Title:
  OMSL="closed_loop" doesn't work with constant DOL

Status in EPICS Base:
  New

Bug description:
  This was incorrectly documented for the boRecord. I just fixed that in
  the wiki.

  However, I see this as yet another arbitrary limitation.

  To lift that we need a small generalisation to how we treat constant
  links. A constant link just has to remember whether it has been
  processed before. The flag gets set by dbGetLink and the like and it
  gets reset after link initialisation (so we can change the "constant"
  using a CA put to the link field). If dbGetLink finds that the link is
  constant, then it converts the value from the string stored in the
  link, but only if it hasn't been processed before. This also means
  that we can deprecate recGblInitConstantLink because it is now
  subsumed by dbGetLink.
