This patch updates the modules to blitiri.com.ar/go/spf v1.1.0.
There are no significant changes, but it's the first version which
includes go modules.
This patch updates the modules to blitiri.com.ar/go/log v1.1.0.
That version includes new APIs we will rely on in subsequent patches.
They are experimental but it should be fine for our case, and we can
adjust if they change.
This patch tidies how defaults are handled in the config, using a new
logic to allow "overriding" one config (the default) with another (the
user supplied).
It also improves how the comparisons are done in the tests, using the
more convenient "github.com/google/go-cmp/cmp" package, which also
prints nice diffs on errors.
This is in preparation for a future path where the override mechanism
will be reused.
There is a new protobuf library (and corresponding code generator) for
Go: google.golang.org/protobuf.
It is fairly compatible with the previous v1 API
(github.com/golang/protobuf), but there are some changes.
This patch adjusts the code and generated files to the new API.
The on-wire/on-disk format remains unchanged so this should be
transparent to the users.
