Whitespace was removed from the append data for every configuration
and every file: n(configuration) * n(files).
Removing whitespace immediately after the append data was read can
significantly reduce the execution time and memory usage.
It also allows further improvement because copies to the temporary
object appendCode are no longer needed.

This is ment to be used for debugging false positive errors in Cppcheck.
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.
The "ExtraVersion" can be used for things like Git commit Id,
release tag (version control), release date etc. If the string
is empty, nothing is printed.
When user wants to see only errors printed (--quiet in CLI) we
must obey that. And not print unmatchedSuppressions list.
Ticket: #2895 (Cannot suppress unmatchedSuppression reports)
Unify usage and API of CppCheck class. Allow only one file checked
at a time, instead of list of files. Clients can then handle file
lists more naturally and as they see fit. Also clients have better
knowledge of how checking status should be handled.
The single-threaded CLI checking was only one using the file list.
Other clients were giving files (to list) one file at a time.
The "too many configurations"-message is currently only printed to the
log. So it won't be seen by users integrating Cppcheck using XML
error file. It is also easily missed in the GUI as it only shows up
in the checking log. Making it a information message it shows up
with the other errors and tells user that file was not completely
checked.
Ticket #2527 (Make "too many configurations" message an error message)
CLI and GUI already do the directory walking for us and we have list
of files to check. So we were duplicating this directory walking.
Practically doing check again for each file if it is a directory.
Which can take some time with large amount of files.
Internally we are using forward-slash and only convert to backslash
for Windows output. For suppressing we must use internal
forward-slash format of paths.
