This change moves a number of common PKIX structures into
crypto/x509/pkix, from where x509, and ocsp can reference
them, saving duplication. It also removes x509/crl and merges it into
x509 and x509/pkix.
x509 is changed to take advantage of the big.Int support that now
exists in asn1. Because of this, the public/private key pair in
http/httptest/server.go had to be updated because it was serialised
with an old version of the code that didn't zero pad ASN.1 INTEGERs.

This mostly adds the infrastructure for writing various forms of
packets as well as reading them. Adding symmetric encryption support
was simply an easy motivation.
There's also one brown-paper-bag fix in here. Previously I had the
conditional for the MDC hash check backwards: the code was checking
that the hash was *incorrect*. This was neatly counteracted by another
bug: it was hashing the ciphertext of the OCFB prefix, not the
plaintext.

I ran the new verification code against a large number of certificates
with a huge (>1000) number of intermediates.
I had previously convinced myself that a cycle in the certificate
graph implied a cycle in the hash graph (and thus, a contradiction).
This is bogus because the signatures don't cover each other.
Secondly, I managed to drive the verification into a time explosion
with a fully connected graph of certificates. The code would try to
walk the factorial number of paths.
This change switches the CertPool to dealing with indexes of
certificates rather than pointers: this makes equality easy. (I didn't
want to compare pointers because a reasonable gc could move objects
around over time.)
Secondly, verification now memorizes the chains from a given
certificate. This is dynamic programming for the lazy, but there's a
solid reason behind it: dynamic programming would ignore the Issuer
hints that we can exploit by walking up the chain rather than down.

With full multi-prime support we can support version 1 PKCS#1 private
keys. This means exporting all the members of rsa.PrivateKey, thus
making the API a little messy. However there has already been another
request to export this so it seems to be something that's needed.
Over time, rsa.GenerateMultiPrimeKey will replace rsa.GenerateKey, but
I need to work on the prime balance first because we're no longer
generating primes which are a multiples of 8 bits.
Fixes#987.

Many recently issued certificates are chained: there's one or more

The crypto package is added as a common place to store identifiers for
hash functions. At the moment, the rsa package has an enumeration of
hash functions and knowledge of their digest lengths. This is an
unfortunate coupling and other high level crypto packages tend to need
to duplicate this enumeration and knowledge (i.e. openpgp).
crypto pulls this code out into a common location.
It would also make sense to add similar support for ciphers to crypto,
but the problem there isn't as acute that isn't done in this change.

error is needed by all the OpenPGP packages as they return a shared
family of error types.
armor implements OpenPGP armoring. It's very like PEM except:
a) it includes a CRC24 checksum
b) PEM values are small (a few KB) and so encoding/pem assumes that
they fit in memory. Armored data can be very large and so this
package presents a streaming interface.
