Add macros for whitelisting coverity violations. These macros use pragma directives. The pragma directives and whitelisting macros are only enabled when a coverity scan is being run. The whitelisting macros have been added to a new header called static_analysis.h. The contents of safe_ops.h (CERT C safe ops) have been moved into static_analysis.h because this will be the new header for static analysis related macros/defines/etc. JIRA NVGPU-3820 Change-Id: I9c63f20f670880b420415535738034619314b7c3 Signed-off-by: Adeel Raza <araza@nvidia.com> Reviewed-on: https://git-master.nvidia.com/r/2180600 Reviewed-by: mobile promotions <svcmobile_promotions@nvidia.com> Tested-by: mobile promotions <svcmobile_promotions@nvidia.com>
