QFileSystemMetaData: filling up

Changes to QFileSystemMetaData resulting from implementing
QFileSystemEngine::fillMetaData on Unix -- commit to follow.

* Added missing operators for MetaDataFlags
* Tentatively sharing entryFlags and size across platforms; times and
  owner IDs are candidates
* Flags definition simplified and made stricter; unused bits are no
  longer set in masks, either
* New AliasType for Mac; AliasType and BundleType on other platforms are
  0 so they can be optimized out
* New SequentialType for files that are not regular files
* LocalDiskAttribute (LocalDiskFlag in QAbstractFileEngine) was only
  used to flag the use of a native file engine, so it's useless here
* New flags for querying owner IDs
* New method: missingFlags, to help with incremental queries
* Added accessors for known data
* New method to fill metaData from struct stat
