUP
* control to decoder. Only call MPP_DEC_SET_INFO_CHANGE_READY
* to let decoder go on. Then decoder will use create buffer
* internally and user need to release each frame they get.
*
* Advantage:
* Easy to use and get a demo quickly
* Disadvantage:
* 1. The buffer from decoder may not be return before
* decoder is close. So memroy leak or crash may happen.
* 2. The decoder memory usage can not be control. Decoder
* is on a free-to-run status and consume all memory it can
* get.
* 3. Difficult to implement zero-copy display path.
*
* Mode 2: Half internal mode
* This is the mode current test code using. User need to
* create MppBufferGroup according to the returned info
* change MppFrame. User can use mpp_buffer_group_limit_config
* function to limit decoder memory usage.
*
* Advantage:
* 1. Easy to use
* 2. User can release MppBufferGroup after decoder is closed.
* So memory can stay longer safely.
* 3. Can limit the memory usage by mpp_buffer_group_limit_config
* Disadvantage:
* 1. The buffer limitation is still not accurate. Memory usage
* is 100% fixed.
* 2. Also difficult to implement zero-copy display path.
*
* Mode 3: Pure external mode
* In this mode use need to create empty MppBufferGroup and
* import memory from external allocator by file handle.
* On Android surfaceflinger will create buffer. Then
* mediaserver get the file handle from surfaceflinger and
* commit to decoder's MppBufferGroup.
*
* Advantage:
* 1. Most efficient way for zero-copy display
* Disadvantage:
* 1. Difficult to learn and use.
* 2. Player work flow may limit this usage.
* 3. May need a external parser to get the correct buffer
* size for the external allocator.
*
* The required buffer size caculation:
* hor_stride * ver_stride * 3 / 2 for pixel data
* hor_stride * ver_stride / 2 for extra info
* Total hor_stride * ver_stride * 2 will be enough.
*
* For H.264/H.265 20+ buffers will be enough.
* For other codec 10 buffers will be enough.
