CAudioInput/Output: Apply VoIP latency in case of VoIP audio type

There was no implementation of setting specific latency value except default case.
An audio type can be set by audio_in[out]_set_sound_stream_info() and therefore
we can utilize the audio type to determine which latency type should be set.
If it is set, the audio core recoginizes it and set this stream with a specific
latency value.

VoIP type is one of the most common usecases for audio-io API. This case is
now added.

There are cases that focus or focus watch callback is used internally
for session backward compatibility. Because there has not been any mutex for
focus id, sometimes an unintended error happens accessed from another thread.
Now, a mutex for the focus id is added and operated to secure the critical section.

Fix exception handling of 'new' operator.

If it fails memory allocation by calling operator 'new', 'std:bad_alloc' exception will throw.
Therefore, never check null-pointer at next line. These situations cause potential leak also.
This patch uses exception handling of 'new' operator instead of checking null-pointer.
