/**
 * Does some local checking of a filename.
 * If you want more specific filename checks (such as bad words, other blacklisted stuff) use the TitleBlacklist API.
 *
 * These checks are ignored when the TitleBlacklist API is available, since presumably they should be configured there instead, where it's
 * possible to update them easily and higher-quality error messages are available.
 *
 * This is an incomplete rendering of some of the meta.wikimedia.org and commons.wikimedia.org blacklist as they existed on 2011-05-05, and
 * ignores cases that are irrelevant to uploading new media images.
 *   - all regexes are case INsensitive by default
 *   - namespaces and File: prefix are removed since everything we upload is under File: anyway
 *   - noedit, moveonly, repuload is irrelevant
 *   - we can't check autoconfirmed-ness of users here, so we ignore it
 *   - Javascript doesn't have a standard way to access unicode character properties in regexes, so \p{PROPERTY}, \P{PROPERTY}, and [[:PROPERTY:]] have been changed when possible
 *     or the associated regex removed
