[Qgis-psc] QEP 337: Coverity Scan cleanup

[Nyall Dawson]

Hi all,

The Coverity Scan tool is a highly regarded tool for static analysis
of complex c++ projects. It's able to pro-actively identify many code
issues (such as potential crashes, memory leaks, and other unsafe
behavior) which aren't picked up by other tools (such as clang-tidy or
cppcheck).

Currently, the tool reports around 1075 open issues when run on the
QGIS master codebase.

These issues range from false positives to trivial fixes through to
serious issues which require substantial work to fix. Unfortunately,
the large number of trivial issues currently reported in QGIS make the
tool effectively useless for QGIS, as the critical issues are hidden
amongst the many hundreds of trivial issues.

The newly submitted QEP
https://github.com/qgis/QGIS-Enhancement-Proposals/pull/337 seeks to
cleanup the Coverity Scan results for QGIS, by fixing trivial issues
and closing false positives.

See the QEP PR at
https://github.com/qgis/QGIS-Enhancement-Proposals/pull/337 for
further details and discussion.

(This project will be submitted as a candidate for the 2025 grant funding)
