PR 2012 - mdump/wdump shell cmds handle length arg incorrectly; add ldump cmd

Browse Source 
* libmisc/shell/main_mdump.c: Reworked to fix bugs in handling of the
	length argument and to provide an "ldump" command.  This file now also
	supports the "wdump" command.  In addition, an RTEMS API function called
	rtems_mdump() is provided to allow easy dumping from application code.
	* libmisc/shell/main_mwdump.c: Obsolete file.
	* libmisc/Makefile.am: Removed main_mwdump.c
	* libmisc/shell/shellconfig.h: Added "ldump" command.
	* shell/memory.t: Added documentation for the "ldump" command
