Change Details

- Just trying to boot with the original patch forced me to relax the requirement for at least one of MAP_SHARED or MAP_PRIVATE to not be applied for anonymous mappings. - I still need to write a test program that exercises these test cases.

- Just trying to boot with the original patch forced me to relax the requirement for at least one of MAP_SHARED or MAP_PRIVATE to not be applied for anonymous mappings because libthr uses MAP_ANON without a sharing mode. - I wrote a test program to exercise these various new errors as well as several normal use cases. All of the tests succeed on current HEAD, including the ones that pass invalid flags or protection that this change checks for. With the patch, the latter tests now fail.
