Wire up the source side of postcopy migration over TCP. When
`mode=postcopy` is requested on vm.send-migration, the source skips
the pre-copy dirty-tracking loop and lets the destination resume early,
then serves guest pages on demand over a dedicated connection.

I've added newlines between paragraphs and code blocks for easier
reading. I've also changed the code blocks to use the correct
highlighting.

To enable live-migration for vhost-user devices, we now always shutdown
the source VM when the migration is completed. This patch reflects this
change in the documentation.
