Changes by:	wysochanski@sourceware.org	2010-08-20 12:44:31

Modified files:
	libdm          : libdevmapper.h 

Log message:
	Add macro definitions to report infrastructure for character array length.
	
	Rather than hard code the size of the field, use a #define, so we can re-use.
	The #define will be needed in a future patch when we extend the reporting
	infrastructure to have 'get' and 'set' functions for each field, allowing
	lvm2app functions which query any report field.  In order to provide a
	generic lookup based on the field id, we will define a type containing this
	field id, and thus, we will need to re-use the length of this string as
	it's defined inside libdevmapper.h.

Modified files:
	libdm          : libdevmapper.h 

Log message:
	Use const char* for offset calculation
	
	As 'const' types are also passed to macro dm_list_struct_base -
	keep offset calculation with const char pointers.
	Fixes several gcc constness warnings.

Modified files:

Log message:
	Cleanup gcc warning: cast from function call of type 'struct dm_list *'
	to non-matching type 'long unsigned int'
	
	Casting pointer to long and back to pointer could be easily
	handled with just pointer arithmetic.
