Add mkimg_chs() for those schemes that need the LBA broken down into cylinder, head and track numbers. Return ~0U for these values when mkimg wasn't given both -T and -H (i.e. no geometry) or the cylinder would be larger than the provided maximum.
Use mkimgs_chs() for the EBR, MBR and PC98 schemes to fill in the appropriate fields. Make sure to use a "rounded" size so that the partition is always a multiple of the track size. We reserved the room for it in the metadata callback so that's a valid thing to do.
Bump the mkimg version number. While doing that again: have mkimg.o depend on the Makefile so that a version change triggers a rebuild as needed.

Fix partition alignment and image rounding when any of -P (block size), -T (track size) or -H (number of heads) is given: o scheme_metadata() always rounded to the block size. This is not always valid (e.g. vtoc8 that must have partitions start at cylinder boundaries). o The bsd and vtoc8 schemes "resized" the image to make it match the geometry, but since the geometry is an approximation and the size of the image computed from cylinders * heads * sectors is always smaller than the original image size, the partition information ran out of bounds.
The fix is to have scheme_metadata() simply pass it's arguments to the per-scheme metadata callback, so that schemes not only know where the metadata is to go, but also what the current block address is. It's now up to the per-scheme callback to reserve room for metadata and to make sure alignment and rounding is applied.
The BSD scheme now has the most elaborate alignment and rounding. Just to make the point: partitions are aligned on block boundaries, but the image is rounded to the next cyclinder boundary.
vtoc8 now properly has all partitions aligned (and rounded) to the cyclinder boundary.

MFuser/marcel/mkimg: Add support for different output formats: 1. The output file that was previously written is now called the raw format. 2. Add the vmdk output format to create VMDK images.
When the format is not given, the raw output format is assumed.

Add mkimg_write() which combines lseek(2) and write(2) and uses sector granularity for both offset and length. Have all schemes use mkimg_write() instead of mkimg_seek() followed by write(2).
Now that schemes don't use lseek(2) nor write(2) directly, it's easier to support output formats other than raw disks.

Add mkimg, a utility for making disk images from raw partition contents. The partitioning scheme can be one of the schemes supported by gpart.

Allow schemes to specify a maximum sector size. The minimum is fixed at 512. This allows checking of the sector size up-front when given on the command line.

Mostly implement the pc98 scheme. The partition table has no LBA fields at all, so we're entirely dependent upon CHS addressing. And CHS addressing is what needs more work.

Revamp: 1. Make secsz globally visible. 2. Have all code use the global secsz and nparts, rather than passing them around. 3. Introduce lba_t as the type to use when talking about block addresses. 4. Work on LBAs instead of offsets. There's just too much division with the sector size and there's really no value to use by offsets other than that is what lseek() wants. For that we now have mkimg_seek().
The bigger picture is that geometry (cylinders, heads, sectors/track) and also a possible physical sector size are to be globals that can be used from anyway. We really don't want to pass all that stuff as arguments to functions and then add __unused for most of them...

Add a scheme-specific write callback to write the metadata. While here: 1. Move FreeBSD-specific headers to a more centralized place, so that it's easier to port mkimg. 2. Remove inclusion of <uuid.h> where we don't need it (copy-pasted). 3. Check the partition data given on the command line before we do any I/O. 4. Add scheme_round() for rounding the partition size. 5. Have scheme_write call the scheme-specific write callback and have it propagate errors back to the caller.

Replace *_get_leader() and *_get_trailer() with a single *_metadata(). This single function takes a where argument to indicate the kind of metadata to "size". This way we can also get rid of the "padding" field in the scheme structure. This should make it a little more understandable what's going on.

Use linker sets to provide build-time selection of the schemes that need to be supported. Each scheme provides data and callbacks for handling the scheme-specifics. To this end, put each scheme in its own source file.
