- add option to completely disable
- add iparameter to software manual

Use vectors and resize them if needed instead of deleting and
reallocating memory for every picture. This appears to have a
significant impact on decoder run time.

Use PLTRunMode type where appropriate instead of bool since
using vector<bool> creates a number of issues

fix some JCCR related indentation, encapsulation, and descriptive text, add --PYUV to software manual

- refactoring of MatrixIntraPrediction.h/.cpp (merged classes MatrixIntraPrediction and PredictorMIP, removed namespace Mip)
- removed unused variable posBias in function computeReducedPred
- fixed list size in function reduceHadCandList

This reverts commit 9503ca9c

- fixed build error

- Fix for the case that uninitialized or invalid best cost values are referred during search candidate selection

This reverts commit 9503ca9c

Add a cfg option "FastIntraPass", and use it for turning on/off the fast algorithm of intra pass coding in RDO. In cfg files, the parameter FastIntraPass is set as 0 for RA and 1 for LDB/LDP.

initial commit of JVET_O0119_BASE_PALETTE_444: palette in HEVC and palette mode coding in JVET-N0258

It cleans up old ISP code that is no longer used anymore. The code was used to allow only one ISP split depending on the block size. However, this functionality is not needed anymore after the adoption of JVET-N0308 during the Geneva Meeting in March, which limited the usage of ISP to CUs with a maximum size of 64x64 samples. This clean-up eliminates various unnecessary checks and improves the readability of the code.
