e1000 driver now compiles with fewer modifications

- Change some include path in the e1000 drivers
  - Add some files from the FreeBSD source tree (modification in
    freebsd-to-rtems.py)
    - Avoid inconsistent functions declarations: the bool_t and/or
    boolean_t are not the same between rtems and freebsd so that a
    function with the prototype bool_t foobar() and another boolean_t
    foobar() does not compile on rtems. (see if_igb.c for example)
      Joel Note: These are still inconsistent on the FreeBSD side and need
                 to be addressed by them. We will just make the prototype
                 match the body until they give us a solution.
