This paves the way for making pick_first the universal leaf policy (see
#32692
An error occurred
), which will be needed for the dualstack design. That change will
require changing pick_first to see both the raw connectivity state and
the health-checking connectivity state of a subchannel, so that we can
enable health checking when pick_first is used underneath round_robin
without actually changing the pick_first connectivity logic (currently,
pick_first always disables health checking). To make it possible to do
that, this PR moves the health checking code out of the subchannel and
into a separate API using the same data-watcher mechanism that was added
for ORCA OOB calls.
The PR also creates a separate BUILD target for:
- chttp2 context list
- iomgr buffer_list
- iomgr internal errqueue
This would allow the context list to be included as standalone
dependencies for EventEngine implementations.

The very non-trivial upgrade of third_party/protobuf to 22.x
This PR strives to be as small as possible and many changes that were
compatible with protobuf 21.x and didn't have to be merged atomically
with the upgrade were already merged.
Due to the complexity of the upgrade, this PR wasn't created
automatically by a tool, but manually. Subsequent upgraded of
third_party/protobuf with our OSS release script should work again once
this change is merged.
This is best reviewed commit-by-commit, I tried to group changes in
logical areas.
Notable changes:
- the upgrade of third_party/protobuf submodule, the bazel protobuf
dependency itself
- upgrade of UPB dependency to 22.x (in the past, we used to always
upgrade upb to "main", but upb now has release branch as well). UPB
needs to be upgraded atomically with protobuf since there's a de-facto
circular dependency (new protobuf depends on new upb, which depends on
new protobuf for codegen).
- some protobuf and upb bazel rules are now aliases, so `
extract_metadata_from_bazel_xml.py` and `gen_upb_api_from_bazel_xml.py`
had to be modified to be able to follow aliases and reach the actual
aliased targets.
- some protobuf public headers were renamed, so especially
`src/compiler` needed to be updated to use the new headers.
- protobuf and upb now both depend on utf8_range project, so since we
bundle upb with grpc in some languages, we now have to bundle utf8_range
as well (hence changes in build for python, PHP, objC, cmake etc).
- protoc now depends on absl and utf8_range (previously protobuf had
absl dependency, but not for the codegen part), so python's
make_grpcio_tools.py required partial rewrite to be able to handle those
dependencies in the grpcio_tools build.
- many updates and fixes required for C++ distribtests (currently they
all pass, but we'll probably need to follow up, make protobuf's and
grpc's handling of dependencies more aligned and revisit the
distribtests)
- bunch of other changes mostly due to overhaul of protobuf's and upb's
internal build layout.
TODOs:
- [DONE] make sure IWYU and clang_tidy_code pass
- create a list of followups (e.g. work to reenable the few tests I had
to disable and to remove workaround I had to use)
- [DONE in cl/523706129] figure out problem(s) with internal import

Various fixes that can be merged in advance, to simplify the 22.x
upgrade.
- Use NOMINMAX for grpcio_tools build to avoid build failure when absl
is added as a dependency. Fixes
https://github.com/grpc/grpc/issues/32779
- in spawn_patch command file, put arguments on multiple lines to avoid
lines going over the limit for large link commands: Fixes
https://github.com/grpc/grpc/issues/32795
- Use `python/generator.h` instead of the deprecated
`python/python_generator.h` in grpcio_tools.
### Description
When invoking a RPC, sometimes operations in core will fail which result
in an `ExecuteBatchError`, currently we [simply raise this
error](https://github.com/grpc/grpc/blob/master/src/python/grpcio/grpc/_cython/_cygrpc/aio/server.pyx.pxi#L705),
and left this Exception unhandled in event loop with error message `Task
exception was never retrieved`.
### Changes included
This PR changes the behavior to log the `ExecuteBatchError` instead of
raising it.
This shouldn't change existing behavior because even without this
change, the exception will simply left on event loop.
### Testing
Tested by manually `set_expection` in [this
future](https://github.com/grpc/grpc/blob/master/src/python/grpcio/grpc/_cython/_cygrpc/aio/callback_common.pyx.pxi#L84),
verified that error was logged correctly and no exception was left in
event loop, sample log:
```

Fix python type hints for async iteration on `UnaryStreamCall` and
`StreamStreamCall`. Those classes _are_ `AsyncIterable`s and `__aiter__`
returns an `AsyncIterator`.

This PR also centralizes the client channel resolver selection. Resolver
selection is still done using the plugin system, but when the Ares and
native client channel resolvers go away, we can consider bootstrapping
this differently.

(hopefully last try)
Add new channel arg GRPC_ARG_ABSOLUTE_MAX_METADATA_SIZE as hard limit
for metadata. Change GRPC_ARG_MAX_METADATA_SIZE to be a soft limit.
Behavior is as follows:
Hard limit
(1) if hard limit is explicitly set, this will be used.
(2) if hard limit is not explicitly set, maximum of default and soft
limit * 1.25 (if soft limit is set) will be used.
Soft limit
(1) if soft limit is explicitly set, this will be used.
(2) if soft limit is not explicitly set, maximum of default and hard
limit * 0.8 (if hard limit is set) will be used.
Requests between soft and hard limit will be rejected randomly, requests
above hard limit will be rejected.

This is a big rewrite of global config.
It does a few things, all somewhat intertwined:
1. centralize the list of configuration we have to a yaml file that can
be parsed, and code generated from it
2. add an initialization and a reset stage so that config vars can be
centrally accessed very quickly without the need for caching them
3. makes the syntax more C++ like (less macros!)
4. (optionally) adds absl flags to the OSS build
This first round of changes is intended to keep the system where it is
without major changes. We pick up absl flags to match internal code and
remove one point of deviation - but importantly continue to read from
the environment variables. In doing so we don't force absl flags on our
customers - it's possible to configure grpc without the flags - but
instead allow users that do use absl flags to configure grpc using that
mechanism. Importantly this lets internal customers configure grpc the
same everywhere.
Future changes along this path will be two-fold:
1. Move documentation generation into the code generation step, so that
within the source of truth yaml file we can find all documentation and
data about a configuration knob - eliminating the chance of forgetting
to document something in all the right places.
2. Provide fuzzing over configurations. Currently most config variables
get stashed in static constants across the codebase. To fuzz over these
we'd need a way to reset those cached values between fuzzing rounds,
something that is terrifically difficult right now, but with these
changes should simply be a reset on `ConfigVars`.

Prior to this change, we invoke aycnio interceptors by converting them
to `iterator` first, which means we can only call them once before
they're exhausted.
This PR changes the implementation to use `list`, thus the interceptors
can be called multiple times.

This change mostly aims to get OpenCensus to use the new
ServerCallTracer interface. Note that the interfaces nor the code are in
their final states. There are a bunch of moving pieces, but I thought
this might be a nice mid-step to check-in and make sure that our
internal traces can also work with these changes.
Overall changes -
1) call_tracer.h shows what the hierarchy of new call tracer interfaces
looks like. Open to renaming suggestions.
2) Moved most of the common interface between `CallAttemptTracer` and
`ServerCallTracer` into a common `CallTracerInterface`. We should be
able to eventually move `RecordReceivedTrailingMetadata` and `RecordEnd`
as well to these common interfaces, but it requires some additional
work.
3) The compression filter is now responsible for recording the recv and
send messages for both the subchannel call and the server, and adds in
ability to record compressed and decompressed messages as well.
4) The OpenCensus server filter now uses the new `ServerCallTracer`
interface, and so doesn't need to be a filter anymore.
5) A new ServerCallTracerFilter was added. Ideally, we should be able to
move it to the current connected filter, but it is in a bit of an
interesting state right now, so I would prefer making those changes in a
separate PR with Craig's eyes on it.
6) A new context element `GRPC_CONTEXT_CALL_TRACER_ANNOTATION_INTERFACE`
was created that replaces the old `GRPC_CONTEXT_CALL_TRACER`, and the
new `GRPC_CONTEXT_CALL_TRACER` is mainly to pass the `CallAttemptTracer`
down the stack. This should go away in the new promise-based world.

It looks like nobody ever created ALTS redentials from Python with a
list of accepted service accounts before.
Simple reproduction:
```
import grpc
grpc.alts_channel_credentials(None) # works
grpc.alts_channel_credentials(['foo']) # fails
```
Without this change, generates this error:
```
[...]
File "src/python/grpcio/grpc/_cython/_cygrpc/credentials.pyx.pxi", line 414, in _cython.cygrpc.channel_credentials_alts
File "src/python/grpcio/grpc/_cython/_cygrpc/credentials.pyx.pxi", line 403, in _cython.cygrpc.ALTSChannelCredentials.__cinit__
TypeError: expected bytes, str found
```
(And the error cannot be worked around by the caller by passing a bytes
object from the Python side: you still get the same error.)
Upgrade boringssl to the latest "master-with-bazel"

Internal Windows builds will catch issues that we cannot yet catch in
OSS. This will be mostly remedied once we have clang-cl in our CI (See a
rough roadmap in https://github.com/grpc/grpc/pull/32448). For now, this
PR identifies folders where most Windows-specific code is developed, and
requires cherrypicks for PRs that touch anything inside those folders.
This PR also refactors gpr and gprpp source files to better isolate all
platform-specific code ~the Windows-only code~. ~I will reorganize the
other platform-specific files using this structure if there are no
objections.~
This subset of folders covers about half of the `#ifdef GPR_WINDOWS`
usages in gRPC, but nearly all of the actively-developed Windows code
locations.
This version broke backward compatibility in `plugin_pb2.py`, which is
presumably a relatively minor regression, since we have not yet heard
any complaints about it. This PR:
- Excludes `4.22.0` from installation
- _Includes_ protobuf pre-releases into testing so this can be caught
more quickly in the future.
When bad prereleases are caught, we can exclude them from testing in a
similar manner to this PR. We may eventually want to invest into a
system where we can define these bad versions centrally.
This code is not plumbed through yet, but it provides the core
infrastructure needed to detect the proper GCP environment resources
needed to set up the labels/attributes/resources for stats, tracing and
logging.
Details on how the various environment resources are setup has been
derived by looking at java's cloud logging library and OpenTelemetry's
future plans. (Could be better explained in an offline review since some
links are internal).
Requesting @veblush for a full review and @markdroth for a structural
review.
