of controllerIop.c to adc_info.c.

- Addition of FE_STAT MEDM screen with items formally in /proc files.
- Fix to channel hopping error message.

From the user perspective, key changes are in the model Parameter block settings:
- An IOP model should now be designaeted with iop_model=1
	- Previously set by adcMaster=1
- A user control application should have the adcSlave=1 parameter removed.
	- If iop_model=1 is not in the Parameter block, then RCG assumes
	  this is a user control application model.
- IOP models that send/rcv timing over the Dolphin network
	- The transmitter model Parameter block needs dolphin_time_xmit=1
	- A recevier IOP model Parameter block needs dolphin_time_rcvr=1

1) For now, the RCG will accept either ifo= or site=, eg ifo=X2 or site=X2 to designate the IFO in the cdsParameter block. This
    obviates the need for immediate changes to present Matlab control models. All new models, and eventually all old models,
    should use the ifo= designator as the site= designator will be deprecated in a TBD future release.
2) At compile time, if a model still contains the site= designator, a warning message will be written to alert user to change to ifo=.
     This is simply a warning for now.
3) I have gone thru all the RCG Perl code to change site to ifo, where appropriate.  I think things are consistent now ie site is a
     location eg lho, llo, lao, etc. and ifo is the IFO designator eg ifo=H1, L1, A1, etc.

Updated rcgversion to 4.0 in header file.
Changed mx_stream Makefile from BSD to DEFAULT Linux.

as part of /proc removal from RCG realtime code.
This is a work in progress.
