949902fd1b const correctness. celt_mode_create() now makes a copy of the static mode 
(if STATIC_MODES is defined) instead of attempting to modify read-only
storage.

3e08a88389 Only the (rising) overlap part of the window is stored now. No need to hold the 
zeros and ones (nor even the second half).

81b38c2295 Moved mdct state and window to the mode so it can be shared between multiple 
encoders and decoders.

4c6bc884c8 "make check" now actually tried to encode and decode to see if things work 
(need to have test files installed otherwise it'll just pass by default)
