Parameterize architecture-specific details

Abstract architecture details into architecture.h and add x86 constants.
This is slightly complicated by the fact that 64-bit hosts can run
32-bit code, so we do still need to resolve some values dynamically.

The architecture_info() function is intented to address this, and
performs parameter lookups based on the current state of the guest
process.

Resolving values on a per-process-state basis is important due to the
process model under Linux.  If we fork to debug a 32-bit program, the
forked process will be native 64-bit until the execve system call.  And
of course, the process is then free to exec anything it likes later on
as well.
