* The main driver for this change was to make the read from a.newFragmentCh timeout quickly rather than waiting for the test timeout (much longer). While testing the change I observed a panic during shutdown, but it was swallowed and moreover there was no stack trace so it wasn't obvious. I'm hoping we can get rid of the recover, so I fixed the issue in the activitylog tests that needed it.

Go 1.13 flipped TLS 1.3 to opt-out instead of opt-in, and its TLS 1.3
support does not allow configuring cipher suites. Simply remove the
affected test; it's not relevant going forward and there's ample
evidence it works properly prior to Go 1.13.
* Handpick cluster cipher suites when they're not user-set
There is an undocumented way for users to choose cluster cipher suites
but for the most part this is to paper over the fact that there are
undesirable suites in TLS 1.2.
If not explicitly set, have the set of cipher suites for the cluster
port come from a hand-picked list; either the allowed TLS 1.3 set (for
forwards compatibility) or the three identical ones for TLS 1.2.
The 1.2 suites have been supported in Go until at least as far back as
Go 1.9 from two years ago. As a result in cases where no specific suites
have been chosen this _ought_ to have no compatibility issues.
Also includes a useful test script.
* Abstract generate-root authentication into the strategy interface
* Generate root strategy ncabatoff (#7700)
* Adapt to new shamir-as-kek reality.
* Don't try to verify the master key when we might still be sealed (in
recovery mode). Instead, verify it in the authenticate methods.
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.
* core: add postSealMigration method
The postSealMigration method is called at the end of the postUnseal
method if a seal migration has occurred. This starts a seal rewrap
process in the enterprise version of. It is a no-op in the OSS version.
* Initial work
* rework
* s/dr/recovery
* Add sys/raw support to recovery mode (#7577)
* Factor the raw paths out so they can be run with a SystemBackend.
# Conflicts:
# vault/logical_system.go
* Add handleLogicalRecovery which is like handleLogical but is only
sufficient for use with the sys-raw endpoint in recovery mode. No
authentication is done yet.
* Integrate with recovery-mode. We now handle unauthenticated sys/raw
requests, albeit on path v1/raw instead v1/sys/raw.
* Use sys/raw instead raw during recovery.
* Don't bother persisting the recovery token. Authenticate sys/raw
requests with it.

* Accept only one seal config in recovery mode as there is no scope for migration
Seal keys can be rotated. When this happens, the barrier and recovery
keys should be re-encrypted with the new seal key. This change
automatically re-encrypts the barrier and recovery keys with the latest
seal key on the active node during the 'postUnseal' phase.

At the level of role config it doesn't mean anything to use
default-service or default-batch; that's for mount tuning. So disallow
it in tokenutil. This also fixes the fact that the switch statement
wasn't right.

* 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
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.
