Subject: [PATCH v3 10/22] Documentation/rv: Prepare monitor synthesis document for LTL inclusion

Monitor synthesis from deterministic automaton and linear temporal logic
have a lot in common. Therefore a single document should describe both.

Change da_monitor_synthesis.rst to monitor_synthesis.rst. LTL monitor
synthesis will be added to this file by a follow-up commit.

This makes the diff far easier to read. If renaming and adding LTL info is
done in a single commit, git wouldn't recognize it as a rename, but a file
removal and a file addition.

While at it, correct the old dot2k commands to the new rvgen commands.
