583e80993a Remove the with-exceptions backend
*Disclaimer*: This is intended for discussion

My impression is that the with-exceptions backend is to be superseded by the
without-exception backend, which is more general and more efficient. Therefore,
seeing the added complexity of maintaining the two in parallel, I see no good
reason to keep the with-exceptions version now that the equivalence of their
semantics have been proved.

It will also be nice to reduce divergences between the different backends ; and
this should make further simplifications possible (e.g. some thunkings may no
longer be needed)

Of course I am ready to hear arguments in favor of keeping it, be it in the mid-
or long-term.

This patch removes the `--avoid-exceptions` flag, making it the only option, and
the corresponding `with_exceptions` variant of the dcalc->lcalc translation. It
doesn't do further simplifications.

4cec981f62 Move global options of Cli to their own module
This resolves a dependency cycle that would forbid `Cli` from using the modue
`File`, which was annoying.

3649f92975 Rework resolution of module elements
This changes the `decl_ctx` to be toplevel only, with flattened references to
uids for most elements. The module hierarchy, which is still useful in a few
places, is kept separately.

Module names are also changed to UIDs early on, and support for module aliases
has been added (needs testing).

This resolves some issues with lookup, and should be much more robust, as well
as more convenient for most lookups.

The `decl_ctx` was also extended for string ident lookups, which avoids having
to keep the desugared resolution structure available throughout the compilation
chain.

b98bad8c33 Add a --no-typing option
it is useful e.g. to be able to print intermediate ASTs when they don't type, to
debug the typing errors. This is better than commenting the typing line each
time.

Note that the option is not available on all targets (esp. not for ocaml and
python outputs ; it's allowed on the interpreters for debugging purposes but I'm
not sure if that's a good idea)

50fad76df3 Clerk: copy files to _build and run catala there
this is more consistent, avoids empty stamp files and should make things simpler
overall.

The slightly tricky `-C` option is added to Catala so that it can be run from
_build while paths to source and destination files are still specified relative
to CWD (Ninja doesn't provide string manipulation, so otherwise we would have to
explicit both the `_build/dir/` and `dir/` versions of each path).

5efa61a0ce Clerk: rewrite 'clerk runtest' to use the new lightweight lexer
* Obsolete code for included tests has been removed

* The engine uses a proper lexer and is much simplified

* An inline test in the middle of the file now only "sees" the file up to that
  point. This fixes an issue where we had spurious errors when a type error was
  added at the end of a file, and it would pop up in tests before it. This makes
  files including many tests much more practical.

* diffing and resetting the tests has been reintroduced (done at the moment in
  Ninja, but for more control (count number of failed tests, etc.) we could put it
  back into Clerk at some point

* The Catala CLI can now take an input from stdin (with the possibility to link
  a (possibly fake) on-disk file for error reporting and file locations ; this
  is useful for running tests)

dbe0990163 Rework module includes CLI in Catala
Rather than require all files to be listed on the command-line (and having to
check consistency with `> Using` directives), the main catala CLI is now a bit
more clever.

⇒ There is a new assumption that a module name definition must match the file
name (up to case and extension) — with appropriate error handling to enforce it.

In exchange, `> Using` directives are now used to more transparently lookup the
appropriate `.catala_*` interfaces and the compiled artifacts for the used modules (handling transitive dependencies), with just standard `-I` flags for when they need to be looked up in different places.

db34c9a848 Generalise the expression printer
This patch functorises the generic expression printer, in order to be able to
re-use it for end-user printing.

It makes it possible to have an end-user, localised printer that shares the code
for e.g. priority and automatic parens handling.

A generic AST rewriting that disambiguates variables (very simple to write with
bindlib) is also added and used in the OCaml backend for something safer than
just appending `_user` (-- this also handles clashing variables that could be
introduced during compilation which would have generated wrong code before this)

Finally, the `explain` plugin is adapted to use the new printer.

Ah, and `String.format_t` was tweaked to correctly print strings that might
contain unicode without breaking alignment, and should be used instead of
`format_string` or `%s` whenever unicode can be expected.

0f9ee2c72e Refacter the main Driver module
- Use separate functions for successive passes in module `Driver.Passes`
- Use other functions for end results printing in module `Driver.Commands`

As a consequence, it is much more flexible to use by plugins or libs and we no
longer need the complex polymorphic variant parameter.

This patch leverages previous changes to use Cmdliner subcommands and
effectively specialises the flags of each Catala subcommand.

Other changes include:

- an attempt to normalise the generic options and reduce the number of global
  references. Some are ok, like `debug` ; some would better be further cleaned up,
  e.g. the ones used by Proof backend were moved to a `Proof.globals` module and
  need discussion. The printer no longer relies on the global languages and prints
  money amounts in an agnostic way.
- the plugin directory is automatically guessed and loaded even in dev setups.
  Plugins are shown by the main `catala` command and listed in `catala --help`
- exception catching at the toplevel has been refactored a bit as well; return
  codes are normalised to follow the manpage and avoid codes >= 128 that are
  generally reserved for shells.

52b1c25d50 Refactor CLI to use sub-commands
The upside of this is that each command can define specific flags ; there is a
small loss of backwards-compatibility in that the command needs to be the first
argument.

`catala --help` will now only show a summary of commands, with more specific
manpages shown on `catala CMD --help`.

Another point is that the plugin interface is extended to allow plugins to be
registered as subcommands and have their own flags (this will be very useful for
adding flags to the lazy/dot/explanation plugin that has many options).

Note that no efforts has yet been made to specialise the options, the previous
type was just made global for all subcommands.

071ec35234 Command-line: use a record for the options
Should make it much easier and less error-prone to add new options. There is
still a bit of boiler-plate, but at least it's contained in the Cli.options
function and doesn't transpire in the interfaces.
