 * Table-driven multirecord FRU handling.
 *
 * This makes describing the contents of multi-record data much easier
 * that writing your own field handling routines.
 *
 * You describe your data by filling in layout structures.  Three
 * different structures exist:
 *
 *  struct - Defines a record node.  The top-level of a multi record
 *  is always a record node, and arrays always consist of record
 *  nodes.
 *
 *  item - These are individual data items (floats, ints, strings,
 *  etc).  You supply an array of these in a struct layout to describe
 *  the basic items in a record.
 *
 *  array - A variable-sized set of record nodes, items (or other
 *  arrays, though that is not yet implemented).  You can insert
 *  elements in the array and delete them.
 *
 * NOTE: you cannot have an array of bitfields.
