This allows to clean the doc directory from the parent project dir.
The command:
make -C doc clean

does not work as long as the paths specified in doc/Makefile are relative
to the parent dir.

Also it is consitent with "testclean" and "distclean" targets.

With these commands it is possible to add HTML and non-HTML snippets,
which will be useful for the "See Also" manual chapters.

Fix a few warnings generated when creating the manuals.

Our current doc generation toolchain does not allow to reference external
documents.

Fixes out of array accesses

Every call to CoInitialize should have a matching CoUnititalize.

Based on patch by Don Moir <donmoir@comcast.net>.

Handling DirectShow events prevents infinite loops when there is an error in
the graph, such as a device being disconnected. This makes it possible for
dshow to return an error to the caller and run the cleanup code.

It adds unnecessary complication for insignificant usability improvement.
The user really should know if they'll need resampling compensation before
opening the context.

Note that only the documentation has changed. The current functionality will
still work until the next major bump.

This prevents a null pointer dereference

Refactor calculating the max payload size, to avoid hardcoding the
