Initial draft xattr support
Initial, incomplete, support for extended attributes. Extended attributes are implemented fairly naively, using a second table in the file database using the primary file table's id as a foreign key. The ON DELETE CASCADE behavior requires sqlite 3.6.19 or later with foreign key and trigger support compiled in. To reduce round-trips, the client does not check for existing attributes, but rather, sends three distinct set messages; OP_SET_XATTR, OP_CREATE_XATTR, OP_REPLACE_XATTR. A SET message always succeeds, a CREATE fails if the attribute already exists, and a REPLACE fails if the attribute does not already exist. The /* flags */ feature of makewrappers is used to correct path names appropriately, so all functions are already working with complete paths, and can always use functions that work on links; if they were supposed to dereference, the path fixup code got that. The xattr support is enabled, for now, conditional on whether getfattr --help succeeds. Not yet implemented: Translation for system.posix_acl_access, which is used by "cp -a" (or "cp --preserve-all") on some systems to try to copy modes.
