We should not use typedefs in U-Boot. They cannot be used as forward
declarations which means that header files must include the full header to
access them.
Drop the typedef and rename the struct to remove the _s suffix which is
now not useful.
This requires quite a few header-file additions.

Trying to extend 'adtimg' functionality [1], we've been severely hit
by a major limitation in the command's usage scheme. Specifically, the
command's user interface appears to be too centric to getting the
DTB/DTBO entry [3] based on the index of the desired DT in the image,
which makes it really difficult retrieving the DT entry based on
alternative criteria (e.g. filtering by id/rev fields), the
latter being demanded by real life customer use-cases [1].
This went to the point of receiving below feedback from Sam [2]:
-- snip --
As for 'dtimg' command: after giving it some thought, I think not much
people using it yet. So in this particular case I don't have some
strong preference, and if you think the 'dtimg' interface is ugly, and
it overcomes "don't break interfaces" rule, maybe now is a good time
to rework it (before it gets widely used).
-- snip --
Given the above, rework the usage pattern from [4] to [5], in order to
allow an intuitive enablement of "by id|rev" DT search [6].

[4] Old usage
adtimg dump <addr> - Print image contents
adtimg start <addr> <index> <varname> - Get DT address by index
adtimg size <addr> <index> <varname> - Get DT size by index
[5] New usage
adtimg addr <addr> - Set image location to <addr>
adtimg dump - Print out image contents
adtimg get dt --index=<i> [avar [svar]] - Get DT address and size by index
[6] Soon-to-be-provided "by id|rev" add-on functionality
adtimg get dt --id=<id> --rev=<rev> [avar [svar [ivar]]]
- Get DT address/size/index by id|rev fields

With 'dtimg.c' renamed to 'adtimg.c', now ensure the naming
consistency in the internal implementation of 'adtimg.c'.
No functional change intended.

Rename the existing 'dtimg' command to 'adtimg', in order to:
- Suggest the Android origins and scope
- Be consistent with the upcoming 'abootimg' command (naming
suggested by Simon [*])
The change in _not_ backward compatible, but its benefits outweigh its
downsides, given that we don't expect active users of 'dtimg' today.
Perform the rename in several steps:
1. Rename *.c file and Kconfig symbol. This should allow
'git log --follow' to properly track the history of 'adtimg.c'
2. 's/dtimg/adtimg/g' in the internal namespace of 'adtimg.c'
ELF comparison [**] before and after shows no functional change.
