[PATCH 0/3] update to pip from setup.py

[daniel watson]

installing offlineimap3-git on arch failed because the package assumes
"setup.py" exists in offlineimap3 source.  there is a separate patch to
fix the arch package.  while creating that patch, i noticed that
offlineimap3's own makefile also references "setup.py".  this set of
patches fixes those dead references and restores make build, clean, and
targz.  not sure what the current build process is, and i could not tell
from the documentation i found, so i guessed.  this patch series also
updates the dockerfile so docker build works for me.  after these
changes, i am able to build the docker image, and run offlineimap3 on my
arch box.  i'm open to doing something different.
