make "errors" be "warnings" in process control spec

John,

I reviewed all the places in the current spec where it says something "shall be an error". For all of these, I feet it will be fine (and probably better) to say "shall generate a warning". Some of these have already been discussed in the reflector and it has been concluded that these should be made warnings instead of errors.

I include the full list below.

Thanks,

- "sync_reset_on() shall only be applicable to thread processes, it shall be an error to invoke sync_reset_on() on a method process"
- "It shall be an error to specify reset_signal_is() for a method process"
- "throwing an exception in a terminated process shall be an error if the include_descendants flag is not set"
- "Throwing an exception in a process that has not started execution yet shall have no effect for the same reasons as above, and shall be an error"
- "Throwing an exception when simulation is not running (before simulation start or after simulation end) shall have no effect and shall be an error"
- "The thrower shall always be a process. It shall be an error to throw an exception from any other context, for example from a phase callback or from the update() routine of a user defined channel"
