openpgp: improve parser resilience & flexibility, add PublicKey.BitLength()

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.
