*: xattr can Update() This is a gnarly patchset that has been mashed together. It uncovered that some aspects of Check were never really working correctly for `xattr` keywords, but also the `Update()` had been left undone for a while. This includes some API changes around the `Keyword` and `KeyVal` types. Also I would like to update the signature for the `UpdateKeywordFunc` to just accept a `KeyVal` as an argugment, rather than a keyword AND the value. with this context there would be no need to guess on the value of what's passed to the xattr update function of whether it needs or already is base64 encoded.

*: update `-u` behavior Fixes #16 In attempt to close https://github.com/vbatts/go-mtree/issues/16 I've uncovered that the update was missing a function for symlink. Additionally the update was not even opperating on the correct directory hierarchy. I've uncovered that os.Chtimes follows the symlink, and presumably only Linux has an obscure way to set the mtime/atime on a symlink itself. So I've made a custom lchtimes(). Also Mode follows through the symlink, and symlinks only ever have a mode of 0777, so don't set them. Lastly, directories need to have their mtime/atime set in a reverse order after all other updates have been done. This is going to require something like a `container/heap` to be unwound. Also, each updateFunc will _only_ perform the update if it is needed. Much less invasive this way. Signed-off-by: Vincent Batts <vbatts@hashbangbash.com> 2017-06-26 19:12:31 +00:00			`import (`
