[PATCH v4 06/83] buildman: Avoid globals in leaf functions

[Simon Glass]

Rather than using the global thoughout each function, pass in these
values. This allows tests to use different values when testing the same
functions.

Improve a few comments while we are here.

No functional change is intended.
