Stewart Miles 568e66ff9e Modified submix buffer size accessors to use the pipe configuration. 
This change stores the period size (fraction of the pipe buffer size)
in the submix device's configuration which is then used to calculate
the input and output stream buffer size.

In addition, accessors for the input / output stream format have been
modified to use the pipe format in the device configuration rather than
returning hard coded values.

Default (and possibly architecture dependents) HAL modules go here. 


libhardware.so eventually should contain *just* the HAL hub
(hardware.c), everything in it should be rewritten as modules.

Modules are .so in /system/libs/hw/ and have a well defined naming
convention:

    /system/libs/hw/<*_HARDWARE_MODULE_ID>.<ro.product.board>.so
    /system/libs/hw/<*_HARDWARE_MODULE_ID>.<ro.board.platform>.so
    /system/libs/hw/<*_HARDWARE_MODULE_ID>.<ro.arch>.so
    /system/libs/hw/<*_HARDWARE_MODULE_ID>.default.so

They also have a well defined interface which lives in include/hardware/.

A module can have several variants: "default", "arch" and "board", and they're
loaded in the "board", "arch" and "default" order.
The source code for the "board" variant, usually lives under partners/...

The source code for "default" and "arch" would usually
live under hardware/modules/.
