From: Archie Pusaka <apusaka@chromium.org>

The valid range of volume is 0 - 127, yet it is stored in 16bit
data type. This patch modifies it so we use 8bit data type to
store volume instead. Furthermore we also use signed type, so
negative values can be used to indicate invalid volume.

Changes in v4:
-Use int8_t instead of uint8_t

Changes in v3: None

From: Archie Pusaka <apusaka@chromium.org>

Sometimes the response of RegisterNotification for volume change
event came before we create the transport for the corresponding
device. If that happens, the volume will be stuck to an
uninitialized invalid value. The property Volume of
MediaTransport1 will also be left unaccessible.

This patch supplies the initial volume when creating a new
transport. The value is obtained from the media_player object.
However, since the avrcp session might not be created by the time
the transport is created, we also try to initialize the volume
when creating avrcp session.

Reviewed-by: Yu Liu <yudiliu@google.com>

Changes in v4: None
Changes in v3:
-Add missing library

Changes in v2:
-Get the volume from media_player instead of from separate list
