Pietro Fezzardi 306e8a93f1 Add OpaqueTypePrefix to model schema 
Add an OpaqueTypePrefix string to the model configuration with
default `opaque_type_`. This is used to build the C name of the
artificial structs that wrap model array types and keeps the prefix
configurable alongside the other artificial-name prefixes.

doc: |-
A list of binaries used in this project. Currently only limited to 0
or 1 elements.
This is currently optional and a Model is valid without any Binaries
specified. This is done as a transitional measure as the new
experimental pipeline is implemented. Eventually this limitation will
be lifted and each element of `Segments` will need to reference a
binary present in `Binaries`.
Do note that, even in this transitional phase, running some pipes in
the new experimental pipeline will lead to an error being thrown if
`Binaries` is empty.

- name: ExtraCodeAddresses
doc: |-
A list of addresses known to contain code.
rev.ng is usually able to discover all the code by itself by recursively
visiting the control-flow graph of functions and the call graph.
However, certain pieces of code cannot be identified through these
techniques.
A prime example are the addresses of `catch` blocks of C++ exception
handlers: no code ever directly jumps there and their address is not
stored in jump tables. Their address can only be obtained by interpreting
metadata in the ELF.

# Type definition system

- name: TypeDefinition
type: struct
doc: |-
Base data structure for all the type definitions.
A type definition differs from a `Type` in the fact that it has an identity.
In fact, while two identical instances of `Type` can be considered to be the
same `Type`, two instances of a `TypeDefinition` that only differ from their
`ID` are two distinct types.
A type definition can be a `struct`, a `union`, a `typedef`, an `enum` or a
function prototype.

The function type described through a C-like prototype plus an ABI.
This is an "high level" representation of the prototype of a function. It is
expressed as list of arguments composed by an index and a type. No
information about the register is embedded. That information is implicit in
the ABI this type is associated to.
In contrast, a `RawFunctionType` is not associated to any ABI and explicitly
describes, among other things, what registers are used to pass arguments and
return values.

doc: The C ABI associated to this function type.
type: ABI
- name: ReturnType
doc: The function return type.

A comment that will be emitted as part of this function's definiktion
in the `\returns ${COMMENT_TEXT}` shape.

This must only ever be set to a `PrimitiveType` with either
an `Unsigned` or a `Signed` kind.

`enum` entry.
type: string
- name: RawFunctionDefinition
inherits: TypeDefinition
type: struct
doc: |-
The function type described by explicitly listing how arguments and return
values are passed.
This is a "low level" representation of the prototype of a function. Where
the list of registers used to pass arguments and return values is explicitl.
For stack arguments, they are collected in a single `struct`
(`StackArgumentsType`).
In contrast, a `CABIFunctionDefinition` expresses the function type from a
high-level perspective (e.g., a single argument might span multiple registers)
and his associated to a well-known ABI. Given an ABI, it is always possible
to convert a `CABIFunctionDefinition` into a `RawFunctionDefinition`.

by 8.

doc: |-
A modification of the 32-bit `__cdecl` Microsoft ABI for x86 processor
architecture
([reference](https://docs.microsoft.com/en-us/cpp/cpp/stdcall)).
The main difference is the fact that the callee is responsible for stack
cleanup instead of the caller.

doc: |-
A modification of the 32-bit `__stdcall` Microsoft ABI for x86 processor
architecture
([reference](https://docs.microsoft.com/en-us/cpp/cpp/thiscall)).
The main difference is the fact that it allows to pass a
single (the first) function argument using a register. This ABI is only
used for member function call where the first argument is always a `this`
pointer.

A [`Segment`](#Segment) can specify a set of *canonical values* for certain

This can be used to represent concepts such as the global pointer, which in
certain ABIs, is not set by each function, but it's possible to assume it has
a certain value at the entry of the function.
