Subject: Added support for roaring bitmap v3 (#2355)

* Integrated RoaringBitmap v3

* Renamed ndpi_bitmap64 ro ndpi_bitmap64_fuse

* Fixes to ndpi_bitmap for new roaring library

* Fixes for bitmap serialization

* Fixed format

* Warning fix

* Conversion fix

* Warning fix

* Added check for roaring v3 support

* Updated file name

* Updated path

* Uses clang-9 (instead of clang-7) for builds

* Fixed fuzz_ds_bitmap64_fuse

* Fixes nDPI printf handling

* Disabled printf

* Yet another printf fix

* Cleaup

* Fx for compiling on older platforms

* Fixes for old compilers

* Initialization changes

* Added compiler check

* Fixes for old compilers

* Inline function is not static inline

* Added missing include
