[XFS] use filldir internally
Currently xfs has a rather complicated internal scheme to allow for different directory formats in IRIX. This patch rips all code related to this out and pushes useage of the Linux filldir callback into the lowlevel directory code. This does not make the code any less portable because filldir can be used to create dirents of all possible variations (including the IRIX ones as proved by the IRIX binary emulation code under arch/mips/). This patch get rid of an unessecary copy in the readdir path, about 400 lines of code and one of the last two users of the uio structure. This version is updated to deal with dmapi aswell which greatly simplifies the get_dirattrs code. The dmapi part has been tested using the get_dirattrs tools from the xfstest dmapi suite1 with various small and large directories.
