Image fuzzy hashing is enabled by default. The following options have been added to allow users to disable it, if desired. New clamscan options: --scan-image[=yes(*)/no] --scan-image-fuzzy-hash[=yes(*)/no] New clamd config options: ScanImage yes(*)/no ScanImageFuzzyHash yes(*)/no New libclamav scan options: options.parse &= ~CL_SCAN_PARSE_IMAGE; options.parse &= ~CL_SCAN_PARSE_IMAGE_FUZZY_HASH; This commit also changes scan behavior to disable image fuzzy hashing for specific types when the DCONF (.cfg) signatures disable those types. That is, if DCONF disables the PNG parser, it should not only disable the CVE/format checker for PNG files, but also disable image fuzzy hashing for PNG files. Also adds a DCONF option to disable image fuzzy hashing: OTHER_CONF_IMAGE_FUZZY_HASH DCONF allows scanning features to be disabled using a configuration "signature".
