* mywork/ximinez/lending-number:
  Add a distinction between a "valid" and a "representable" Number
  chore: Point xrpld symlink to rippled (6012)
  Catch up the consequences of Number changes
  Fix build error - avoid copy
  Add integer enforcement when converting to XRP/MPTAmount to Number
  Make all STNumber fields "soeDEFAULT"
  Add optional enforcement of valid integer range to Number
