suppress bug in source code

[gyorb]

The following annotation format should be applied above the line where the bug was reported.
The list should contain checker names or the 'all' keyword if all bugs should be suppressed during the analysis.

// codechecker_suppress[checker_name1, checker_name2] reason for suppress
// is that checker is faulty.
int i=0;
or
// codechecker_suppress[all] reason for suppress

The "reason for suppress" field should be given by the user and it is a free text that can contain any character. Only whitespace characters are not accepted. If the "reason for suppress" field is missing, a warning message will be generated in the suppress_comment the bug database.
Reasons specified in multiple lines are accepted.
