[0/2] Document fsck msg ids

Here is to illustrate what I meant in my review comments on [2/2], on top of these two patches. Two structural changes worth noting are: - I removed the inclusin from config/fsck.txt because otherwise the entry for fsck.<msg-id> becomes way too long and the next entry, fsck.skipList, may become harder to find. But I am OK if you really want to make the list of msgids a sublist here, as long as it makes it clear that those with default severity FATAL cannot be configured away. That has to be done outside of fsck-msgids.txt file (in other words, in config/fsck.txt where it includes the file) as it would be a good idea to keep the file a "pure" list, to keep it easy to auto-generate in the future. - The description of each item begins with (SEVERITY) marking, as the ones that are (FATAL) cannot be configured. I think I added all error types that your patch missed. Also I added (FATAL)/(ERROR)/(WARN)/(INFO) markings to show what their default severity levels are, but I may have made mistakes. If you want to take any part of these changes, feel free to do so, but please do so after double checking. This was primarily done to illustrate how the end result should look like if I were doing this topic, and not to show how each item should be described exactly. Thanks.
