Ingo Weinhold 76a8ec23db * Added disk system flags for whether a partition name and partition
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.
