Handle chain server connection errors, if any
Make move and setaccount unsupported methods.

We no longer need to lie about supporting these in the future as they
will be impossible to implement correctly with the upcomming HD
wallet.
Remove plan9 rename function.

This function was misleading because it was actually *not* atomic
(meaning it should have never been used at all where atomicity was
required).  This will break builds on Plan 9 but I consider this fine
to do since the soon-to-be-integrated waddrmgr package relies on bolt
as a database and also does not compile for Plan 9.

This reverts commit 2a5e8587f65cac4780647d80b9e48e9695044b58.

Address a couple of nits with recent En(De)crypt.

This commit adds comments about the specific crypto key types, moves the
selectCryptoKey function before the Encrypt/Decrypt functions that call it
to be more consistent with the rest of the code base, and slightly
modifies the verbiage of the comment.
Add the new ErrInvalidKeyType to the stringer map.

Also add it to the stringer test.
