Drop support of obsolete dump and dump-tool versions (single-volume DASD, FBA and Tape) in order to simplify zgetdump logic: - CCW dumpers written in assembler instructions as well as stage2 dumpers of size less than 0x3000 (STAGE2_DUMPER_SIZE_V1 or STAGE2_DUMPER_SIZE_V2) haven't been used for years. Remove its traces completely as a cleanup. Keep the last version (version 5) of non-extended DASD dumper as well as newer extended DASD dumpers. - Rename STAGE2_DUMPER_SIZE_V3 and STAGE2_DUMPER_SIZE_ZLIB constants. - Drop support of non-extended s390 dumps of version < 5. Dump files of s390 format version 5 can be still produced by zgetdump (dfo_s390). - Drop excessive dump version checking in df_s390_cpu_info_add() and df_s390_hdr_add() considering that obsolete s390 dumps of version lower than 5 no longer supported. - Use cpu_cnt field in s390 dump header instead of the s390 dump version to indicate no cpu info available (DFI_CPU_CONTENT_NONE) for dfo_s390. - Make df_s390_dumper_read() return error code upon unknown dumper version/magic detection.
