MFC mkimg(1) -- revisions 268159, 268134, 266556, 266514, 266513, 266512, 266511, 266510, 266509, 266176, 265468, 265467, 265462, 265170, 263926, 263924, 263923, 263919 and 263918.
Revision 267182 changed mkimg.1 alongside other unrelated manpages. The change to mkimg.1 has been applied without registering a merge of the revision. This allows a future merge of r267182 to happen.

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.

Add the fat32 and ebr aliases. The ebr alias is needed to support the EBR scheme, as it can only live inside a MBR partition of type 5 (= DOSPTYP_EXT).

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 more partition types (mostly just the FreeBSD ones) to GPT. Avoid having schemes use literal strings by introducing an enum as the intermediate representation (see geom_part).

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.

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).
