cbfa9eecf4 lossless: fix crash on user abort

475d87d767 WebPEncode: clear stats at the start of encode 
also relocate user_data from WebPAuxStats to the WebPPicture struct to
make clearing easier while placing it closer to the progress hook with
which it's used.
prior to this change some spurious lossless data could be reported in
the lossy (sans alpha) encoding case. additionally user_data could be
lost during lossless encoding.

7d853d79dc add stats for lossless 
* Extend AuxStats with new fields
  it's slightly ABI-incompatible, but i guess it's ok for 0.1.99+
  I expect to add more stats later, possibly (predictor stats, etc.)
* Have cwebp report the features used by lossless
  compression (either for alpha or full lossless coding)
* Print the PSNR for alpha (useful in case of -alpha_q)
* clean-up alpha.c signatures
+ misc cleanup (added const '* const ptr', etc.)

Don't expect a visible speed diff. it's just cool.
(and, that's one less TODO in the code).

should actually be an assert().
