[Freeciv-Dev] (PR#9446) puppeteer commands and client game state

["Guillermo Lopez Alejos" <100030179@xxxxxxxxxxxxxxx>]

I think that puppeteer commands shall be divided into categories (the
command "move" has no sense in pre game state).

The solution could be a new layer between the parser and puppeteer's
functions. This layer could check if the issued command is appropiate
for the current game state.

The bison grammar will contain references to the check function (i.e.
puppet_check_game_state (command_id, ...) (the "..." are a variable
number of arguments)), then puppet_check_game_state() will query for the
client's game state and check if the issued comand is valid. If so,
puppet_check_game_state() will recover the correct number of arguments
from the va_arg list and call the appropiate exec_*() function.

How to resolve that "command_id" easily with bison?
