Patch 1 and 2 refactor and clarify the documentation for the way
filtering works using --bus=, --region=, and --dimm= options for all
commands.
Patch 3 adds a new --continue option to continue creating as many
namespaces as possible for the given filter spec.

While at it, fix the formatting for the first description text block from an include - the empty line at the start caused the first block to be incorrectly indented. This fixes both the dimm and region variants.

It also gives a touch point to start thinking about parallel namespace creation. The large advancements in boot time that Alex achieved were mainly from parallelizing namespace init.
