Title:
  Array records: add initialization through "const" long string link

Status in EPICS Base:
  Fix Released
Status in EPICS Base 7.0 series:
  Fix Released

Bug description:
  For array records (waveform & friends), initialization of array data
  can be done through a const link, e.g.

  field(INP, { const: [65, 66, 67, 68] } )

  Array records of value type CHAR should also allow initialization
  through a string, so that the const link shown above can be specified
  as

  field(INP, { const: "ABCD" } )
