Keep track of the last active slot in the shared ProcState array, so
that search loops only have to scan that far and not through all maxBackends
entries. This eliminates a performance penalty for setting maxBackends
much higher than the average number of active backends. Also, eliminate
no-longer-used 'backend tag' concept. Remove setting of environment
variables at backend start (except for CYR_RECODE), since none of them
are being examined by the backend any longer.
