Add support for property defining whether a DRC on the speaker path
 is enabled and will boost soft sounds.
Define new volume curves with more attenuations than existing ones
 to compensate for DRC-induced boost on sonification sounds to
 provide a more "linear" control to the user over the applied volume.

Bug 11600699

Change-Id: If23dd097a8b9b5ebb61e75dd8512ff75e63ba899

Do not allow offloading if one non offloadable effect is enabled. This prevents from
creating an offloaded track and tearing it down immediately after start when audioflinger
detects there is an active non offloadable effect.
Not doing so breaks gapless playback because AwesomePlayer will always be able to open
an offloaded track which will not be compatible with the previous PCM track and
Audiosink::open() will not recycle it.

commit a527ffd3 broke the selection of an available
direct output profile in getProfileForDirectOutput().
getProfileForDirectOutput() should check for direct output profiles
regardless of the flags provided to getOutput().

- Share existing offload output if compatible instead of
  creating a new one. Hardware has limited number of
  offload channels (possible only 1) so we must use as
  few as possible

- Changes to routing handling for offloaded outputs
