4adad5a19a wavpackenc: reset trailer info on block encoding
In some cases, in particular if several blocks are needed because of
the channel layout (e.g. 2.1), the information used to write the
trailing bits terminating the sample data was not reset.

This would cause potential desync on the decoder, although decoded
samples were actually mostly fine.

Fixes ticket #3879.

e32eddaa51 wavpackenc: make assert more thorough
It was only validating that normal data wasn't filling the buffer.
However, extra data may be written afterwards.

ddad093972 wavpackenc: fix number of samples per block
Currently, the encoder will try to reduce it down to 150000, but the
decoder will complain starting at 131072 (WV_MAX_SAMPLES). Therefore,
change the loop limit.

Fixes ticket #3881.

4a5cc34b46 wavpackenc: assert on too small buffer
bytestream2_* will not cause buffer overflow, but in that case, this means
the allocation would be incorrect and the encoded result invalid. Therefore,
assert no overflow occurred.

2ba58bec20 wavpackenc: proper buffer allocation
The allocation didn't account for headers, that can be easily 79 bytes.
As a result, buffers allocated for a few samples (e.g. 5 in the original
bug) could be undersized.

Fixed ticket #2881.
