a52b73f9f9 Fix #3208 (Simplify pointer to standard type, C only) 
The symbol database is unavailable during token simplification
and &data[0] might return something completely different for C++.

Moved code_is_c() from checkOther to Tokenizer.

849bee8437 [PATCH] Detect suspicious use of semicolon after 'if/for/while' 
statements if they are followed by a {..} block.

Examples are:

for (int i = 0; i < 10; ++i);
{
   printf("i)";
}

or

if (i == 100);
{
   die("Wrong argument");
}

This new check is active if you enable inconclusive checks.

9270b84d64 More fixes to the label simplifier (related to ticket 3176): 
1)Simplify the labels if there are combinations of the symbols '*','&','{' and '(' after a '%var% :' and before another '%var%';
2)but do not simplify the label if it's inside an unpreprocessed macro code.

fe4ce594ce Renamed the function 'removeRedundantCodeAfterReturn' with 'simplifyDeadCode'. 
This is a preparation in order to add new features to this function (see the @todo in the tokenize header file, ticket #3113 and #3175 for details).

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!)

Fix: Do not handle code when 'return' is inside a macro. This is valid also for 'switch' code inside a macro.
