This leaves a handful of warnings about using '@sa @ref async_safety'.
Clang thinks that the '@sa' command has an empty paragraph in this
case, but it appears to be a false positive and a bug in Clang.
Issue: PLCR-543
- Added @internal flags to exclude private types from the doxygen
output.
- Added a few documentation groups for internal modules that were
missing documentation grouping.
With this change, only two callbacks are required, and the symbol lookup
can be performed only once per method. Each callback is required to skip
updating the found symbol information if its match is not better (ie,
has a higher address) than previous matches.
