Feature Freeze Exception: Update golang-defaults to 1.17

[William Wilson]

This change is necessary because we always update to the latest Go version before each release.

Go's source does not provide a changelog, but the changes in 1.17 can be seen at https://golang.org/doc/go1.17

To test that this change will work, I have created a PPA with golang-defaults pointing to Go 1.17, and tested a rebuild of all packages listed in reverse-depends -b src:golang-defaults. I also tested the same package builds with Go 1.16.7. The PPAs can be found at

https://launchpad.net/~jawn-smith/+archive/ubuntu/golang-baseline-rebuilds
https://launchpad.net/~jawn-smith/+archive/ubuntu/golang-defaults-117

There are 19 packages (out of about 1,750) that have new build failures with Go 1.17. They are all in universe. The packages are:

gitlab-workhorse
golang-github-biogo-hts
golang-github-crewjam-saml
golang-github-gin-gonic-gin
golang-github-google-wire
golang-github-lucas-clemente-quick-go
golang-github-marten-seemann-qtls-go
golang-github-mattermost-xml-roundtrip-validator
golang-github-prometheus-exporter-toolkit
golang-github-sevlyar-go-daemon
golang-github-zclconf-go-cty
golang-golang-x-exp
golang-golang-x-sys
golang-gopkg-square-go-jose.v2
notary
packer
panicparse
syncthing
textql

I have already started creating patches to resolve these build failures.

[Steve Langasek (vorlon)]

This was already identified on the release schedule as a late toolchain change that we were going to do, and the number of build regressions is small (and fixes in progress). So this is fine.

[William Wilson (jawn-smith)]

We have decided we need to carry a patch from Go 1.16 to Go 1.17 before updating golang-defaults. The patch is for building with -buildmode=cshared on RISC-V

[William Wilson (jawn-smith)]

golang-1.17-1ubuntu2 is now in impish-release, and contains the changes to enable buildmode=c-shared on RISC-V.

The attachment "Diff from 1.16~0ubuntu1" seems to be a debdiff. The ubuntu-sponsors team has been subscribed to the bug report so that they can review and hopefully sponsor the debdiff. If the attachment isn't a patch, please remove the "patch" flag from the attachment, remove the "patch" tag, and if you are member of the ~ubuntu-sponsors, unsubscribe the team.
