Apache HTTPD does NOT use Maven versioning

[pombredanne]

The current code use the univers MavenVersion for httpd advisories. This is incorrect.
The semantics and range notation from httpd are NOT the Maven ones.
See https://httpd.apache.org/security/json/CVE-2000-1204.json for instance:

  "affects": {
    "vendor": {
      "vendor_data": [
        {
          "vendor_name": "Apache Software Foundation",
          "product": {
            "product_data": [
              {
                "product_name": "Apache HTTP Server",
                "version": {
                  "version_data": [
                    {
                      "version_name": "1.3",
                      "version_affected": "=",
                      "version_value": "1.3.12"
                    },
                    {
                      "version_name": "1.3",
                      "version_affected": "=",
                      "version_value": "1.3.11"
                    },
                    {
                      "version_name": "1.3",
                      "version_affected": "=",
                      "version_value": "1.3.9"
                    }
                  ]
                }
              }
            ]
          }
        }
      ]
    }

And per https://archive.apache.org/dist/httpd/ the version seem to be mostly semver with some pre-release extra but these is NOT maven.
