Loading an accumulated set of crlite stashes can take some time. To address
this, this patch dispatches an asynchronous background task to read the
accumulated set of crlite stashes in a way that doesn't block certificate
verification. Of course, this means that the stash information won't
necessarily be available for the first few verifications. This shouldn't be a
security concern as long as the crlite filter is no more than 10 days out of
date (the maximum lifespan of an OCSP response, which is what Firefox relies on
currently in release). Note that currently crlite filters as published by
remote settings regularly end up being more than 10 days old, which will be
addressed in https://github.com/mozilla/crlite/issues/153. Note further that
crlite is currently not being enforced by default on any channel, so making
this change now is not a security concern.

InitializeCipherSuite() in nsNSSComponent.cpp controls which encryption schemes
are allowed when decrypting PKCS12 files. Before this patch, the AES ciphers
were not enabled, which prevented importing PKCS12 files that used AES.
This patch fixes this and adds a test.

Bug 1690583 - Fix CH padding extension size calculation. r=mt
Bug 1654332 changed the way that NSS constructs Client Hello
messages. `ssl_CalculatePaddingExtLen` now receives a
`clientHelloLength` value that includes the 4B handshake header.
This looks okay per the inline comment (which states that only the
record header is omitted from the length), but the function actually
assumes that the handshake header is also omitted.
This patch removes the addition of the handshake header length.
Those bytes are already included in the buffered CH.

Bug 1689228 - Minor ECH -09 fixes for interop testing, fuzzing. r=mt
A few minor ECH -09 fixes for interop testing and fuzzing:
- selfserv now takes a PKCS8 keypair for ECH. This is more
maintainable and significantly less terrible than parsing the
ECHConfigs and cobbling one together within selfserv (e.g. we can
support other KEMs without modifying the server).
- Get rid of the newline character in tstclnt retry_configs output.
- Fuzzer fixes in tls13_HandleHrrCookie:
- We shouldn't use internal_error when PK11_HPKE_ImportContext fails.
Cookies are unprotected in fuzzer mode, so this can be expected to
occur.
- Only restore the application token when recovering hash state,
otherwise the copy could happen twice, leaking one of the
allocations.

See bug 1689728. To avoid contention on NSS resources and thread-safety issues,
this patch dispatches synchronous events to the socket thread in
NSSCertDBTrustDomain::GetCertTrust and FindIssuer to gather information from
NSS rather than using NSS directly on the cert verification threads.

This patch improves the performance of DER.jsm by changing readBytes to use
slice rather than repeatedly calling readByte.
Additionally, this patch removes the validation that the input to DERDecoder
consists of an array of integers in the range [0, 255]. This check is
unnecessary for all current consumers of DER.jsm because the input comes from
atob, which only outputs values in that range. If other consumers use DER.jsm
in the future, they will have to determine whether or not they need to validate
the input themselves first.

Bug 1678398 - Add Export/Import functions for HPKE context. r=mt
This patch adds and exports two new HPKE functions:
`PK11_HPKE_ExportContext` and `PK11_HPKE_ImportContext`, which are
used to export a serialized HPKE context, then later reimport that
context and resume Open and Export operations. Only receiver
contexts are currently supported for export (see the rationale in
pk11pub.h).
One other change introduced here is that `PK11_HPKE_GetEncapPubKey`
now works as expected on the receiver side.
If the `wrapKey` argument is provided to the Export/Import
functions, then the symmetric keys are wrapped with AES Key Wrap
with Padding (SP800-38F, 6.3) prior to serialization.

This patch updates ECH implementation to draft-09. Changes of note
are:
- Acceptance signal derivation is now based on the handshake secret.
- `config_id` hint changes from 32B to 8B, trial decryption added on
the server.
- Duplicate code in HRR cookie handling has been consolidated into
`tls13_HandleHrrCookie`.
- `ech_is_inner` extension is added, which causes a server to indicate
ECH acceptance.
- Per the above, support signaling ECH acceptance when acting as a
backend server in split-mode (i.e. when there is no other local
Encrypted Client Hello state).

Before this patch, nsIX509Cert.isSelfSigned was only used by LocalCertService
to verify that the certificate it uses is self-signed. This shouldn't have been
necessary, because the certificate isn't a trust anchor and an override has to
be added for it anyway. Additionally, the certificate in question is already
guaranteed to be self-signed because it was either just generated that way or
it was retrieved from the database (the code for which checks that it's
self-signed).
