  Bring the dumpchan application inline with "core show channel".

  * Added fields that are in "core show channel" to dumpchan output.

  * Fixed reuse of formatbuf before the previous string stored there was
  used by snprintf.  All output strings now have their own buffer.

  * Adjusted the buffer sizes to not be so abusive of the stack now that
  there are more buffers.

  Change requested by oej.
