vmware_guestdump: Various format versions support
There are several versions of debug.guest format. Current version of the code is able to parse only version 4. Improve parser to support other known versions. Split data structures on sub-structures and introduce a helper functions to calculate a gap between them based on the version number. Implement additional data structure (struct mainmeminfo_old) and logic specifically for original (version 1) format support. Signed-off-by: Alexey Makhalov <alexey.makhalov@broadcom.com>
