Implement DetachedBuffer::Promote
1/ This enables a BufferHub-backed DetachedBuffer to be promoted into
the ProducerBuffer.
2/ Add DetachedBuffer::IsConnected in addition to
DetachedBuffer::IsValid.
3/ Cleaned up some using pdx:: namespace statements.

bufferhubd: Add DetachedBufferChannel
1/ Introduces four new BufferHub RPC operations.
2/ Implements the ProducerBufferDetach with test case.
3/ Also fixes a bug that Hangup signal wasn't propogated to the client
when bufferhubd closes a producer channel.

Remove legacy persistent BufferHub use case
This CL cleans up unused BufferHub code path. The motivation of doing
this is multifold:
1. Reduces future maintainace cost (e.g. when moving to libgui, there
will be less code to rename and re-style).
2. Removes unnecessary code complexity so that the code base is easier
and cleaner for future new reader to understand.
3. Prepares future work for supporting standalone GraphicBuffer in
BufferHub by avoid future logical and naming conflicts between
legacy PersistentBuffer/Detach/Attach and newly proposed detached
GraphicBuffer in BufferHub.

Add shared memory based buffer metadata
This CLs reduces BufferHub CPU consumption by adding asynchronous
state transition so that out-of-process VR composition can run on 2016
pixel devices smoothly. In addition, this CL addresses a couple corner
cases in the existing bufferhub logic, which fixes various blackscreen
issues.
1/ Tracks buffer transition states (gained, posted, acquired, released)
from the client side via atomic shared memory and adds
PostAsync/AcquireAsync/ReleaseAsync/GainAsync with metadata and
fence support.
2/ Adds dequeue order guarantee for buffers enqueued with
dvrWriteBufferQueuePostBuffer.
3/ Synchronous BuffeHub operations are still supported.
4/ Bump up the bufferhubd's soft limit of open file descriptor.
5/ Handle orphaned consumer in acquired state. This is a corner case
that consumer process goes aways (most likely due to a crash) leaving
buffer stuck in acquired state with inconsistent buffer state.
6/ Fixes a race condition for released buffer to be Gain'ed and
Acquire'd when a new consumer is created in released state.
7/ Improve silent consumer queue efficiency: Silent queues no longer
import buffers or receive signals about new buffers and they are
limited to only spawning other consumers and notifications about
producers hanging up.
8/ Modify PDX/UDS channel event signaling to work around epoll
behavior. PDX UDS uses a combination of an eventfd and an epoll set
to simulate the original PDX transport channel events. An odd
behavior discovered in the kernel implementation of epoll was found
that causes the epoll fd to "unsignal" itself whenever epoll_wait()
is called on it, regardless of whether it should still be
pending. This breaks the edge triggerd behavior in nested epoll sets
that channel events depend on. Since this is unlikely to ever be
fixed in the kernel we work around the behavior by using the epoll
set only as a logical OR of two eventfds and never calling
epoll_wait() on it. When polling is required we use regluar poll()
with the eventfds and data fd to avoid the bad behavior in
epoll_wait().
9/ Keep reading data after PDX hangup signal. UDS will signal hangup
when the other end of the socket closes. However, data could still be
in the kerenl buffer and should be consumed. Fix an issue where the
service misses an impulse sent right before the socket is closed.

Deprecate producer/consumer usage: Step 2
Clean up bufferhub_rpc, display_rpc and service side producer/consumer
usage reference.
Next (final) step is to remove all remaining client side reference to
producer/consumer usage and update dvr_xxx API.
This also fixes a minor typo in dvr_named_buffer-test

Update BufferHub service/client with support for gralloc1 usage.
- Add support for gralloc1 usage flags.
- Mimic how GraphicBuffer supports gralloc0 usage flags: (usage, usage).
- Move to using pdx::Status<T> since we're touching signatures everywhere.
