Shamir seals now come in two varieties: legacy and new-style. (#7694)
Shamir seals now come in two varieties: legacy and new-style. Legacy
Shamir is automatically converted to new-style when a rekey operation
is performed. All new Vault initializations using Shamir are new-style.

New-style Shamir writes an encrypted master key to storage, just like
AutoUnseal. The stored master key is encrypted using the shared key that
is split via Shamir's algorithm. Thus when unsealing, we take the key
fragments given, combine them into a Key-Encryption-Key, and use that
to decrypt the master key on disk. Then the master key is used to read
the keyring that decrypts the barrier.

Fix a deadlock if a panic happens during request handling (#6920)
* Fix a deadlock if a panic happens during request handling

During request handling, if a panic is created, deferred functions are
run but otherwise execution stops. #5889 changed some locks to
non-defers but had the side effect of causing the read lock to not be
released if the request panicked. This fixes that and addresses a few
other potential places where things could go wrong:

1) In sealInitCommon we always now defer a function that unlocks the
read lock if it hasn't been unlocked already
2) In StepDown we defer the RUnlock but we also had two error cases that
were calling it manually. These are unlikely to be hit but if they were
I believe would cause a panic.

* Add panic recovery test

Allow plugins to submit audit requests/responses via extended SystemView (#6777)
Move audit.LogInput to sdk/logical.  Allow the Data values in audited
logical.Request and Response to implement OptMarshaler, in which case
we delegate hashing/serializing responsibility to them.  Add new
ClientCertificateSerialNumber audit request field.

SystemView can now be cast to ExtendedSystemView to expose the Auditor
interface, which allows submitting requests and responses to the audit
broker.

if a standby disconnects from an active node and reconnects, without the
active node restarting, the UUID doesn't change so triggers on a new
active node don't get run.

* Add a bunch of test helpers and minor updates to things.

Jeff Mitchell 9687ccc8fa Tackle #4929 a different way (#4932)
* Tackle #4929 a different way

This turns c.sealed into an atomic, which allows us to call sealInternal
without a lock. By doing so we can better control lock grabbing when a
condition causing the standby loop to get out of active happens. This
encapsulates that logic into two distinct pieces (although they could
be combined into one), and makes lock guarding more understandable.

* Re-add context canceling to the non-HA version of sealInternal

* Return explicitly after stopCh triggered

Changes the way policies are reported in audit logs (#4747)
* This changes the way policies are reported in audit logs.

Previously, only policies tied to tokens would be reported. This could
make it difficult to perform after-the-fact analysis based on both the
initial response entry and further requests. Now, the full set of
applicable policies from both the token and any derived policies from
Identity are reported.

To keep things consistent, token authentications now also return the
full set of policies in api.Secret.Auth responses, so this both makes it
easier for users to understand their actual full set, and it matches
what the audit logs now report.

Remove a lot of deferred functions in the request path. (#4733)
* Remove a lot of deferred functions in the request path.

There is an interesting benchmark at https://www.reddit.com/r/golang/comments/3h21nk/simple_micro_benchmark_to_measure_the_overhead_of/

It shows that defer actually adds quite a lot of overhead -- maybe 100ns
per call but we defer a *lot* of functions in the request path. So this
removes some of the ones in request handling, ha, barrier, router, and
physical cache.

One meta-note: nearly every metrics function is in a defer which means
every metrics call we add could add a non-trivial amount of time, e.g.
for every 10 extra metrics statements we add 1ms to a request. I don't
know how to solve this right now without doing what I did in some of
these cases and putting that call into a simple function call that then
goes before each return.

* Simplify barrier defer cleanup

Some atomic cleanup (#4732)
Taking inspiration from
https://github.com/golang/go/issues/17604#issuecomment-256384471
suggests that taking the address of a stack variable for use in atomics
works (at least, the race detector doesn't complain) but is doing it
wrong.

The only other change is a change in Leader() detecting if HA is enabled
to fast-path out. This value never changes after NewCore, so we don't
need to grab the read lock to check it.
