TypedBufferArg is a class template; instances of this template represent typed buffers in target user space that are passed by reference to an (emulated) system call.
This template provides operator overloads for convenience, allowing for example the use of '->' to reference fields within a struct type.

Allocate a buffer of type T representing the memory at target address 'addr'.
The user can optionally specify a specific number of bytes to allocate to deal with structs that have variable-size arrays at the end.
