529dddda53 audio: Bug fix: Fill empty data even when audio is suspended 
When writing is stopped on Oto's players, unexpected delaying
happens.

The ideal solution is to have APIs to suspend and resume Oto's
player, but this is not easy. For a temporary solution, write
zero values on the players when audio is suspended.

124389561c audio: Bug fix: The dummy player should have long enough buffer 
In the current implementation, the audio context will be ready
when a player's Write is finished. If the buffer is too short,
Write finishes immediately without accessing the low audio layer
and the audio context would be ready without playing anything.

This change changes the dummy buffer to have a long enough buffer
so that Write will be wait for acutual audio playing.

Fixes #970

b78f678700 audio: Bug fix: (*Context).IsReady never returned true unless there is a player 
The audio context is never ready unless there is a player. This is
problematic when a user tries to play audio after the context is
ready. Play a dummy player to avoid the blocking.

e4f0a0aa04 audio: Bug fix: Remove depenency on finalizer 
This change fixes playerImpl leak by removing dependency on
finalizer usages. Now readLoop can (or should) be called multiple
times even after closing. Only when (*Player).Close is called
explicitly, the read loop cannot be started again.

273093b237 audio: Skip the player in the state of starting, seeking or EOF 
This is basically reland of
2fee7a6fe5.

Before this change, if a player's buffer was not enough for
reading, 0 value were used and this caused noises. The reading
size should be aligned with all the players.

However, there are some cases that the player should be skippped.
For example, just after a player just starts playing or seeking,
the buffer is empty. In this case, other players should not wait
for the player since decoding might take some time. Another case
is that the player reached EOF.

This change aligns the read buffer sizes but use zero values only
when the player just starts or seeks, or reaches EOF.
