[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.

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!)

Move Suppressions class to own source files.

general is it more natural that Settings class only contains list
of suppressions and implementation is separate.
