Summary: audioop - alaw encoding/decoding added, code updated

Initial Comment:
This patch adds a-LAW encoding to audioop and replaces[1] the old 
u-LAW encoding/decoding code with the current code from sox.

If audioop has an ulaw codec, it should also have an alaw codec. 
Besides, shtoom wants/needs it.

Tests and documentation are updated with this patch too.

The patch is a unified diff against CVS that can be applied in one 
piece frrom the root of the python tree.

Beyond the cursory tests in the unittests, I have done 
successful tests with real-life data.

Possible issues: the code from sox uses int16_t.

[1] Rationale for the replacement of existing code: the alaw code 
would have been different in style from the ulaw code and attribution 
of the code would have been less clear.
