Optimize handling of --append=<file> option (execution time, memory)
...
Whitespace was removed from the append data for every configuration
and every file: n(configuration) * n(files).
Removing whitespace immediately after the append data was read can
significantly reduce the execution time and memory usage.
It also allows further improvement because copies to the temporary
object appendCode are no longer needed.

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

Move "information" errors to "style" errors.
...
"information" severity is documented in lib/errorlogger.h as:
Checking information.
Information message about the checking (process) itself. These
messages inform about header files not found etc issues that are
not errors in the code but something user needs to know.
It IS NOT for errors in the code. All the current "information"-
severity errors fit nicely into description of the "style"-
severity.
We definitely need to separate processing information and actual
errors in the code. It is highly confusing for users to mix these
two different things. Hence all current "information" code error
messages are moved to "style" category.
