/**
 *  @file /src/usr/errl/display/errldisplay.C
 *
 *  @brief Implementation of ErrlDisplay class
 *         This will display human-readable dumps of error log entries.
 *
 *  The strings displayed are automatically extracted from source code by
 *  the script ../errl/parser/genErrlParsers.pl
 *
 *  The base image is limited to 512K, and inclusion of the error strings
 *  in the base make it grow beyond that limit, so the text and display
 *  functions are put into the extended image.
 *
 *  The errl module in the base image will provide an interface for the
 *  display functions to register with it.
 *  When an errl is generated, the base image will see if a display function
 *  has been registered.  If so, then it will be called to display the error.
 *  If not, then the base image will display the raw error data and save the
 *  error information into a list.
 *  When the display function does register itself, the errl module in the
 *  base image will pretty-print all of the pending errors from the list
 *  it generated before that point.
