ldm.txt: standardize document format 



Each text file under Documentation follows a different
format. Some doesn't even have titles!

Change its representation to follow the adopted standard,
using ReST markups for it to be parseable by Sphinx:

- Reformat its title;
- Use :Author: and :Last Updated: for authorship
- Use note markup;
- Reformat table to match ReST standard;
- Use bulleted lists where needed.

The LDM Database may not store the partitions in the order that they appear on

disk, but the driver will sort them.

To enable LDM, choose the following two options: 



  "Advanced partition selection" CONFIG_PARTITION_ADVANCED

  "Windows Logical Disk Manager (Dynamic Disk) support" CONFIG_LDM_PARTITION

  - "Advanced partition selection" CONFIG_PARTITION_ADVANCED

  - "Windows Logical Disk Manager (Dynamic Disk) support" CONFIG_LDM_PARTITION



If you believe the driver isn't working as it should, you can enable the extra

debugging code.  This will produce a LOT of output.  The option is:



  "Windows LDM extra logging" CONFIG_LDM_DEBUG

  - "Windows LDM extra logging" CONFIG_LDM_DEBUG



N.B. The partition code cannot be compiled as a module.
