Greetings from UK! I'm here for one week now and and work and life
still needs a lot of time to settle. Thus I really appreciate you
preparing a pull request putting all the stuff in one place for me to
review and pull from. Saves a lot of my time.

I just tested the complete set with all my devices and found no
regression. Good job.
Besides some smaller comments this all looks pretty nice.

Thanks for the leak fix on this one.

All above are fine.

Might be a good idea to squeeze the overwrite fix into the file
handling commit. Its a fix for this commit anyway. Changes the other
things incremental is fine but without this squashed we would have a
regression. Especially one that overrides a user file. :/ Sure
therefore the user would need to compile it with the file IO port
patch but without the fix. Still good practice.
The fseek() for sync read/write streams was interesting, btw.

You happen to know which platforms are missing this?

Is HAVE_WINDOWS_H really the preferred way to check for windows? Satz
used ENV_WINDOWS (which also looked odd to me). Could be that it
really depends on what you are using to create the executable. MinGW
vs. Windows compiler. Anyway, as you have tested this under Windows
and I also have no problems with it under Linux thats fine.

The usage string split into three printfs looks pretty ugly to me.

For consistency I would go with a # here instead of a dot. The
non-DfuSe part of dfu-util uses it for progress indication.

I agree, its about time to rely on the functional descriptor. Lets see
if any bug reports will come for this. :)

So this is without confirmation from leaflabs, right? Its fine anyway
as it can only improve the situation. :)
The squashing of the bug fix in the previous change is the only thing
that would block me from pulling this in. If you could fix this up I
would happily pull in an updated pull request.
