/** Set the httpd-wide error message
 *
 * Often, when something fails, a 500 Internal Server Error will be emitted.
 * This is especially true when the reason is something arbitrary, like the
 * maximum header line that the httpd can handle is exceeded.  When this
 * happens, a function can set the error string to be passed back to the user.
 * This facilitates debugging.  Note that the error message will also be
 * httpd_d'd, so no need to add extra lines of code for that.
 *
 * Note that this function is not re-entrant.
 *
 * Note that at most HTTPD_MAX_ERROR_STRING characters will be stored.
 *
 * Note: no need to have a \r\n on the end of the error message.
