  Log:
  Initial CAPS IPC structural encoding and decoding support.  Note that the
  kernel is uninvolved (other then in supplying the IPC mechanism).  After
  careful consideration I decided that XML was just too much overkill but that
  a human-readable format is still desireable.  The encoding format supports
  integers, strings, opaque data, arrays, and is extensible and structural.
  
  An example encoding of the struct passwd record for user 'nobody':
  
      Spasswd{F1D"nobody",F2D"%2a",F3Dfffe,F4Dfffe,F5D0,F6D"",F7D"Unprivileged%20user",F8D"/nonexistent",F9D"/sbin/nologin",FaD0}
  
  Class elements include (S)tructure, (F)ield, (D)ata, (A)rray.  Data types are
  free-form numeric (stored as hex), with the source responsible for encoding
  negative numbers with a '-', and quoted opaque data (e.g. strings).  Any
  class element may recurse using {}.  Structures and Arrays always recurse.
  Unknown recursions are ignored by the decoder (for future backwards
  compatibility).  Whitespace is allowed but most non-alpha-numeric characters
  must be %-hex-escaped.
  
  The decoder understands simple integer types, arrays, buffers, embedded
  sub-structures, and string pointer structural elements.  It does not (yet)
  understand multi-dimensional arrays, sparse element notation, or ** pointers.
  
  This is a nice, compact encoding format that can be used for both packetized
  messages and persistently-connected streams.  The initial commit only supports
  full-messages, however.
