ldm.txt: standardize document format

Browse source 
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.

Below we have a 50MiB disk, divided into seven partitions.
N.B. The missing 1MiB at the end of the disk is where the LDM database is
stored.

The LDM Database may not store the partitions in the order that they appear on
disk, but the driver will sort them.
When Linux boots, you will see something like:

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.
