* Updated wrong language definition.
* Add 'message'
* Add BigNumeric literals in Daml.
Adds support for BigNumeric literals (when available). Only literals that will fit in a single Numeric are supported for now.
I introduced the `IsNumeric t` typeclass because this is an easy way to restrict `fromRational` without moving it into its own typeclass. (Moving it into a typeclass causes some gnarly problems with the specializer -- it starts creating references to GHC.Real in an attempt to optimize the invocation, and that's a problem because GHC.Real doesn't exist in LF.)
I then added the "fromNumeric" and "fromBigNumeric" conversion functions in that class, since they seem really convenient, and it also means we could in the future make it so that any type that implements `IsNumeric` gains literals (via Numeric or BigNumeric literals). This would improve a lot of Numeric code, since it eliminates the need to annotate types so often! But for now only Numeric and BigNumeric literals are supported.

* remote pkgs: resolve package names in data dependencies via ledger
This implements part 3) of #8976.
This adds the ability to specify package names/versions in daml.yaml in
the data-dependencies stanza. They are being resolved via the project
ledger and a daml.lock lock file.
CHANGELOG_BEGIN
[remote dependencies] Package names and versions, as well as package
ID's are allowed in the `data-dependencies` list of `daml.yaml`. These
packages are fetched from the project ledger. The auto-generated
`daml.lock` file keeps track of the package name/version to package
ID's resolution and should be checked in to version control of the
project.

* Don't mark dalfs in data-dependencies as main dalfs
This causes the LF version consistency check to fail on DALF data
dependencies that were generated with a different LF version and also
occur in dalfsFromDependencies. E.g. a dalf like `daml-prim-DA-Types`
triggers this issue.
changelog_begin
- [DAML Compiler] DALFs in data-dependencies that are imported directly
now require corresponding `--package` flags to make them visible. The
reason for this is that DALFs that are data-dependencies are no longer
treated as main DALFs.

This provides variants of `dedup*` and `sort*` which rely on Daml-LF’s

Both of these seem sufficiently common that it seems worth optimizing

I realize I’m switching somewhat randomly between foldr and

to establish the benefits or downsides of one over the other properly.

This PR adds a hook in the compiler and the engine to allow easy prototyping of new features.
In particular by using this hook, one can add a new feature in 1.dev with modifying:
compiler
type checkers (both Haskell and Scala)
archive Protobuf
archive decoder
In addition of development speed, this also adds a bit of confidence, as the peaces enumerated above are not touched when adding the feature: The feature can be added by modifying only 1.dev Daml standard library and Speedy.
aa7991f8 shows a use case of this hook.

- Add `DA.Exception` module that re-exports `DA.Internal.Exception`

- Expanded the `ExceptionDesugared` test to actually throw and catch
an exception. :-)

- [Daml Script] When running Daml Script on the command line you will
now see a Daml stacktrace on failures to interact with the ledger
which makes it significantly easier to track down which of the calls

`submit`. To extend the stack trace, add `HasCallStack` constraints
to functions and those will also be included.

* Fix closure references in Daml Repl
Turns out the comment "we probably need to extend this to merge the
modules from each line" was exactly correct: If the result evaluates
to a closure (or a value including a closure), it can reference
definitions from the current module. This happens if the simplifier
lifted something out of the current definition (otherwise we have only
one and it cannot be recursive so no chance of leaking a reference).
This PR fixes this by checking whether the result references the
current module and if it does, we keep it around.
