* Test case for LockedFreePort not colliding with port 0

* Discover dynamic port range on Linux
* Random port generator outside ephemeral range
* remove dev comments
* Draw FreePort from outside the ephemeral port range
Note, there is a race condition between the socket being closed and the
lock-file being created in LockedFreePort. This is not a new issue, it
was already present with the previous port 0 based implementation.
LockedFreePort handles this by attempting to find a free port and taking
a file lock multiple times.
But, it could happen that A `find`s port N, and obtains the lock, but
doesn't bind port N again, yet; then B binds port N during `find`; then
A attempts to bind port N before B could release it again and fails
because B still holds it.

This PR updates scalafmt and enables trailingCommas =
multiple. Unfortunately, scalafmt broke the version field which means
we cannot fully preserve the rest of the config. I’ve made some
attempts to stay reasonably close to the original config but couldn’t
find an exact equivalent in a lot of cases. I don’t feel strongly
about any of the settings so happy to change them to something else.
As announced, this will be merged on Saturday to avoid too many conflicts.

* Add a Scala 2.13 build pipeline
This adds initial support for multiple Scala versions controlled via
the DAML_SCALA_VERSION env var and a CI job to make sure we don’t
regress. For now we only test //libs-scala/ports/... which seemed like
the easiest starting point I could find. We can incrementally expand
that over time.

* Upgrade Scala dependencies for 2.13 compatibility
This upgrades a bunch of Scala libraries to versions that have 2.13
support. There are two libraries that are still missing:
- diffson, this has a new version but with significant breaking
changes and it is only used in Naigator console which I hope to kill
before I have to worry about this.
- ai.x:diff, this is used in the ledger API test tool. The library is
abondened but there are a few alternatives.

This is necessary to at least attempt an upgrade to 2.13 and
generally, I want to keep our rulesets up2date. rules-scala forces the
version of scalatest so we have to bump that at the same time.
This requires changes to basically all Scala test suites since the
import structure has changed and a bunch of things (primarily
scalacheck support) got split out.
Apologies for the giant PR, I don’t see a way to keep it smaller.

* reenable 'restart triggers after shutdown'
CHANGELOG_BEGIN

* wait for everything to shut down before completing a withTriggerService fixture
- similar to a change to HttpServiceFixture.withHttpService in #4593,
but without the suppression of shutdown errors
* label the WithDb tests
* in CI, test only 'recover packages after shutdown', 50 times
* experiment: Process#destroy appears to be async
* is it in the in-between period?
* partial -> total
* replace some booleans with assertions for better error reporting
* make triggerLog concurrent
* close channel and file in other error cases for port locking
- suggested by @leo-da; thanks
* use port locking instead of port 0 for trigger service fixtures
* destroy one service at a time
* missed continuation in build script
* use assertion language for "restart triggers with update errors"
* Revert "is it in the in-between period?"
This reverts commit 211ebfe9d2.
* use better assertion language for "restart triggers with update errors"

* participant-integration-api: `GrpcServerOwner` -> `GrpcServer.Owner`.
Mostly so I can create a test class named `GrpcServerSpec`.
* ports: Move the free port search from postgresql-testing.
* participant-integration-api: Test the basics of GrpcServer.
This uses the HelloService to make sure the server behaves normally.
* ledger-api-client: Extract out channel configuration from LedgerClient.
So we can test it independently of the LedgerClient itself.
* ledger-api-client: Increase the default maximum inbound header size.
Increased from 8 KB to 1 MB.
* participant-integration-api: Reduce the maximum error message size.
Truncate GRPC error descriptions to 256 KB.
* participant-integration-api: Use `Port.Dynamic` instead of `FreePort`.
In tests.
* participant-integration-api: Explicit null checks when they're shorter.
Co-authored-by: Stefano Baghino <43749967+stefanobaghino-da@users.noreply.github.com>
* ledger-api-client: Reduce the max inbound message size back to 8 KB.
And reduce the maximum size of an error description pushed out by the
server accordingly.
CHANGELOG_BEGIN
- [Integration Kit] Truncate GPRC error messages at 4 KB. This ensures
that we won't trigger a protocol error when sending errors to the
client.

will be deleted on graceful shutdown
* Relying on `java.nio.file.FileAlreadyExistsException` to determine the
case when failed due to the nonunique file name.
* toString instead of Exception.getMessage
java.nio exception's getMessage can be just a file name, need the class
name to capture the error context.
* updatePortFile -> createPortFile
* write to file instead of write into file
Packages com.digitalasset.daml and com.daml have been unified under com.daml
Ledger API and DAML-LF DEV protos have also been moved from `com/digitalasset`
to `com/daml` on the file system.
Protos for already released DAML LF versions (1.6, 1.7, 1.8) stay in the
package `com.digitalasset`.
CHANGELOG_BEGIN
[SDK] All Java and Scala packages starting with
``com.digitalasset.daml`` and ``com.digitalasset`` are now consolidated
under ``com.daml``. Simply changing imports should be enough to
migrate your code.
CHANGELOG_END
* Use com.daml as groupId for all artifacts
CHANGELOG_BEGIN
[SDK] Changed the groupId for Maven artifacts to ``com.daml``.
CHANGELOG_END
* Add 2 additional maven related checks to the release binary
1. Check that all maven upload artifacts use com.daml as the groupId
2. Check that all maven upload artifacts have a unique artifactId
* Address @cocreature's comments in https://github.com/digital-asset/daml/pull/5272#pullrequestreview-385026181
* http-json: Ask for a free port by specifying port 0.
This will avoid race conditions.
* bindings-akka-testing: Delete RandomPorts; it's unused.
* ports: Fix the Bazel test glob.
* ports: Move FreePort to postgresql-testing and add a test case.
* postgresql-testing: Make `FreePort.find()` return a `Port`.
* postgresql-testing: Lock free ports until the server starts.
This uses a `FileLock`, which should work well on all our
supported operating systems as long as everyone agrees to use it.

* postgresql-testing: Try to find a free port 10 times, then give up.

* extractor: Use `Port` for the server port.
* ports: Make Port a compile-time class only.
* ports: Allow port 0; it can be specified by a user.
* ports: Publish to Maven Central.
* Avoid opening a server to the world when finding a free port.
This is very annoying on macOS because we get a focus-stealing popup for
a split second, asking for permission to allow the server through the
firewall. The popup pretty much always disappears before it can even be
read, when the server is closed.
This is almost certainly not an attack vector, because:
- we only do this in tests,
- the server is open for only a few milliseconds,
- nothing is served,
- and finding the port is tricky, because it's effectively random.
Nevertheless, it's very annoying.
CHANGELOG_BEGIN
CHANGELOG_END
* Extract a Bazel package for finding free ports.
We seem to do it in 4 different places, which I think is enough to
remove the duplication.
