the methods IsFile() and GetFilePath() to BDiskDevice, and BDiskDeviceRoster::GetFileDeviceForPath(). * Added new syscalls to implement this functionality. * Added new flag B_DISK_DEVICE_IS_FILE. * Fixed wrong operator precedence assumption in the BDiskDevice class at several places. * Minor cleanup. git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@28052 a95241bf-73f2-0310-859d-f6bbb57e9c96
