xattr: define vfs_getxattr_alloc and vfs_xattr_cmp
vfs_getxattr_alloc() and vfs_xattr_cmp() are two new kernel xattr helper functions. vfs_getxattr_alloc() first allocates memory for the requested xattr and then retrieves it. vfs_xattr_cmp() compares a given value with the contents of an extended attribute.
