Gary Benson 125f8a3dde Move shared native target specific code to gdb/nat
https://sourceware.org/gdb/wiki/Common describes the following
directory structure:

 gdb/nat/
   Native target backend files. Code that interfaces with the
   host debug API. E.g., ptrace code, Windows debug API code,
   procfs code should go here.

 gdb/target/
   Host-independent, target vector specific code (target_ops).

 gdb/common/
   All other shared code.

This commit moves all native target backend files currently in
gdb/common to gdb/nat.
