PRM and SRM model updates

Following on Filiberto's upgrade of the M2 driver boxes on PRM and SRM per alog 7630, I updated the h1susprm and h1sussrm models to match, piggybacking on his work permit 4117:

* I changed the PRM and SRM blocks at the top level to use the MC_MASTER part (as for MC2 which was modified earlier) rather than HSTS_MASTER.

* Per Stuart's suggestion, I terminated the three new outputs MC_X_M*_OUT on the new part (rather than feeding them into an IMC block as for MC2).

* I copied the matching M2_COILOUTF filter definitions from the latest copy of L1SUSMC2.txt in the SVN after checking that they corresponded to LLO alog 4495.  (Ideally I would have gotten them from H1SUSMC2.txt, but it appears we've never updated them there. I held off doing that at this time because it will need a separate WP and because there's a risk of breaking the IMC locking if something is counting on the existing poor compensation, but we should get to it soon, after we confirm that it's working for PRM and SRM.)

* I rebuilt and restarted both models. h1sussrm came up with no problems except for a few bad entries in the safe.snap, which I corrected. (There were lines like H1:SUS-SRM_M1_DAMP_L_STATE_GOOD 1 H1:SUS-SRM_M1_DAMP_L_STATE_GOOD 100676356" which were hangovers from a faulty script used at one time. I deleted the first half of each line. The PRM safe.snap had the same issue, but BURT didn't complain (see next item). I fixed it in the same fashion anyway.)

* Initially the PRM model showed a red DC bit and many of the EPICS values were not properly initialized. I realized after posting the initial version of this alog that I hadn't saved after the last edit, so the MC_MASTER block was still called MC_MASTER, so all the channel names were wrong. I saved the model, rebuilt and restarted it and this time the DC bit was green. I'll follow up with Dave Barker tomorrow to see if there's any corrective action needed re the MC_MASTER channels that were being written temporarily. The hourly backup for 16:00 hours is corrupt but the 15:00 and 17:00 ones are good.

* I committed the new models, filters and safe.snap files.

My  fix of yesterday for the dud lines in the PRM and SRM safe.snap files wasn't quite right - I had deleted the erroneous second copy of the channel names, but I should have left the "1":

H1:SUS-PRM_M1_DAMP_P_STATE_GOOD 1 113258548
