Rainer Gerhards b44dcabe90 remove pData emulation from v8 omod interface
breaks compilation of not converted modules - but these
won't work anyways. So better change this now.

/* omshell.c
* This is the implementation of the build-in shell output module.
*
* ************* DO NOT EXTEND THIS MODULE **************
* This is pure legacy, omprog has much better and more
* secure functionality than this module. It is NOT
* recommended to base new work on it!
* 2012-01-19 rgerhards
* ******************************************************
*
* NOTE: read comments in module-template.h to understand how this file
* works!
*
* shell support was initially written by bkalkbrenner 2005-09-20
*
* File begun on 2007-07-20 by RGerhards (extracted from syslogd.c)
* This file is under development and has not yet arrived at being fully
* self-contained and a real object. So far, it is mostly an excerpt
* of the "old" message code without any modifications. However, it
* helps to have things at the right place one we go to the meat of it.
