Mikhail Zaslonko a95bad6c87 zdump/dfo_s390: Support s390 DFO for vr-kernel dumps
Since memory chunks can overlap for vr-kernel dumps stored in elf
format (ngdump, zfcpdump), we need to consider this when converting to
s390 dump output format. For that sort DFI memory chunks by start
address and adjust dfo_s390 logic for identifying memory gaps.
Otherwise we might end up with bogus DFO memory chunks being created.

Mikhail Zaslonko 7b68552359 zdump: Use global header s390_dump.h
Instead of using its own DF_S390_ constants and df_s390_ structs
in df_s390.h, include those from "dump/s390_dump.h" in order to minimize
duplicates. Adjust the code, where required, to use <stdint> types
instead of those defined in zt_common.h (e.g. use uint64_t instead of u64).

Adjust zdump include statements.

Alexander Egorenkov 4bd16ba8ea zdump: Extract dfo_mem_chunk interface from DFO
The primary goal is to separate DFO code into multiple smaller modules
and make it unit testable.

This refactoring only moved the code around w/o changing any functionality.

Alexander Egorenkov 353c23a157 zdump: Include dfi_mem_chunk.h only if required
Don't include dfi_mem_chunk.h in dfi.h because not every module including
dfi.h needs it.

Alexander Egorenkov 1005e7be7e zdump: Don't use god-like C headers
Get rid of C headers which include everything. This is bad for testing and
maintainability. C files should include only what they need and no more.

Alexander Egorenkov 40d4aa38e9 zdump/dfi_mem_chunk: Rename dfi_mem_read_rc() to dfi_mem_virt_read()
The new name describes the purpose of the function better and
emphasizes its difference with the function dfi_mem_phys_read().

Alexander Egorenkov c58cfd1ec1 zdump/dfi_mem_chunk: Replace dfi_mem_read() with dfi_mem_read_rc()
Always use the function dfi_mem_read_rc() which verifies that the given
address and size fall within a valid memory chunk. We cannot trust
user's input.
