Refactor the binary import and dependency resolution infrastructure to
support multiple platforms (Linux, Windows, macOS) via a
configuration-driven root system.
Major changes:
* Overhaul PDB and DWARF importers for platform-aware debug info
loading.
* Refactor LDDTree into a template-based architecture with
platform-specific implementations (ELF, PE/COFF).
* Mostly rewrite the PDB importer, which had significant limitations.
This commit ensures relocations imported from PE/COFF binaries have
generic `Address`. The fact that this was not the case lead to not
detecting dynamic calls.
The commit also improves logging and fixes the handling of maximum depth
visit of the PDB importer.
Fix the behavior of binary importers by propagating the path of the
input binary from revng2 downwards, allowing finding `.debug` files in
the correct paths.
This commit ensures that parts of the model that must point to code
(specifically `Binary::EntryPoint`, `Binary::ExtraCodeAddresses` and
`Function::Entry`) actually point to a segment mapped as +x.
Make the cache directory logic uniform in Python and C++, move the
respective implementations under support since it's project-wide logic
and not exclusive to debug-info.
A class or a struct type A can be a forward declaration and refer
to another type B in PDB, so we need to follow the references.
We pre-create type for B, when we face type A, and then, when we
visit type B, we populate the fields for the model::type we
pre-created.
In addition, this patch fixes some minor/side bugs:
- Handle SHORT/Int16Short simple type
- Do not delete model::Function if Prototype is invalid.
