The name of some builtins will be exposed as part of the Exception

more obvious, before we could not rename those.
This is part of #8020

* Introduce SINCE-LF-FEATURE in integration tests.
The idea being to avoid hardcoding LF feature version numbers in the integration tests, so we don't have to remember to update them once a feature comes out of 1.dev

* Fix BigNumeric literal validation
The calculation of scale is off and fails on
0.123456 which turns into 1929 % 15625.
I don’t really like the implementation here but I’m failing to come up
with a more direct way to calculate it. I blame the fact that I
haven’t had coffee yet.

* Pattern matching for RoundingMode
- Fix the order of RoundingMode constructors in GHC.Types to match the LF built-in order. Try to match this order across all code and documentation, and added a test for this order.
- Implements pattern matching for RoundingMode. The added machinery could also be useful for solving #5753 in the future.
- Implements Show instance for RoundingMode. (Mainly so we can use them in tests.) Moved BigNumeric Show instance to GHC.Show.

* 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.

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.

* Missed some TODOs in DecodeV1
Some features, in particular daml-lf encoding features, don't make any sense to have an associated CPP flag. I made the CPP flag optional and removed these unnecessary feature flags (based mostly on whether the flags were used in the standard library).

* DAML-LF: Add interning for type to DAML-LF 1.dev
We add two new features to DAML-LF 1.dev:
* a per package list (or table) of `Type` messages, and
* a new case in the `Type` message which is an index into this table.
In combination, these two features can be used to allow DAML-LF
encoders to perform hash-consing of `Type` messages. We also change the
Haskell implementation of our DAML-LF encoder to do exactly that when
targetting DAML-LF 1.dev.
Doing this has a few benefits:
1. The DALFs produced by `damlc` get smaller: I've seen a case where
the size dropped from 69MB to 45MB.
2. DAML-LF decoders need to decode less data.
3. Decoded packages use less memory because identical structures are
now shared. This is particularly helpful in situations where we need
to keep the interface (or signature) of a package in memory for a
long time.
This PR mostly takes care of the Haskell implementation. However, we
need to make the Scala implementation of the decoder aware of the new
features as well since we have tests that load DAML-LF 1.dev into the
engine. A decoder and _targeted_ tests on the Scala side will follow
in a separate PR.

* Haskell: Add hlint rule to suggest foldl' over foldl
`foldl` is lazy in a way that almost never is what you want since it
can cause space leaks without any benefit. `foldl'` does not have this
problem. See https://www.well-typed.com/blog/2014/04/fixing-foldl/ for
more details.

Currently, the Haskell implementation of the DAML-LF type checker
first branches on the pattern and then on the type of the scrutinee.
This PR changes it to first branch on the type of the scrutinee and
then on the pattern. This allows for destructing the type of the
scrutinee only once intead of repeating it for each pattern. This
should be good for performance, which is a nice side effect of this
change.
The main reason why I'm changing this is because we want to implement
an exhaustiveness check. This seems rather complicated to achieve with
the current implementation and will be significantly easier after this
change.
This PR is purely a refactoring and does not change the semantics of
amnything. In particular, it does not touch the decision that default
patterns match on anything, even no other pattern would match on the
value.

An extraction script that makes the LF reading libraries (DAML LF archive decoding to an AST) usable in other Haskell projects.
This script once existed but is not available any more, so I have resurrected the script, adapted to current usage, and upgraded to the newest stackage LTS that can support it. These libraries _could_ be versioned manually to released SDKs and published if desirable (without making any guarantees about the stability, therefore prefixing the version with `0.`.

fixes#7114
This PR changes the Show instance of ContractId and flips the switch
on triggers and DAML Script to run in off-ledger mode.
It also adds a test that for DAML Script we actually get back the
correct contract id.
There is a bit of a design decision here in how we want to print
contract ids, so let me list the options I considered. $cid will stand
for the actual cid and all options are wrapped in markdown inline
code.
1. `"$cid"`. Indistinguishable from string. Suggests that there might
be an IsString instance for ContractId.
2. `<$cid>`. Matches the dummy `<contract-id>` but it’s not a dummy so
I don’t think matching that is benefitial.
3. `$cid`. Easy to spot (contract ids start with # and have no
spaces), clearly not a string but might look slightly weird.
changelog_begin
- [DAML Script/DAML Triggers] When using DAML-LF 1.dev, the `Show` instance of `ContractId` will now display the actual contract id instead of a dummy `<contract-id>` value. Note that this only applies to DAML Script and DAML Triggers not to ledger code.

Since Bazel 2.2.0 the order of generating `WORKSPACE` and `BUILD` files

`WORKSPACE` file will likely become invalid.

client_server_test used to produce an executable shell script in form of

`--noincompatible_windows_native_test_wrapper` this no longer works on
Windows since `.sh` files are not directly executable on Windows.
This change fixes the issue by producing the script file in a dedicated
rule and then wrapping it in a `sh_test` rule which also works on
Windows.

* damlc inspect: Add output modes with less details
This PR adds two new detail levels to `damlc inspect`:
* `--detail=-1` omits all package ids from the pretty printed output.
* `--detail=-2` omits all package ids, type information and kind
annotations from the output.
We also slightly change the existing detail level `--detail=0`, which
is the default when the `--detail` flag is omitted, to make the output
more consistent:
* Kind annotations are no longer omitted when the kind is `*` (star).
* All location information is now omitted. To get location information,
use `--detail=1`.
