Changeset a52104c in rtems-libbsd for freebsd-to-rtems.py

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.
