Series buildman: Improve summary output | expand

Commit Message

Simon Glass April 5, 2020, 3:21 p.m. UTC
At present the string for each error line is created in _CalcErrorDelta()
and used to create the summary output. This is inflexible since all the
information (error/warning character, error line, list of boards with that
error line) is munged together in a string.

Create an object to hold this information and only convert it to a string
when printing the actual output.
