topology: pre-processor: Move the call to expand variables Remove the call to snd_config_expand_custom() to expand the top-level input config. And replace it with calls to snd_config_evaluate_string() for each non-compound config while processing individual objects. This will allow retreving variable definitions from object attribute values and global definitions. Add a new field "current_obj_cfg" to hold the current object config being pre-processed. This will facilitate adding simple math expressions for computing attribute values for objects based on other attributes. For ex: we can set the expression for buffer size as follows: buffer_size "$[($in_channels * 48) * 4]" The buffer_size attribute value will be computed with the attribute value "in_channels" based on the expression above. So if $in_channels = 2, buffer_size will be evaluated to 384. Additionally this change also permits computing attribute values based on previously computed values. For example: buffer_size "$[($in_channels * 48) * 4]" dma_buffer_size "$[$buffer_size * 2]" dma_buffer_size will be computed as 768. Note that the order of definitions for buffer_size and dma_buffer_size matters because the evaluation for dma_buffer_size depends on the evaluation of buffer_size. In order to conform to this, the tplg_object_copy_and_add_param() is modified to add attribute configs from class config to an object using snd_config_before() instead of snd_config_add(). With this change, we no longer need to set the auto_attr_updater for buffer type widget objects. So remove it.

aplay: Fix for arecord recording ghost data When recording we should only write the amount of data read to output file instead of copying whole buffer. This fixes glitches appearing at the end of recorded file, when stopping recording.
