The original pipe implementation made a few assumptions:
* it should be used outside of arenas, implying allocation was expensive
* pipes would be fairly deep
With our expected implementation of the filter stack, pipes will max out at one to three stages, and so optimizations enabled by Filter seem to be actual pessimizations for our usual case.
Additionally we'll be operating inside of arenas and consequently memory allocation can be trivially cheap - and in doing so we can enable a far simpler implementation.

* Reintroduce the EventEngine default factory
An application can provide an EventEngine factory function that allows
gRPC internals to create EventEngines as needed. This factory would be
used when no EventEngine is provided for some given channel or server,
and where an EventEngine otherwise could not be provided by the
application. Note that there currently is no API to provide an
EventEngine per channel or per server.
I've also deleted some previous iterations on global EventEngine and
EventEngine factory ideas. This new code lives in a public API, and
coexists with iomgr instead of being isolated to an EventEngine-specific
iomgr implementation.
* add proper namespaces, and fix description
* put factory functions in their own file (for replaceability)
* add synchronization
* generate_projects.sh
* extract event_engine_base and event_engine_factory targets
Also separate iomgr/event_engine files in the BUILD, with comments
* gpr_platform
* move all EE factory declarations to event_engine_base
Makes internal hackery easier.
* add missing deps
* reorder dep alphabetically
* comment style change
* [BinderTransport] Avoid depending on NdkBinder at compile time
We would like to make it possible to use BinderTransport in a APK that
has min sdk version lower than 29 (NdkBinder was introduced at 29)
We copies constants and type definitions from Ndk headers, creates a
same name wrapper for every NdkBinder API we use in
grpc_binder::ndk_util namespace.
We will try to load libbinder_ndk.so and resolve the symbol when the
NdkBinder API wrappers are invoked.
* regenerate projects
* Add GRPC_NO_BINDER guard
A config option is provided so user can pass --define=grpc_no_binder=true to bazel, or passing `-DGRPC_NO_BINDER` to compiler to disable the dependency.
* Expose experimental binder transport API
New headers are added
`grpcpp/create_channel_binder.h `: interfaces for creating client
channel
`grpcpp/security/binder_credentials.h`: interfaces for binder server
credentials
`grpcpp/security/binder_security_policy.h`: interfaces for binder
security policy, which is used by both server and client. Individual
security policies are merged into this single header.
Users can now depend on the `grpc++_binder` target to use the headers
listed above.
* Regenerate projects
* [BinderTransport] Create client channel instead of direct channel
In this commit we create a client channel instead of direct channel.
BinderConnector is added to connect subchannel when the user actually
make RPC call using the channel.
BindToOnDeviceServerService() is not required anymore since now the
actual connection is delay until the channel is used.
* Regenerate projects.
* Add a class for generating readable connection id for binder
This class will be used to generate a connection IDs that are used to
identify binder transport connections. For now we have not migrated to
client channel yet so we simply use this new class to generate a
connection id for the only connection we support.
* Regenerate projects.
* ChannelStackModifier class
* Regenerate projects
* clang-tidy
* Use CoreConfiguration for inserting xDS HTTP filters
* New lines
* Move test to test/core/xds
* Add comment for placement of filter stack
* Fix sanity
* Fix memory leak - destroy builder
* Don't build xds_channel_stack_modifier_test on non-bazel build systems due to census dependency
This commit is part of the effort to create binder channel with
GRPC_CLIENT_CHANNEL type.
The resolver will be used during name resolution, and the result will
later be used to identify the corresponding endpoint binder in
SubchannelConnector.
Besides the unit test, this change is tested with other changes locally
end to end on real device.
