[Bug 1950300] Re: Cannot use hex numbers in HW links in EPICS 7

[Andrew Johnson via Core-talk <core-talk at aps.anl.gov>]

I'd be happy with switching to from %d to %i as long as the PR includes
an entry in the Release Notes describing that change.

Title:
  Cannot use hex numbers in HW links in EPICS 7

Status in EPICS Base:
  New

Bug description:
  In EPICS 3.14.12, it was possible to use hex numbers in hardware links
  of type VME_IO and others like "#C0 S0x8b". (The parser used the
  function cvtDecimalOrHexToShort for this.) In EPICS 7 this does not
  work any longer because the string is parsed with %d instead of %i. As
  many of our existing IOCs use hex numbers here, this makes transition
  to EPICS 7 unnecessary hard.

  Changing to %i will allow hex numbers, but will also allow octal
  numbers.  That may a problem as C011 uses to mean 11 in 3.14, not 9.

  In that case, parsing with a single sscanf is not sufficient.
