1. This is an important functional patch. At present, "new style" exists
only in your head. You should make an effort to justify it to everybody
else by providing a rationale in patch description.

2. You are using an integer state variable (instead of function pointers
which were self-describing by virtue of the referred function names).
Please, define an enumerated type for this state variable, giving states
human-readable, descriptive names. If you need to do state variable
arithmetic, you can provide a couple of simple, descriptive macros to
do so:

#define NEXT_STATE(s) (s + 1)

or something along the line.

3. Coding style.
