The QMP dump API represents the dump format as an enumeration. Add three new enumerators, one for each supported kdump compression, each named "kdump-raw-*". For the HMP command line, rather than adding a new flag corresponding to each format, it seems more human-friendly to add a single flag "-R" to switch the kdump formats to "raw" mode. The choice of "-R" also correlates nicely to the "makedumpfile -R" option, which would serve to reassemble a flattened vmcore.
