Related to refactoring in !1512, after which ID vectors can only be set with the correct number of IDs.

- converts static arrays to vectors for subpicture related parameters
- improved encoder parameter checking
- mode automatic calculation of subpicture ID length at encoder
- update theoretical limit of maximum number of subpictures

- initialize slice map from subpicture map
- encoder support for inferring slice map from subpicture map
- improve software manual

fixes for layerId setting in the scaled reference pictures, setting of PPS id, and RPL construction with ILRP

fix building error

further clean up

further fix

correct hrd param class,fix OlsHrdParams

first version of HRD.(VPS does not include the ols dementional), need to add another OLS demention)

   - Some LTRP may not be marked in checkThatAllRefPicsAreAvailable( ) after Fix for Ticket 891, so adding LTRP marking to applyReferencePictureListBasedMarking( ) as well.
   - Fix for LTRP delta POC MSB when there are STRP between two LTRP.

* align with spec
* align encoder/decoder
* fix header to trace DCI instead of DPS

Change the checking for missing pictures to check only active reference picture, not all pictures in the RPS
