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).

compiled in then it would panic.

Paul van Brouwershaven pointed out that it would be better to pass in
the issuing certificate and have the verification be done in the OCSP
package than to expect the caller to deal with the difference between
responses with and without a responder certificate.

Some OCSP responses (notably COMODO's) don't use an intermediate
certificate to sign OCSP responses so this change allowed that.
Additionally, a CreateRequest function is added for creating OCSP
requests.
This change makes one API change: SerialNumber becomes a *big.Int to
match crypto/x509. The original code dates to before encoding/asn1
could cope with big.Ints and using a []byte was a workaround for that.

change avoids altering the globals since the default worked anyway.

The session test previously had a one second timeout for the output of
stty and this was leading to flakiness. This change removes the timeout
since go test has a generic timeout mechanism.
Additionally, the test was looking for "-echo" in the output to test
the value of the echo flag. However, there are also typically "echoe",
"echok" and "echonl" flags, and "-echo" could be a prefix of any of
time. Thus we now also match a trailing space.

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.
