T1: fix BYPASS/LAZY, TERMALL/RESTART and PTERM/ERTERM encoding modes (#674)

[rouault]

There were a number of defects regarding when and how the termination of
passes had to done and the computation of their rate.

Note: the build of the pull request from rouault/fix_bypass_pterm_termall at https://travis-ci.org/uclouvain/openjpeg/builds/241107896 failed since it identifies the branch as 'master' and thus pulls the 'master' branch of the openjpeg-data repository, instead of the updated 'fix_bypass_pterm_termall' branch from the uclouvain repo. I've thus pushed the branch into the uclouvain repo and build of this branch succeeds: https://travis-ci.org/uclouvain/openjpeg/builds/241109714 + https://ci.appveyor.com/project/detonin/openjpeg/build/2.1.1.612

Note 2: uclouvain/openjpeg-data@be376b3 modifies the expected result of the following test step : "opj_compress -i @INPUT_NR_PATH@/Bretagne2.ppm -o @TEMP_PATH@/Bretagne2_3.j2k -EPH -M 38". Indeed -M 38 corresponds to 32 (SEGSYM) + 4 (TERMALL) + 2 (RESET), and TERMALL was broken.

Now he md5sum of the raw images after encoding + decoding is the same (except for Bretagne2_4 which use a lossy parameter -r 800), including for the new tests that test most combinations of encoding flags.
