- manual reformatting:
  - try to shorten lines
  - keep blocks somewhat aligned
  - remove documentation comments
- make IBC flag bool
- add some braces
- add line breaks into longer functions
- move even longer functions into .cpp file
- move static variables and functions to the end

- move VPS and related classes into VideoParameterSet.h/cpp
- move SPS and related classes into SequenceParameterSet.h/cpp
- move PPS and related classes into PictureParameterSet.h/cpp
- rename ProfileLevelTier.h/cpp to ProfileTierLevel.h/cpp and move ProfileTierLevel class there

No other changes except for minor formatting/comment cleanup

Having a single element reduces the number of data structures that
need to be maintained.

Avoid duplicating variables and functions for each reference list

Changes include:
- use [[maybe_unused]] instead of cast to (void)
- use generic lambda function and remove related comment about C++11
- update MSVC version check
- don't condition '#pragma once' on MSVC version

Virtual boundaries can be set in the encoder config without enabling GDR. The change makes sure, GDR constraints are conditioned on GDR being enabled.

Should also fix memory allocation issues with PicHeader.

Get GeneralHrdParams from VPS or SPS depending on where it is present

Call pop_front() to prevent infinite loop

Avoid having a separate PTL count since we already have a size
for the vector containing the PTLs.

Add a size check to avoid writing into inexistant PTL. This may
avoid bug reports such as #1587
