content name are supported. * Added file_system_module_info::flags (analogously to partition_module_info::flags) which indicate which disk device features the FS supports. * Replaced the file_system_module_info/partition_module_info::supports_*() hooks by a get_supported_operations() hook and for partitioning systems additionally a get_supported_child_operations() hook. * Updated file and partitioning systems accordingly. * Updated fs_shell accordingly. * Updated the DDM accordingly. The syscall interface remains unchanged, though. * _user_supports_initializing_partition() also checks whether the parent partitioning system is content now. git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@22043 a95241bf-73f2-0310-859d-f6bbb57e9c96
