Nam Cao 97ffa4ce6a verification/rvgen: Add support for linear temporal logic
Add support for generating RV monitors from linear temporal logic, similar
to the generation of deterministic automaton monitors.

Nam Cao cce86e03a2 verification/rvgen: Restructure the classes to prepare for LTL inclusion
Both container generation and DA monitor generation is implemented in the
class dot2k. That requires some ugly "if is_container ... else ...". If
linear temporal logic support is added at the current state, the "if else"
chain is longer and uglier.

Furthermore, container generation is irrevelant to .dot files. It is
therefore illogical to be implemented in class "dot2k".

Clean it up, restructure the dot2k class into the following class
hierarchy:

         (RVGenerator)
              /\
             /  \
            /    \
           /      \
          /        \
    (Container)  (Monitor)
                    /\
                   /  \
                  /    \
                 /      \
              (dot2k)  [ltl2k] <- intended

This allows a simple and clean integration of LTL.

Nam Cao b6c62aa791 verification/dot2k: Prepare the frontend for LTL inclusion
The dot2k tool has some code that can be reused for linear temporal logic
monitor. Prepare its frontend for LTL inclusion:

  1. Rename to be generic: rvgen

  2. Replace the parameter --dot with 2 parameters:
     --class: to specific the monitor class, can be 'da' or 'ltl'
     --spec: the monitor specification file, .dot file for DA, and .ltl
             file for LTL

The old command:

  python3 dot2/dot2k monitor -d wip.dot -t per_cpu

is equivalent to the new commands:

  python3 rvgen monitor -c da -s wip.dot -t per_cpu
