xfs: unify directory/attribute format definitions
The on-disk format definitions for the directory and attribute
structures are spread across 3 header files right now, only one of
which is dedicated to defining on-disk structures and their
manipulation (xfs_dir2_format.h). Pull all the format definitions
into a single header file - xfs_da_format.h - and switch all the
code over to point at that.

- * for the free bytes after the leaf_entry's, but only the N largest such,
- * smaller runs are dropped. When the freemap doesn't show enough space
- * for an allocation, we compact the name/value area and try again. If we

- * We store the fact that an attribute is a ROOT/USER/SECURE attribute in

+ * Attribute storage layout
+ *
+ * Attribute lists are structured around Btrees where all the data

+ * of an attribute name may not be unique, we may have duplicate keys. The

+ * Attribute structure when equal to XFS_LBSIZE(mp) bytes.
+ *========================================================================
+ *
+ * Struct leaf_entry's are packed from the top. Name/values grow from the
+ * bottom but are not packed. The freemap contains run-length-encoded entries
+ * for the free bytes after the leaf_entry's, but only the N largest such,
+ * smaller runs are dropped. When the freemap doesn't show enough space
+ * for an allocation, we compact the name/value area and try again. If we
+ * still don't have enough space, then we have to split the block. The
+ * name/value structs (both local and remote versions) must be 32bit aligned.
+ *
+ * Since we have duplicate hash keys, for each key that matches, compare
+ * the actual name string. The root and intermediate node search always
+ * takes the first-in-the-block key match found, so we should only have
+ * to work "forw"ard. If none matches, continue with the "forw"ard leaf
+ * nodes until the hash key changes or the attribute name is found.
+ *
+ * We store the fact that an attribute is a ROOT/USER/SECURE attribute in
+ * the leaf_entry. The namespaces are independent only because we also look
+ * at the namespace bit when we are looking for a matching attribute name.
+ *
+ * We also store an "incomplete" bit in the leaf_entry. It shows that an
+ * attribute is in the middle of being created and should not be shown to
+ * the user if we crash during the time that the bit is set. We clear the
+ * bit when we have finished setting up the attribute. We do this because
+ * we cannot create some large attributes inside a single transaction, and we
+ * need some indication that we weren't finished if we crash in the middle.
