this add new API for sound compress to support gapless playback. As noted in Documentation change, we add API to send metadata of encoder and padding delay to DSP. Also add API for indicating EOF and switching to subsequent track
Also bump the compress API version

v3:
- Change back to ioctl struct with padding
But this makes difficult to know which parameter is unavailable in this kernel, as already mentioned in the thread. You need to add another ioctl or add a mask in the struct. Or, take back to single key/value pairs, so user can see the -ENOENT or such error for non-existing parameters.
Right, but we have the API version. Wouldnt it be okay to use API version to find what kernel supports, of course it doesnt scale well as many more params are added.
