Release Notes for Cppcheck 2.17

New checks:
- staticFunction: detect functions that should have internal linkage since they
  are not used outside of their translation unit (C code only).
- Check null pointer return from memory/resource allocation functions (nullPointerOutOfMemory,
  nullPointerArithmeticOutOfMemory, nullPointerOutOfResources, ctunullpointerOutOfMemory,
  ctunullpointerOutOfResources).

Changed interface:
- Added `reduced` check level. It can be activated with `--check-level=reduced`. You get faster analysis
  but some fewer results. The motivation is to be able to make analysis time "acceptable" for direct usage.
- Added `--report-type` option. Enables printing of guidelines and classifications for several coding
  standards in place of the regular error identifiers and severities.

Other:
- Removed deperecated support for builds via qmake.
- Using a handwritten rule texts file for MISRA C addon violates license and copyright terms. See the
  manual for instructions how to download a official rule texts file from MISRA.
