am 83410a85: Avoid prematurely terminating parsing when some track only has a single access unit

             * 1. "M4WAR_NO_MORE_AU == err" indicates that there is no more

             * access unit from the current track. In other words, there

             * is only a single access unit from the current track, and

             * the parsing of this track has reached EOS. The reason why

             * the first access unit needs to be parsed here is because for

             * some audio codec (like AAC), the very first access unit

             * must be decoded before its configuration/encoding parameters

             * (such as # of channels and sample rate) can be correctly

             * determined.

             *

             * 2. "trackCount > pC->mCurrTrack" indicates that there are other

             * tracks to be parsed, in addition to the current track.

             *

             * When both conditions 1 & 2 hold, other tracks should be

             * parsed. Thus, we should not bail out.
