This has been stable for a bit, everywhere that the EventEngine is
enabled. Going forward, I think the event_engine_{client|listener}
experiments can probably be used to regulate thread-pool-specific
issues.

I've added channel args to `CreateNewServerCallTracer` on the
`ServerCallTracerFactory`.
The motivation is for CSM Observability where the OTel plugin will be
configured to only do stats on servers which are xDS enabled, so I plan
to check this via channel args.
In the future, with the new scopes for metrics, I think I'll be able to
change this to only check once per server or server connection instead
of per call.

Most recent attempt was #34320, reverted in #34335.
The first commit here is a pure revert. The second commit fixes the
outlier_detection unit test to pass both with and without the
experiment.
This is a follow up to https://github.com/grpc/grpc/pull/34103
That pull request explicitly aimed to introduce shared library builds
for Windows (DLLs) while effecting zero material change to the existing
build pipelines. That aspiration meant that the grpc++_unsecure library
had to be effectively excluded from the build (because including it
would have also included a dependency on openssl, which makes no sense
given its purpose)
This PR addresses that by:
* Extracting the single function in grpc_tls_certificate_provider with a
dependency on openssl into a separate compilation unit
* Including that new .cc file into the grpc library
* Including grpc_tls_certificate_provider and one other source file into
grpc_unsecure for the Windows DLL build only.
* Reinstating the grpc++_unsecure library which is a prerequisite for
many tests.
* Regenerating all files affected by the changes in Bazel BUILD that
introduce the new source file.
This change does affect the operation of other build pipelines - I have
confirmed that it does not break the Linux Bazel build.

… c-ares versions (#34314)"

Tested by changing c-ares to `1.14.0` in Bazel dependency and verify
that the `posix_event_engine_test` build. The test would fail though
since c-ares versions < `1.16.0` does not come with address sorting
capability so the relevant test cases will fail. But this is probably
sufficient to make the Cloud C++ CI job pass and unblock the 1.58
release.

PanCakes to the rescue!
We noticed that our 'sanity' test was going to fail, but we think we can
fix that automatically, so we put together this PR to do just that!

Building out a new framing layer for chttp2.
The central idea here is to have the framing layer be solely responsible
for serialization of frames, and their deserialization - the framing
layer can reject frames that have invalid syntax - but the enacting of
what that frame means is left to a higher layer.
This class will become foundational for the promise conversion of chttp2
- by eliminating action from the parsing of frames we can reuse this
sensitive code.
Right now the new layer is inactive - there's a test that exercises it
relatively well, and not much more. In the next PRs I'll add an
experiments to enable using this layer or the existing code in the
writing and reading paths.

Proposed alternative to https://github.com/grpc/grpc/pull/34024.
This version has a simpler, faster busy-count implementation based on a
sharded set of atomic counts: fast increment/decrement operations,
relatively slower summation of total counts (which need to happen much
less frequently).
- Extract build metadata for some external dependencies from bazel
build. This is achieved by letting extract_metadata_from_bazel_xml.py
analyze some external libraries and sources. The logic is basically the
same as for internal libraries, I only needed to teach
extract_metadata_from_bazel_xml.py which external libraries it is
allowed to analyze.
* currently, the list of source files is automatically determined for
`z`, `upb`, `re2` and `gtest` dependencies (at least for the case where
we're building in "embedded" mode - e.g. mostly native extensions for
python, php, ruby etc. - cmake has the ability to replace some of these
dependencies by actual cmake dependency.)
- Eliminate the need for manually written gen_build_yaml.py for some
dependencies.
- Make the info on target dependencies in build_autogenerated.yaml more
accurate and complete. Until now, there were some depdendencies that
were allowed to show up in build_autogenerated.yaml and some that were
being skipped. This made generating the CMakeLists.txt and Makefile
quite confusing (since some dependencies are being explicitly mentioned
and some had to be assumed by the build system).
- Overhaul the Makefile
* the Makefile is currently only used internally (e.g. for ruby and PHP
builds)
* until now, the makefile wasn't really using the info about which
targets depend on what libraries, but it was effectively hardcoding the
depedendency data (by magically "knowing" what is the list of all the
stuff that e.g. "grpc" depends on).
* After the overhaul, the Makefile.template now actually looks at the
library dependencies and uses them when generating the makefile. This
gives a more correct and easier to maintain makefile.
* since csharp is no longer on the master branch, remove all mentions of
"csharp" targets in the Makefile.
Other notable changes:
- make extract_metadata_from_bazel_xml.py capable of resolving workspace
bind() rules (so that it knows the real name of the target that is
referred to as e.g. `//external:xyz`)
TODO:
- [DONE] ~~pkgconfig C++ distribtest~~
- [DONE} ~~update third_party/README to reflect changes in how some deps
get updated now.~~
Planned followups:
- cleanup naming of some targets in build metadata and buildsystem
templates: libssl vs boringssl, ares vs cares etc.
- further cleanup of Makefile
- further cleanup of CMakeLists.txt
- remote the need from manually hardcoding extra metadata for targets in
build_autogenerated.yaml. Either add logic that determines the
properties of targets automatically, or use metadata from bazel BUILD.
Our current implementation of Join, TryJoin leverage some complicated
template stuff to work, which makes them hard to maintain. I've been
thinking about ways to simplify that for some time and had something
like this in mind - using a code generator that's at least a little more
understandable to code generate most of the complexity into a file that
is checkable.
Concurrently - I have a cool optimization in mind - but it requires that
we can move promises after polling, which is a contract change. I'm
going to work through the set of primitives we have in the coming weeks
and change that contract to enable the optimization.

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.)

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)_/¯.

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)
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
Normally, c-ares related fds are destroyed after all DNS resolution is
finished in [this code
path](c82d31677a/src/core/ext/filters/client_channel/resolver/dns/c_ares/grpc_ares_wrapper.cc (L210)).
Also there are some fds that c-ares may fail to open or write to
initially, and c-ares will close them internally before grpc ever knows
about them.
But if:
1) c-ares opens a socket and successfully writes a request on it
2) then a subsequent read fails
Then c-ares will close the fd in [this code
path](bad62225b7/src/lib/ares_process.c (L740)),
but gRPC will have a reference on the fd and will still use it
afterwards.
Fix here is to leverage the c-ares socket-override API to properly track
fd ownership between c-ares and grpc.

- Make `Value` a simple wrapper around `Pointer` and use some blessed
vtables to distinguish strings vs ints vs actual pointers - this saves 8
bytes per value stored
- introduce `RcString` as a lightweight container around an immutable
string - this saves some bytes vs the shared_ptr<std::string> approach
we previously had, and importantly opens up the technique (via
`RcStringValue`) to channel node keys also, which should increase
sharing and consequently also decrease total memory usage
