This commit adds support for the Cppcheck analyzer.

The following two commits are also squashed into this:
* [test] Add new test cases for Cppcheck support
* [analyzer] Check version compatibility

This commit is the resurrection of works made by Márton Csordás.
The original pull request Ericsson#2290 had three more refactoring related change
sets which were omitted in this. Some changes were added in compared to
the original commits:
* The Cppcheck report converter is used to get the results in the
result_handler.
* The hash calculation logic has been uplifted to the latest one.
* Some small small compatibility changes were added because of the
changes in the code base.

This patch is a work in progress, there are debug prints all over the
place inside Codechecker, treat it accordingly. Will be amended, and
split up, when I am back from vacation.

Cppcheck now works in a raw directory instead of directly into the
workspace folder.
Exponential explosion of reports in plist files are now fixed.
Checker disable now works on native levels.
The `--disable <cppcheck_check>` now properly translates to `--suppress
<cppcheck_check> in the cppcheck invocation.
The current run configuration of cppcheck is `--enable=all`.

Added two new input paramaters:
With `cppcheck-addons` extra cppcheck checkers can be specified.
With `cppcheck-libraries` the cppcheck library definitions can be added.

Cppcheck reports have to be "fixed" for Codechecker to be able to
properly interpret them. The actual error message must be added to any
multistep report as a last bug path event.

Cppcheck checkers are prefixed with the `cppcheck-` prefix.

Newer version of Cppcheck may include some kind of an ID in the
output plist filename, so the renaming/moving logic needed to be
refactored to be able to work with new Cppcheck releases.

Codechecker will incorrectly use the reports folder path, during the
creation of reports, when the source directory is not supplied.
