Fix #3243 (Improve non reentrant function check)
...
- Use std::map instead of linear std::list walk
and run fast tests like tok->isName() first.
Global speed up is 4.8% (profiled with google-perftools)
- Catch function invocations in global namespace
and ignore other namespaces except "std".
std::localtime() and others are also non-thread safe on POSIX.
Note: The check matches f.e. also on "std::getrpcbyname()",
but that would result in a compile error anyway.
No need to have an extra "std::xxxxx" whitelist.
- Remove double listed "rand" and "getrpcbyname" function names
