- remove GOP_SIZE_READ/GOP_SIZE_WRITE flags. they have not been used since the change. - ufs_balloc_range: remove code which has been no-op since the change. thanks Konrad Schroder for explaining the original intention of the code. - ffs_gop_size: don't extend past eof, in the case of GOP_SIZE_MEM. otherwise genfs_getpages end up to allocate pages past eof unnecessarily.
