certutil.ParseHexFormatted fails parsing 80 hex and above (#18018)
- Switch to using ParseUint of 8 bits to parse the hex values properly
   as ParseInt limited to 8 bits will only handle values up to 127
   decimal or 7F.

Add mount path into the default generated openapi.json spec (#17839)
The current behaviour is to only add mount paths into the generated `opeanpi.json` spec if a `generic_mount_paths` flag is added to the request. This means that we would have to maintain two different `openapi.json` files, which is not ideal. The new solution in this PR is to add `{mount_path}` into every path with a default value specified:

```diff
--    "/auth/token/accessors/": {
++    "/auth/{mount_path}/accessors/": {
      "parameters": [
        {
          "name": "mount_path",
          "description": "....",
          "in": "path",
          "schema": {
            "type": "string",
++          "default": "token"
          }
        }
      ],
```

Additionally, fixed the logic to generate the `operationId` (used to generate method names in the code generated from OpenAPI spec). It had a bug where the ID had `mountPath` in it. The new ID will look like this:

```diff
-- "operationId": "listAuthMountpathAccessors",
++ "operationId": "listTokenAccessors",
```

Add support for PKCSv1_5_NoOID signatures (#17636)
* Add support for PKCSv1_5_NoOID signatures

This assumes a pre-hashed input has been provided to Vault, but we do
not write the hash's OID into the signature stream. This allows us to
generate the alternative PKCSv1_5_NoOID signature type rather than the
existing PKCSv1_5_DERnull signature type we presently use.

These are specified in RFC 3447 Section 9.2.

Add AD mode to Transit's AEAD ciphers (#17638)
* Allow passing AssociatedData factories in keysutil

This allows the high-level, algorithm-agnostic Encrypt/Decrypt with
Factory to pass in AssociatedData, and potentially take multiple
factories (to allow KMS keys to work). On AEAD ciphers with a relevant
factory, an AssociatedData factory will be used to populate the
AdditionalData field of the SymmetricOpts struct, using it in the AEAD
Seal process.

* Add associated_data to Transit Encrypt/Decrypt API

This allows passing the associated_data (the last AD in AEAD) to
Transit's encrypt/decrypt when using an AEAD cipher (currently
aes128-gcm96, aes256-gcm96, and chacha20-poly1305). We err if this
parameter is passed on non-AEAD ciphers presently.

This associated data can be safely transited in plaintext, without risk
of modifications. In the event of tampering with either the ciphertext
or the associated data, decryption will fail.

Fix for duplicate SANs in signed certificates (#16700)
* Fix for duplicate SANs in signed certificates when othernames are present in the CSR SAN extension and UseCSRValues is true.

When UseCSRValues is true (as is the case on the sign-verbatim endpoint), all extensions including Subject Alternative Names are copied from the CSR to the final certificate.
If the Subject Alternative Name in question contains any othernames (such as a Microsoft UPN) the SAN extension is added again as a workaround for an encoding issue (in function HandleOtherSANs).
Having duplicate x509v3 extensions is invalid and is rejected by openssl on Ubuntu 20.04, and also by Go since https://github.com/golang/go/issues/50988 (including in Go 1.19).

In this fix I do not add the extension from the CSR if it will be added during HandleOtherSANs.

* Added unittest and changelog entry.

Fix RevocationSigAlg provisioning in GCP (#17449)
* Fix RevocationSigAlg provisioning in GCP

GCP restricts keys to a certain type of signature, including hash
algorithm, so we must provision our RevocationSigAlg from the root
itself unconditionally in order for GCP to work.

This does change the default, but only for newly created certificates.

Additionally, we clarify that CRL building is not fatal to the import
process.

PKI: Add support for signature_bits param to the intermediate/generate api (#17388)
* PKI: Add support for signature_bits param to the intermediate/generate api

 - Mainly to work properly with GCP backed managed keys, we need to
   issue signatures that would match the GCP key algorithm.
 - At this time due to https://github.com/golang/go/issues/45990 we
   can't issue PSS signed CSRs, as the libraries in Go always request
   a PKCS1v15.
 - Add an extra check in intermediate/generate that validates the CSR's
   signature before providing it back to the client in case we generated
   a bad signature such as if an end-user used a GCP backed managed key
   with a RSA PSS algorithm.
   - GCP ignores the requested signature type and always signs with the
     key's algorithm which can lead to a CSR that says it is signed with
     a PKCS1v15 algorithm but is actually a RSA PSS signature

Check if plugin version matches running version (#17182)
Check if plugin version matches running version

When registering a plugin, we check if the request version matches the
self-reported version from the plugin. If these do not match, we log a
warning.

This uncovered a few missing pieces for getting the database version
code fully working.

We added an environment variable that helps us unit test the running
version behavior as well, but only for approle, postgresql, and consul
plugins.

Return 400 on plugin not found or version mismatch

Add plugin version to GRPC interface (#17088)
Add plugin version to GRPC interface

Added a version interface in the sdk/logical so that it can be shared between all plugin types, and then wired it up to RunningVersion in the mounts, auth list, and database systems.

I've tested that this works with auth, database, and secrets plugin types, with the following logic to populate RunningVersion:

If a plugin has a PluginVersion() method implemented, then that is used
If not, and the plugin is built into the Vault binary, then the go.mod version is used
Otherwise, the it will be the empty string.
My apologies for the length of this PR.

* Placeholder backend should be external

We use a placeholder backend (previously a framework.Backend) before a
GRPC plugin is lazy-loaded. This makes us later think the plugin is a
builtin plugin.

So we added a `placeholderBackend` type that overrides the
`IsExternal()` method so that later we know that the plugin is external,
and don't give it a default builtin version.

Support for generating Delta CRLs (#16773)
* Allow generation of up-to-date delta CRLs

While switching to periodic rebuilds of CRLs alleviates the constant
rebuild pressure on Vault during times of high revocation, the CRL
proper becomes stale. One response to this is to switch to OCSP, but not
every system has support for this. Additionally, OCSP usually requires
connectivity and isn't used to augment a pre-distributed CRL (and is
instead used independently).

By generating delta CRLs containing only new revocations, an existing
CRL can be supplemented with newer revocations without requiring Vault
to rebuild all complete CRLs. Admins can periodically fetch the delta
CRL and add it to the existing CRL and applications should be able to
support using serials from both.

Because delta CRLs are emptied when the next complete CRL is rebuilt, it
is important that applications fetch the delta CRL and correlate it to
their complete CRL; if their complete CRL is older than the delta CRL's
extension number, applications MUST fetch the newer complete CRL to
ensure they have a correct combination.

This modifies the revocation process and adds several new configuration
options, controlling whether Delta CRLs are enabled and when we'll
rebuild it.

Add proof possession revocation for PKI secrets engine (#16566)
* Allow Proof of Possession based revocation

Revocation by proof of possession ensures that we have a private key
matching the (provided or stored) certificate. This allows callers to
revoke certificate they own (as proven by holding the corresponding
private key), without having an admin create innumerable ACLs around
the serial_number parameter for every issuance/user.

We base this on Go TLS stack's verification of certificate<->key
matching, but extend it where applicable to ensure curves match, the
private key is indeed valid, and has the same structure as the
corresponding public key from the certificate.

This endpoint currently is authenticated, allowing operators to disable
the endpoint if it isn't desirable to use, via ACL policies.

* Leave revoke-with-key authenticated

After some discussion, given the potential for DoS (via submitting a lot
of keys/certs to validate, including invalid pairs), it seems best to
leave this as an authenticated endpoint. Presently in Vault, there's no
way to have an authenticated-but-unauthorized path (i.e., one which
bypasses ACL controls), so it is recommended (but not enforced) to make
this endpoint generally available by permissive ACL policies.
