[OSSTEST PATCH 40/60] sg-report-job-history: Refactor "ALL" handling

[Ian Jackson <ian.jackson@xxxxxxxxxxxxx>]

* Make an explicit entry ALL in @branches, rather than implicitly
  processing ALL as well.

* Consequently, put explicit ALL entries in @tasks too, rather than
  putting in entries without a branch name.

* Pass ALL to processjobbranch rather than undef, and turn it into
  the internally-used undef at the start.

When used with --flight (findflight), this has no functional change.
When used with --job, ALL must now be included in the branch
list passed to --branches.  The only in-tree call is with --flight.
