Title:
  event record device support broken with constant INP

Status in EPICS Base:
  Invalid
Status in EPICS Base 3.15 series:
  Fix Committed
Status in EPICS Base 7.0 series:
  Invalid

Bug description:
  Eric Norum reported:

  ------------------ 8< ---------------------

  record(event, "$(P)$(R)reconn_") {
      field(DTYP, "Soft Channel")
      field(INP,  "55")
    field(TPRO, "1")
  }
  record(fanout, "$(P)$(R)reconnWFR_") {
      field(SCAN, "Event")
      field(EVNT, "55")
    field(TPRO, "1")
  }

  When the “reconn_” record is processed, niether ”reconnWFR_” nor any
  other record with that SCAN setup gets triggered. It’s not enough to
  set INP=55 in the .db file, I must explicitly set VAL for it to work.

  ------------------ 8< ---------------------

  The init_record() routine in devEventSoft.c (Base-3.15 branch) doesn't
  look right, I think it's missing a call to eventNameToHandle().
