The .affects() method of the CVE class in support/scripts/cve.py can
return 3 values: CVE_AFFECTS, CVE_DOESNT_AFFECT and CVE_UNKNOWN.
We of course properly account for CVEs where .affects() return
CVE_AFFECTS, but the ones for which CVE_UNKNOWN is returned are
currently ignored, and therefore treated as if they did not affect the
package.
However CVE_UNKNOWN in fact indicates that the v_start/v_end fields of
the CPE entry could not be parsed by
distutils.version.LooseVersion(). Instead of ignoring such cases, this
commit adds support for the concept of "unsure CVEs", which will be
listed next to CVEs known to affect the package, so that we are aware
of them and can investigate the version issue.
