This is a followup to issue 6927044. I *really* don't want to
break streaming for large encrypted data packets.
Removing the automatic re-parsing. OpaqueReader can be
used for recovering useful information from mangled/unsupported packets.

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.
