all: Simplify component message id's definition
This patch creates a new way of defining message id's that is easier and less error prone because it doesn't require so many manual changes each time a new component is defined or a new message created.

-/* NOTE: Rules for message additions
- * 1) Each instance of a message is _better_ left with a unique message ID, even
- * if the message format is the same. Reasoning is that, if the message
- * format needs to change in one instance, the other instances are not
- * impacted or the new change does not change the ID of the instance being
- * modified.
- * 2) Addition of a message,
- * - Should increment the GLFS_NUM_MESSAGES
- * - Append to the list of messages defined, towards the end
- * - Retain macro naming as glfs_msg_X (for redability across developers)
- * NOTE: Rules for message format modifications
- * 3) Check acorss the code if the message ID macro in question is reused
- * anywhere. If reused then then the modifications should ensure correctness
- * everywhere, or needs a new message ID as (1) above was not adhered to. If
- * not used anywhere, proceed with the required modification.
- * NOTE: Rules for message deletion
- * 4) Check (3) and if used anywhere else, then cannot be deleted. If not used
- * anywhere, then can be deleted, but will leave a hole by design, as
- * addition rules specify modification to the end of the list and not filling
- * holes.
+/* To add new message IDs, append new identifiers at the end of the list.
+ *
+ * Never remove a message ID. If it's not used anymore, you can rename it or
+ * leave it as it is, but not delete it. This is to prevent reutilization of
+ * IDs by other messages.
+ *
+ * The component name must match one of the entries defined in
+ * glfs-message-id.h.
