When parsing a descriptor with `Descriptor::parse_descriptor`, we first parse as a string and then parse the keys. We fail to consider parsing errors in the keys, resulting in a panic. Also, clean up the panic message so it's clearer what's going on.

This is a direct rebase of #810 except that I added a commit with some lint fixes. (I had been avoiding this, but we've been having a lot of backports lately so I think I ought to just address it.) After this I will do 11.x.
