It is convenient to be able to deal with checkpatch warnings in the same
way as build warnings. Tools such as emacs and kate can quickly locate
the source file and line automatically.

To achieve this, adjust the format to match the C compiler, and output to
stderr.

In python 3.x the iteritems() method has been removed from dictionaries,

This reverts commit 19b4a336.

Since that commit, patman generates useless patches for file removal;
"git format -D" prints only the header but not the diff when deleting
files, and "git am" always refuses such patches.

The following is the quotation from "man git-format-patch":

  -D, --irreversible-delete
    Omit the preimage for deletes, i.e. print only the header but
    not the diff between the preimage and /dev/null. The resulting
    patch is not meant to be applied with patch nor git apply; this
    is solely for people who want to just concentrate on reviewing
    the text after the change. In addition, the output obviously
    lack enough information to apply such a patch in reverse, even
    manually, hence the name of the option.

When run with the --dry-run argument patman prints out information
showing what it would do.  This information currently doesn't line up
with what patman/git send-email really do.  Some basic examples:
- If an email address is addressed via "Series-cc" and "Patch-cc" patman
  shows that email address would be CC-ed two times.
- If an email address is addressed via "Series-to" and "Patch-cc" patman
  shows that email address would be sent TO and CC-ed.
- If an email address is addressed from a combination of tag aliases,
  get_maintainer.pl output, "Series-cc", "Patch-cc", etc patman shows
  that the email address would be CC-ed multiple times.

Patman currently does try to send duplicate emails like the --dry-run
output shows, but "git send-email" intelligently removes duplicate
addresses so this patch shouldn't change the non-dry-run functionality.

Change patman's output and email addressing to line up with the
"git send-email" logic.  This trims down patman's dry-run output and
prevents confusion about what patman will do when emails are actually
sent.

Buildman normally obtains the upstream commit by asking git. Provided that
the branch was created with 'git checkout -b <branch> <some_upstream>' then
this normally works.

When there is no upstream, we can try to guess one, by looking up through
the commits until we find a branch. Add a function to try this and print
a warning if buildman ends up relying on it.

Also update the documentation to match.
