Thomas Jarosch 55d9f0873a 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

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.

Kimmo Varis 3cfe7ca1a7 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.

Ticket: #3165 (Stop misusing the 'information' error severity!)

Current implementation tries two alternatives. Without all headers or with all headers and prints out the option with
less code. In future versions this could try with individual headers or group of header files.

Kimmo Varis cfcfa3f000 Use "enabled" list for the style checking.
Settings-class currently enables style checking via dedicated
boolean attribute. All other CLI's enable-options are handled
through the enable-list. This commit moves style-check enabling
to use the enable-list.

Main advantage is the consistency how options are handled/stored
in the Settings class. Which also unifies using them for the other
code. You need to enable certain type of checks? Use the
addEnabled()-method. You want to check if certain type of checks
are enabled? Use the isEnabled()-method.

Reijo Tomperi 89fd5bacf9 Fix #2849, False positive: memory leak (using question mark operator)
http://sourceforge.net/apps/trac/cppcheck/ticket/2849
Simplify: *d = b ? b : a; into if-else
Simplify { ; { ; } } into { ; }
Removed one memleak test which should be redundant now as question marks
should not get into memleak check.
