Convert plaintext documents to Markdown

This converts GOVERNANCE, MEMBERS and README to Markdown documents.
These are only cosmetic changes, the actual contents and wording have
been retained.

GitLab pretty-prints Markdown and adds anchors. We can now add links
from one document to another.

Unfortunately GOVERNANCE lettered lists have been converted to numbered
lists, because Markdown doesn't support the former.

the broader process for standardization of protocol extensions in the Wayland
ecosystem.

interface names from other protocols should also be avoided.

Backward compatible changes within a major unstable version can be done

Declaring a protocol stable
~~~~~~~~~~~~~~~~~~~~~~~~~~~
## Declaring a protocol stable
Once it is decided that a protocol should be declared stable, meaning no
more backward incompatible changes will ever be allowed, one last
breakage is needed.
The procedure of doing this is the following:
. Create a new directory in the +stable/+ toplevel directory with the
same name as the protocol directory in the +unstable/+ directory.
. Copy the final version of the XML that is the version that was
decided to be declared stable into the new directory. The target name
should be the same name as the protocol directory but with the +.xml+
suffix.
. Rename the name of the protocol in the XML by removing the
'unstable' part and the major version number.
. Remove the +z+ prefix and the major version number suffix from all
of the interfaces in the protocol.
. Reset all of the interface version attributes to +1+.
. Update the +README+ file in the unstable directory and create a new
+README+ file in the new directory.
- Create a new directory in the `stable/` toplevel directory with the
same name as the protocol directory in the `unstable/` directory.
- Copy the final version of the XML that is the version that was
decided to be declared stable into the new directory. The target name
should be the same name as the protocol directory but with the `.xml`
suffix.
- Rename the name of the protocol in the XML by removing the
`unstable` part and the major version number.
- Remove the `z` prefix and the major version number suffix from all
of the interfaces in the protocol.
- Reset all of the interface version attributes to 1.
- Update the `README` file in the unstable directory and create a new
`README` file in the new directory.
There are other requirements for declaring a protocol stable, see
GOVERNANCE section 2.3.
