Casey Marshall 964142eb52 openpgp/packet: Add support for V3 public keys and signatures.
My goal here is to allow read-only access to legacy key material without allowing new V3 keys or signatures.

Casey Marshall 3780a70b7b go.crypto/openpgp/packet: Add user attribute packet support.
Supports JPEG images as well as free-form arbitrary subpacket data in
user attributes (RFC 4880, Section 5.12)

Brian Gitonga Marete 690e22b80a openpgp: Implement compressed data packets & add support for compressing data during symmetric encryption.
This patch implements the facilities needed to compress data before
encryption as allowed (and recommended) by RFC 4880. The new
functionality is then used to add support for compressing data during
symmetric encryption (openpgp.SymmetricallyEncrypt()).

For now, compression defaults to off. Also, only the ZIP and ZLIB
compression schemes are supported by this patch.

Resulting output tested/verified using GPG.

https://gist.github.com/marete/6189760 is a small program that can be
used to test that the output of various compression/encryption settings
can be read by GPG or other RFC 4880 programs.

Upon review, I will follow this patch with 2 others: a) Add support for 	compression during public key encryption (openpgp.Encrypt()) b) Enable
compression by default (subject to the restrictions of the "Compression 	Preferences" section in RFC 4880).

Adam Langley aa0f5b4081 go.crypto: revert 7f5a59ff6b43.
This change reverts https://golang.org/cl/10113043/ because
some folks are stuck on 1.0 till 1.1.1 comes out.

Adam Langley eca6c1626e go.crypto: remove unreachable code.
I ran go vet over all of go.crypto and removed lots of panic("unreachable") that are no longer needed.

Casey Marshall 50ff460fe1 openpgp: remove TeeReader from packet.Read
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.

Casey Marshall 2da167fbbe 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.

Adam Langley be3c8d448b openpgp: support 3DES encrypted private keys.
It appears that CentOS (and so I presume Fedora/RHEL too) default to
encrypting private keys with 3DES so it looks like we need to support
that.

Fixes golang/go#3940.
