[toplevel] Refactor load path handling.
We refactor top-level load path handling. This is in preparation to
make load paths become local to a particular document.
To this effect, we introduce a new data type `coq_path` that includes
the full specification of a load path:
```
type add_ml = AddNoML | AddTopML | AddRecML
type vo_path_spec = {
unix_path : string; (* Filesystem path contaning vo/ml files *)
coq_path : Names.DirPath.t; (* Coq prefix for the path *)
implicit : bool; (* [implicit = true] avoids having to qualify with [coq_path] *)
has_ml : add_ml; (* If [has_ml] is true, the directory will also be search for plugins *)
}
type coq_path_spec =
| VoPath of vo_path_spec
| MlPath of string
type coq_path = {
path_spec: coq_path_spec;
recursive: bool;
}
```
Then, initialization of load paths is split into building a list of
load paths and actually making them effective. A future commit will
make thus the list of load paths a parameter for document creation.
This API is necessarily internal [for now] thus I don't think a
changes entry is needed.
