The module is renamed to `Mark`, and functions renamed to avoid redundancy:
`Marked.mark` is now `Mark.add`
`Marked.unmark` is now `Mark.remove`
`Marked.map_under_mark` is now simply `Mark.map`
etc.
`Marked.same_mark_as` is replaced by `Mark.copy`, but with the arguments
swapped (which seemed more convenient throughout)
Since a type `Mark.t` would indicate a mark, and to avoid confusion, the type
`Marked.t` is renamed to `Mark.ed` as a shorthand for `Mark.marked` ; this part
can easily be removed if that's too much quirkiness.
This adds a few positions to the parser, and tweaks some others, vastly
improving the reporting of some errors (inconsistent functions definitions, but
also exceptions cycles, etc.)
This is just a bunch of `sed` calls:
```shell
sed -i 's/ScopeSet/ScopeName.Set/g' compiler/**/*.ml*
sed -i 's/ScopeMap/ScopeName.Map/g' compiler/**/*.ml*
sed -i 's/StructMap/StructName.Map/g' compiler/**/*.ml*
sed -i 's/StructSet/StructName.Set/g' compiler/**/*.ml*

sed -i 's/SubScopeNameMap/SubScopeName.Map/g' compiler/**/*.ml*
sed -i 's/SubScopeNameSet/SubScopeName.Set/g' compiler/**/*.ml*
```
... and reformat
Note that this is incomplete in the case of desugared/scopelang because we only
have typing for expressions yet, and the scope/program structure is different.
The code allows passing an environment of types for scope/subscope variables in
order to resolve `ELocation` terms, but that's unused until we implement
scopelang typing at the scope level.
this patch is just a bunch of `sed` commands
```shell
cd compiler
sed -i 's/Pos.marked/Marked.pos/g' *.ml* **/*.ml*
sed -i 's/Pos.unmark/Marked.unmark/g' *.ml* **/*.ml*
sed -i 's/Pos\.get_position/Marked.get_mark/g' *.ml* **/*.ml*
sed -i 's/Pos\.same_pos_as/Marked.same_mark_as/g' *.ml* **/*.ml*
sed -i 's/Pos\.map_under_mark/Marked.map_under_mark/g' *.ml* **/*.ml*
sed -i 's/Pos\.mark/Marked.mark/g' *.ml* **/*.ml*
sed -i 's/Pos\.compare_marked/Marked.compare/g' *.ml* **/*.ml*
```
This avoids many intermediate calls to e.g. `Format.asprintf`; should result in
some cases in "more correct" use of `Format`¹, avoid the computation of unused
debug strings, and make the code more readable.
¹ for `Format` to work as expected, all intermediate calls need to go through
it. Some cases of formatting to an intermediate string then printing through Format
again are still present, but this makes the situation better.
