Non-existing include path is not a fatal problem requiring exiting
the program. Instead we just print a warning and remove the non-
existing include path from the list.
Add support for giving list of ignored paths from CLI. This way
user can define paths one doesn't want to check (like generated
code). This first simple implementation only does exact matching,
no support for wildcards etc. And matching is always agains dir
names.
If the filtered dir name is part of the checked filename then the
file is ignored.
Ticket #1690 (Ability to exclude files and directories from checks)
Ticket #2441 (Parsing of command line arguments breaks after --errorlist)
Instead of stopping processing command line options after
--errorlist process them all. This way e.g. --verbose can be given
also after the --errorlist.
Fix ticket #2496 (Is error reporting for an unneeded parameter wrong?)
There are several command line options / commands after which we
don't want Cppcheck to even try to open any files. Eg. printing
help or listing errors. So add new attribute for CmdLineParser to
track use of these options and exit before checking files when
the attribute is set.
Convert include path to use internal path separators when parsing
command line. Convert back to native separators when using paths.
