Grpclite fallout (#235)

* First stab at a stream-based Channel implementation

* tests; basic parsing

* server rig and logging

* starting to get server talking

* basic unary server handling

* flush buffers; correctly track frame count when writing

* working end-to-end unary?

* change header to 8 bytes; lots of evil; explore TFMs

* move things around; use buffer doubling

* yak

* getting ducks in a row

* duplex... works!?

* gates and connection factories (incomplete)

* closer on rework

* so I wrote a memory manager... it seemed like a good idea at the time

* it compiles!

* Building for all TFMs again

* debug serialize

* things aren't listening

* all tests passing

* memory cleanup

* multi-segment buffer

* push model; basic tests working again

* cleanup; check which thread is doing what

* cleanup

* fixings

* unification of stream handlers

* async executor... probably works?

* move all the things to get the memory moving in the right direction

* reader-loop on connection (pull rather than push)

* test server/rig

* get rig almost working

* encouraging numbers; twice the throughput for hello-world examples

* - fix broken rig (cancellation not being applied; client-trailers not being sent for client-streaming/duplex)
- add markdown output

* show results with/without output merge (dup key)

* make output easier to understand:

* fix glitches with buffers that cross boundaries

* Add TCP support

* nit namespaces

* TLS named-pipe test; tidy up enum prefixes

* implement out-of-band cancellation

* tidy up stream termination make the frame-write-flags be not part of the frame itself

* fix pipe reader; failed to implement pipe server on Kestrel

* fix pool buffering
