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

Improve tokenizing of "do{ ... } while(0)".
...
The simplification will be the same for every combination, except for the 'continue' and the 'break'. In that case, keep the block braces.

Fixed ticket #3229 (Segfault with goto):
...
Don't handle labels, gotos, returns and indentations inside the round braces. This is applied not only for simplifyGoto, but also to simplifyFlowControl.
Rewrite enum badly handled by astyle inside mathlib.cpp and move simplifyFlowControl at the end of the simplifyTokenList in order to catch more dead code, not related to the ticket.
