MPIs are (supposed to be) stripped of leading zeroes. Avoid passing
such short values into crypto/rsa, even if it currently happens to work.

Rather than rounding the `type || X || Y` byte sequence to the next
8-bit boundary, packet.NewECDSAPublicKey() now rounds the X and Y
coordinates individually, then adds the bitlength 3 of type 4
(compressed). For NIST P-256, this leads to a bit length of 515,
rather than 520. GnuPG calculates 515 as well, and
https://tools.ietf.org/html/rfc6637#section-6 explicitly states that
"the exact size of the MPI payload is 515 bits for 'Curve P-256,'"
so the new formula is consistent.

When writing keys that contain ElGamal subkeys, the openpgp
package would previously return an error.

Entity.SignIdentity used the wrong signature function and produced invalid
certification signatures. Fixed.
VerifyUserIdSignature was used for checking the self-signature on an identity,
but didn't support anything but a self-signature. This change alters the
low-level API so that checking cross-signatures is possible.
Fixesgolang/go#7371.

My goal here is to allow read-only access to legacy key material without allowing new V3 keys or signatures.

I ran go vet over all of go.crypto and removed lots of panic("unreachable") that are no longer needed.

These are improvements I've made as necessary to develop Hockeypuck,
an OpenPGP keyserver (https://launchpad.net/hockeypuck).
The max armor line length was increased to 96 because some keyservers (SKS)
will output armor with lines greater than 64 (the prior max).
I've exposed packet.ReadEntity to support stream-parsing, useful for
large SKS dump files.
ReadKeyRing attempts to recover in the event of malformed data.
Because many packet types are not yet supported, I added OpaquePacket to
capture unsupported types for offline storage and later reparsing.
