Truncate patch and tests

I'm attaching a patchset here. The first patch truncates non-block-aligned
headers. The second patch is a test which demonstrates that that's not
completely correct.

Swapping the header order seems to matter. The below is with no underruns.

Header 1: 1/4s - 1 byte
Header 2: 1/4s + 1 byte
The callback for Header 2 is never called, position is (1/2s - 1 byte), and
waveOutClose() gives STILLPLAYING.

But if you switch them around:
Header 1: 1/4s + 1 byte
Header 2: 1/4s - 1 byte
Both headers get callbacks, position is 1/2s, and waveOutClose() works
normally.

If you write either header alone, the callback occurs and waveOutClose()
operates normally.
