Running Rails 7

[headius]

A checklist of issues to fix to get Rails 7 working. Additional items will be added as needed.

• release patched net-http gem that feature-checks missing parts of jruby-openssl (feature detect to make net/http usable with JRuby ruby/net-http#52)
• release JRuby support for the strscan gem (Import JRuby's strscan ruby/strscan#25)
• release JRuby support for the stringio gem (does not get used during install or generate so far) (Import JRuby's stringio impl ruby/stringio#21)
• Fix argument delegation issue (Argument delegation failing in Rails 7 #7174)

Attaching prerelease gems of net-http and strscan based on the linked PRs:

• net-http-0.2.0.gem.zip
• strscan-3.0.2-java.gem.zip

Preview releases of net-http, strscan, and stringio are now incorporated into JRuby, allowing Rails 7 to install without modification.

Unsure about the delegation issue, but it may be resolved by recent work from @enebo.

Adding some new stuff in this issue:

• Update arjdbc CI to reflect jruby-head and Rails 7.
• Update sqlite3 to reflect API changes in Rails 7
• Update pg to reflect API changes in Rails 7
• Update mysql to reflect API changes in Rails 7
• Rails unit test pass (beyond activerecord handled by driver updates in arjdbc)(this will likely get expanded out)

Rails is working pretty well, enough to scaffold and run a basic app. Only sqlite and mysql have adapters at the moment, and I'm not sure how complete they are.

Punting remaining work to 9.4.1.
