IDWT 5x3 single-pass lifting and SSE2/AVX2 implementation

Even Rouault fd0dc535ad IDWT 5x3: generalize SSE2 version for AVX2 
Thanks to our macros that abstract SSE use, the functions can use
AVX2 when available (at compile time)

This brings an extra 23% speed improvement on bench_dwt in 64bit builds
with AVX2 compared to SSE2.

Even Rouault fa55b52d19 Improve performance of inverse DWT 5x3 (#953) 
* Use single-pass lifting inverse wavelet transform.
* For vertical pass, use SSE2 when available so as to process 8 columns
  in parallel. This is the most beneficial improvement, since the
  vertical pass involves a lot of cache trashing.

With the bench_dwt utility with default arguments (16383x16383 image),
time goes from 4.064 s to 1.212 s.

Even Rouault 8df2521a60 Remove OPJ_NOSANITIZE in opj_bio_read() and opj_bio_write() (#761) 
Commit 29313eb5 introduced those flags to avoid issues with
-fsanitize=unsigned-integer-overflow
However it is better just to rewrite the loop to avoid such condition
to occur.

Even Rouault 2609fb8077 Packet header writing: set empty packet header bit to 0 when appropriate (small optimization) 2017-06-12 18:38:11 +02:00
Even Rouault 73d1510d47 Encoder: fix packet writing of empty sub-bands (#891, #892) 
There are situations where, given a tile size, at a resolution level,
there are sub-bands with x0==x1 or y0==y1, that consequently don't have any
valid codeblocks, but the other sub-bands may be non-empty.
Given that we recycle the memory from one tile to another one, those
ghost codeblocks might be non-0 and thus candidate for packet inclusion.

Even Rouault 81c5311758 T1: fix BYPASS/LAZY, TERMALL/RESTART and PTERM/ERTERM encoding modes. (#674) 
There were a number of defects regarding when and how the termination of
passes had to done and the computation of their rate.

Even Rouault 9a9b06911e opj_t1_dec_sigpass_raw/opj_t1_dec_refpass_raw: harmonize style with mqc methods 2017-06-02 19:22:15 +02:00
Even Rouault 532243f1fd MQC/RAW decoder: use an artificial 0xFF 0xFF terminating marker. 
This saves comparing the current pointer with the end of buffer pointer.
This results at least in tiny speed improvement for raw decoding, and
smaller code size for MQC as well.

This kills the remains of the raw.h/.c files that were only used for
decoding. Encoding using the mqc structure already.
