Buildman uses all available CPUs by default, so running more than one or
two concurrent processes is not normally useful.
However in some CI cases we want to be able to run several jobs at once
to save time. For example, in a lab situation we may want to run a test
on 20 boards at a time, since only the build step actually takes much
CPU.
Add an option which allows such a limit. When buildman starts up, it
waits until the number of running processes goes below the limit, then
claims a spot in the list. The list is maintained with a temporary file.
Note that the temp file is user-specific, since it is hard to create a
locked temporary file which can be accessed by any user. In most cases,
only one user is running jobs on a machine, so this should not matter.

A new release has been done with this version, so update it. Use the
version numbers in dependencies also.

Create the necessary files to build this new package.
It is not actually clear whether this is useful, since buildman has no
purpose outside U-Boot. It is included for completeness, since adding
this later would be more trouble.
Move the main program into a function so that it can easily be called by
the PyPi-created script.
