Fix #178 Avoid referencing encoder parameter in low level MC function

See merge request jvet/VVCSoftware_VTM!290

Fix of the DQP signaling with multiple TUs (Ticket #181)

See merge request !280

When MC for luma only is desired, use existing luma/chroma parameters
instead of encoder-specific field in data structure

Also take care that luma only MC doesn't imply IBC

Fix for Ticket #150

See merge request !284

#179: fix of reshaper implementation (encoder-side RDcost) when lumaDQP is on for HDR

See merge request jvet/VVCSoftware_VTM!269

Fix for Ticket #182

See merge request !289

  - Fix overflow during reconstruction process.

SPS cleanup - removal of deprecated SPSNext parameters

See merge request jvet/VVCSoftware_VTM!279

Fix for tickets #91 and #180

See merge request jvet/VVCSoftware_VTM!275

Fix for ticket #179 Retrieval of QP value to use for chroma

See merge request jvet/VVCSoftware_VTM!271

Deleted the TU retrieval from the DQP code in xCompressCU and the TU pointer being equal to nullptr check.

  - Triangle merge list zero-MV candidates not properly initialized.

Fix of the DQP signaling when there are multiple luma TUs in Single Tree and there is only one TU containing all of the chroma information

avoid dereferencing a nullptr object

MSVC minimum version and clang identification

See merge request jvet/VVCSoftware_VTM!277

Update ALF syntax element with specification

See merge request jvet/VVCSoftware_VTM!278

- fail to build when MSVC version too low
- properly identify clang as compiler

Dereferencing a nullptr should be avoided, even if the passed object is never used.
It may not be the most elegant solution to pass an empty list object, but it should work.

Fix ticket #177 on encoder decoder mismatch for VTM-4.0rc1

See merge request jvet/VVCSoftware_VTM!273

IBC block search history status is not reset for each frame, which may affect IBC searching results for the second frame.

SW and spec mismatch related to wide angle #174

See merge request jvet/VVCSoftware_VTM!260

remove SPSNext extension and sort SPS

See merge request jvet/VVCSoftware_VTM!268

- all elements of SPSNext are moved into SPS
- syntax elements of SPS are sorted according to draft (as far as possible)
- comments were added where software and draft diverge
