Add autosave info tags to all the set records in ADBase and the various ...

...plugins.

This has been tested with an IOC using the ROI, Stats and Array plugins.

In the IOC startup file, to create an autosave .req file, do:

makeAutosaveFileFromDbInfo("$(SAVE_DIR)/$(IOCNAME).req", "autosaveFields")

after iocInit. This is documented in the autosave documentation.
