Capture configuration was using cached_output_hardware_config
instead of cached_input_hardware_config.
Also enable mono capture by rejecting first attempt to open
an input stream in mono with -EINVAL error: AudioFlinger will reopen in
stereo and do the channel conversion.

If an event packet is read containing an unknown sensor handle,
don't pass it on to Sensor Services. Drop it on the floor instead
as it's causing Sensor Services to crash.
Moved read of queue size in sensors_poll_context_t::poll() to post
queue mutex grab for safety.

When channel conversion is enabled and the pipe is opened with less channels
(e.g 1) than the output stream's channels (e.g 2) the input stream's buffer
size was calculated incorrectly which resulted in the input stream buffer size
being larger than the output stream buffer size in terms of time. This
changes the pipe size to take into the account maximum frame size so the
output stream buffer size will be greater or equal to the input stream buffer
size.
In addition, if the pipe is created when the input stream is opened and the
output stream is opened at a different sample rate (e.g input = 8KHz,
output = 48Khz) the pipe will incorrectly rate limit writes to the pipe
resulting in gaps of silence in the data read from the pipe by the input
stream.

As described in If592270a17e08c5852b00b730bb9c5166c746ad2 the audio mixer
doesn't work correctly when sending data to an output device that supports
a sample rate that is more than 2x different to the source data rate.
This modifies the remote submix module to resample data from the pipe
when it's read from the input stream.

The AudioFlinger service currently will only open stereo streams from
mono AudioTracks since all mixing is performed in stereo and then sent
to the HAL stream. In order to allow a process to record a mono stream
from the submix HAL, this change implements channel conversion in
the submix HAL so that it's possible to open the output stream in stereo
and the input stream in mono.

Since it's possible to open an output stream on the submix HAL before the input
stream is open, writes to the output stream that fill the shared pipe result in
indefinitely blocking the thread writing to the stream. This change modifies
the behavior of writes to a submix output stream such that if a write would
result in blocking the thread and an input isn't open, the pipe is flushed
of the appropriate amount of data such that the write will not block.

This change is primarily being made as a short term solution to allow an input
audio stream received over the network to be fed into an audio input stream (e.g
the MIC stream) when a physical audio input device isn't present.
This makes both the input and output streams owners of the pipe so that
creation order no longer matters. In addition, it works around a memory leak
caused by applications that never close input streams.

This modifies the submix module to allow the internal buffer to be any NBAIO
format. This is useful when sending audio of arbitrary formats between
processes. AudioFlinger continues to enforce format restrictions as specified
by the device specific audio_policy.conf so the submix streams will have the
same restrictions as before.

This change stores the period size (fraction of the pipe buffer size)
in the submix device's configuration which is then used to calculate
the input and output stream buffer size.
In addition, accessors for the input / output stream format have been
modified to use the pipe format in the device configuration rather than
returning hard coded values.

This change cleans up casting from contained to container structures.
Such that if..
struct child {
struct parent;
int child_data;
};
is changed to...
struct child {
int child_data;
struct parent;
};
functions that cast from "parent" to "child" will continue to function
correctly.

It also adds checks and warnings if bad sensor HALs provide
garbage sensor handles in their sensor events.
Tested by making sure pedometer and tilt still work.
