9021153e89 internal/eventlog: add code for parsing secure boot variables 
This is being prototyped in an internal package as we start to open
source. This code will either live in attest, or in a separate eventlog
package in the future.

e688ff6d7f attest: rename MintAIK and MintOptions to NewAIK and AIKConfig 
This helps the godoc read better and is more inline with Go's naming
scheme. No functional changes made, just naming.

9b6caf1273 attest: use provided randomness source when generating challenges (#80) 
Currently the activation challenge lets a caller supply a source of
randomness other than crypto/rand, but it's not used in some places.
Plumb the source through the call chain.

262599a8df attest: add event log parsing logic 
This PR adds event log parsing logic. It's main goal is to require
validation at the same time as parsing, so structured events are always
verified against a quote. This new API replaces the exisitng "verifier"
package.

It's not a goal of this PR to parse the event data. This will be a
follow up, but since different users might want to parse different
events based on the OS, this API lets users of this package implement
custom event data parsing if they absolutely need to.

7d7676beda attest: move public key parsing server side 
Event log parsing requires knowning both the public key and signing
parameters. Symmantically, this information should be from an attested
public key blob, not additional data passed by the client.

Introduce a new method for parsing an AIK's public key blob, returning
a new AIKPublic struct.

833a7e119f attest: remove unused KeyPurpose exported type 
Was going through the godoc and it's not clear that this is ever used.
To clean up the API, remove KeyPurpose for now. This could probably be
an internal validation anyway, right?

2464131d7c Add a Public() method to the AIK that returns a public key (#55) 
We plan to identify AIKs based on their public key. The raw blob should
be available via the AttestationParameters, but we hope that users will
only use that struct for generating challenges.

Because this parses the public key on AIK creation and loading, this PR
should have existing coverage.
