Change the CCHelper class to be an instanced instead of a static
pattern. The CCHelper instances all share an interface to the common
clock service and register/unregister a callback handler in response
to there being CCHelper instance in the system or not. This brings
usage of the CCHelper into like with the new auto-disable
functionality of the common time service. For any given process,
whenever there are CCHelper instances active, the process will
maintain a callback target to the common clock service and will be
considered to be an active client.
Also change all of the users of the CCHelper interface to manage the
lifecycle of their new CCHelper instances.

Bulk name change to remove references to Android@Home from the common time
service in preparation for cleanup and up-integration into the master
branch. Basically, aah_timesrv is now common_time.

* Added a MediaPlayer.setMediaPlayerType API that be called to specify the
desired media player implementation before calling setDataSource
* Implemented setDataSource(fd) in the AAH_TxPlayer

Introduce a heartbeat timeout for TX senders. If none of the TX
sender's clients send any packets for this timeout period (10 minutes
right now), then the sender will stop sending keep-alive heartbeats.
This should cause RX clients to release any held media resources,
including any timed audio track. Releasing timeed audio tracks allows
the audio system to go into its idle state, which allows the power amp
in Tungsten to power all of the way down, saving both heat and power.

First, clear an issue which was causing an assert to fire. Basically,
once a decoder pump had entered the error state and was shutdown, it
was not clearing its status, and when a substream attempt to recycle
the pump, startup was failing an assert (no thread had been created,
meaning that the system was not initialized, yet status indicated an
error). This was a small one-liner in aah_decoder_pump.cpp.
Second, try to become a little nuanced about how we handle errors in
the decoder pump. A comment in the code pretty much says it all, but
the summary is that we don't want to completely abort playback because
a single chunk of ES failed to decode, but if nothing is decoding and
we are making no progress at all, we probably need to put the
MediaPlayer instance into the fatal Error state and signal the app
level so that further action can be taken (automatic recovery attempts
followed by bug reports and signalling the user if those fail).
This is to address the fallout of http://b/issue?id=5498460, where
something at the OMX decoder level becomes unhappy about not being
able to obtain an output buffer which eventually unwinds to this
assert which results in a dead mediaserver. After this change, the
mediaserver will no longer crash, and may even recover (depending on
whether or not the OMX unhappiness is transient or not), but the
primary issue (unhappy OMX) is probably still around. It is quite
difficult to reproduce, I will probably need to open a different bug
to track that issue.

Music2 would prefer a configuration interface that takes a single
blob of data passed in from the RPC client and then passes it
opaquely to the media player. This eliminates the need for Music2
to rev their application if we add more configuration options to
the TX player.

Previously, sequence numbers for audio packets were assigned by the
TX player before packets were queued to the sender. This caused a
race between assignment of sequence numbers on audio packets and
sequence numbers on heartbeat packets. A heartbeat could get queued
and added to the retry buffer before an audio packet with an earlier
sequence number got queued.
This CL centralizes packet sequence number assignment and insertion
into the retry buffer inside AAH_TXSender::doSendPacket_l. It also
makes explicit what operations can be done on a TRTPPacket before
and after packing.
