Add the -c option for specifying the capacity of the disk image. When a capcity is given, no partitions are required. When no partitions are given, no scheme needs to be specified either. This makes it possible to create an entirely empty disk image. To add an empty partitioning table, specify the scheme.
Bump the version to 20150222.

Don't require a scheme if no partitions are given. Change the code to handle that case. Note that we still require partitions, so the change is effectively a no-op.

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.

Update the usage message and the man page to account for the new long options. Bump the version number to 20140927. While here, use explicit fputc() calls to skip a line in the output. This to avoid having to hunt for extra '\n' characters in the printf format strings.

Add VHD support to mkimg(1). VHD is used by Xen and Microsoft's Hyper-V among others.
Add an undocumented option for unit testing (-y). When given, the image will have UUIDs and timestamps synthesized in a way that gives identical results across runs. As such, UUIDs stop being unique, globally or otherwise.

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.

1. When calculating block addresses, round to the physical block size. 2. Replace scheme_first_block() & scheme_next_block() with scheme_metadata(). When we round to block sizes, we can't reliably fixup any miscalculations. 3. In scheme_write, calculate ncyls (number of cyclinders), based on the total size, sectors/track and number of heads. 4. Add verbosity when constructing the partitions. This includes the starting block address and size in bytes and blocks. 5. Add verbosity about the sectors/track and number of heads.

First batch of media control: 1. Change -h to -H and change -t to -T. Use -H to specify the number of heads and -T to specify the track size (number of sectors per track). 2. Add -S and -P. Use -S to specify the logical sector size and -P to specify the physical sector size.
Default to 512 for both the logical and physical sector size. Set nheads and nsecs to 1 by default.

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.

Add mkimg.h. It contains the 'part' structure definition and the linked list (STAILQ) so that it can be shared and re-used in all source files. Replace the now unneeded scheme_add_part() with scheme_check_part() for posterity.
Also (should have been a separate commit), remove the enforcement of creating a GPT table with at least 128 entries. While this is generally advised as the default or minimum, it's not actually a hard requirement. We now recreate a table that's precisely enough (rounded of course).

Safe WIP: mkimg is a user-space utility for creating disk images. In its current form and shape, it creates images with the correct partition contents and overall image layout. What it doesn't do yet is actually scribble the metadata, such as partition tables and boot code. This is where I'd like to leverage code from other places, such as geom_part, and if possible/feasible. Also, the utility should be a little bit smarter about files and pipes so that we create temporary files only when needed (e.g. when we don't know the size of a partition's contents in advance while wrting the image to stdout).
