It looks like we're seeing a rare crash in the TCP read code, around
buffering for the next read. Unclear as yet whether this is due to
`memory_pressure_controller` rollout or not - see b/294609692,
b/294854129.
This change just adds some safety checks to try and ensure we never get
into the bad state - but it's unclear to me as yet how we do reach that
state.
This clearly indicates which errors are "blanket" errors and are not a
root cause on their own.
This also moves the debug info with the last known status of an object
the framework was waiting for, but bailed out due to a timeout.
Previously it was printed as the last error message in the test, and
this PR prints it after the stack trace that caused the test failure.
In addition, I added a similar debug information to the "wait for NEGs
to become healthy". Now it prints the statuses of unhealthy backends
To achieve that, I mimicked upcoming [PEP
678](https://peps.python.org/pep-0678/) Exception notes feature. When
we're upgrade to py11, we'll be able to remove `add_note()` methods, and
get the same functionality for free.

This PR adds in delegating call tracers that work like so -
If this is the first call tracer that is being added onto the call
context, just add it as earlier.
If this is the second call tracer that is being added onto the call
context, create a delegating call tracer that contains a list of call
tracers (including the first call tracer).
Any more call tracers added, just get added to the list of tracers in
the delegating call tracer.
(This is not yet used other than through tests.)

This doesn't matter for gtest (it does its own sorting later), but for
the fuzzers this will probably save a bit of churn in the corpus and
lead to faster discovery of interesting cases.
And add some trace points. This does not solve
[go/event-engine-forkable-prefork-deadlock](http://go/event-engine-forkable-prefork-deadlock),
but is a necessary step.
So ¯\\_(ツ)_/¯.

I'm fairly certain that this path should be non-blocking (and making it
so makes the promise based code far more tractable).
This moves the blocking behavior into the blocking server_cc.cc function
that calls `grpc_server_shutdown_and_notify` instead of in that
non-blocking function.

There's *very* little difference in cost for a pooled arena allocation
and a tcmalloc allocation - but the pooled allocation causes memory
stranding for call lifetime, whereas the tcmalloc allocation allows that
to be shared between calls - leading to a much lower overall cost.

~~NB: I haven't tested this at all and am hoping the CI will tell me
where I've (undoubtedly) messed something up.~~ Edit: looks like CI is
now clear!
BoringSSL's gas-compatible assembly files, like its C files, are now
wrapped with preprocessor ifdefs to capture which platforms each file
should be enabled on. This means that, provided the platform can process
.S files it all (i.e. not Windows), we no longer need to detect the
exact CPU architecture in the build.
Switch gRPC's build to take advantage of this. I've retained
BUILD_OVERRIDE_BORING_SSL_ASM_PLATFORM, on the off chance anyone is
using it to cross-compile between Windows and non-Windows, though I
doubt that works particularly well.
As part of this, restore assembly optimizations in a few places where
they were seemingly disabled for issues relating to this:
- https://github.com/grpc/grpc/pull/31747 had to disable the assembly,
because at the time assembly required the library be built differently
for each architecture and then stitched back together. This should now
work.
- tools/run_tests/run_tests.py disabled x86 assembly due to some issues
with CMAKE_SYSTEM_PROCESSOR in a Docker image. This too should now be
moot.

Add "bazelified" non-bazel tests. See tools/bazelify_tests/README.md for
the core idea.
- add a bunch of test targets that run under docker and execute tests
that correspond to `run_tests.py -l LANG ...`
- many more tests can be added in the future
- to enable running some of the C/C++ portability tests easily, added
support for `--cmake_extra_configure_args` in run_tests.py (the change
is fairly small).
Example passing build that shows how test results are structured:
https://source.cloud.google.com/results/invocations/21295351-a3e3-4be1-b6e9-aaf52195a044/targets
The previous version (`3.12`) is 7 years old and does not support the
newest Python 3 versions. This causes issues to move certain test
targets (which depends on `pyyaml`) to Python 3 when some CI environment
(e.g. `arm64v8/debian:11`) does not have Python 2 installed. And in
general, we should move away from Python 2. Thus, updated `pyyaml` to
the latest version.
This hopefully should also fix the
`prod:grpc/core/master/linux/arm64/grpc_bazel_test_c_cpp` job breakage.

Rolls forward https://github.com/grpc/grpc/pull/33871
Second and third commits here fix internal build issues
In particular, add a `// IWYU pragma: no_include <ares_build.h>` since
`ares.h` [includes that
anyways](bad62225b7/include/ares.h (L23))
(and seems unlikely for that to change since it would be breaking)
This enables both of the `event_engine_listener` and `work_stealing`
experiments together, which we expect will have better performance. The
benchmark-config-generation script required some light modification to
support running multiple experiments at the same time.
Implement DNS using dns service for iOS.
Current limitation:
1. Using a custom name server is not supported.
2. Only supports `LookupHostname`. `LookupSRV` and `LookupTXT` are not
implemented.
3. Not tested with single stack (ipv4 or ipv6) environment
4. ~Not tested with multiple ip records per stack~ manually tested with
wsj.com
5. Not tested with multiple interface environment
Need the ability to override server-side keepalive permit without calls
default without affecting client-side settings.
