This is to use `grpc_core::RefCount` to improve performnace.
This commit also replaces explicit C vtables, with C++ vtable
with its own compile time assertions and performance benefits.
It also makes use of `RefCountedPtr` wherever possible.
- We use C++ as an example to show how this API can be used while still
providing an idiomatic interface in the wrapped language of choice.
- No testing yet.
- Remove CredentialsFactory as it's unnecessary
- Effectively make Credentials a channel factory, allowing different credential types to create different channel types - this gives us a hook so that InsecureCredentials can at runtime instantiate a different kind of channel as required - giving us a way of generating an openssl free version of grpc++.
- Server credentials not touched yet, but they'll need to be updated.
- Changed the unsigned char * + size to NULL terminated strings which
makes sense for the PEM format. I may change TSI later (but the impact
will hopefully be much more limited).
- Added a way to pass multiple key/cert pairs to servers which is needed
when hosting more than one domain.
- Removed the C++ SSL credentials tests as we are going to have an
option to not specify the roots which will then be derived from the
environment (well-known platform dependent locations and/or
environment variable).
- Fixed the php build which is the only one added in the run_test.py.
This change will certainly break node, python and ruby.
