include: Add function declarations for CoAllowSetForegroundWindow and CoRegisterChannelHook to objbase.h.

wined3d: Cleanup & merge pshader_get_input_register_swizzle() and vshader_program_add_input_param_swizzle().

As spotted by Christoph Bumiller, these branches are now never
reached. Also, at least in the case of WINED3DSIO_TEXM3x3SPEC and
WINED3DSIO_TEXM3x3VSPEC the old code was not quite correct, since we
can lookup rather than guess the texture type these days.

When querying a listview subitem for the user param, the main item's
user param is returned. Also, when a subitem is custom-drawn, the main
item's user param is passed along.

With help from Ken Thomases.

make_makefiles: In .gitignore, explicitly list files that we know are generated instead of using wildcards.

Also, added some output formats that Core Audio ought to be able to handle.

wodSendNotifyInputCompletionsMessage sends the kWaveInNotifyCompletionsMessage
to the message thread, which calls widHelper_NotifyCompletions.

It scans for completed input wavehdrs, removes them from the queue,
and notifies the application that they're done.

It now returns in an output parameter the frame count that the AU will use.
Also, initialize the Audio Unit.
