Removed non existing header file from libspeex Visual Studio 2012 project. This makes Visual Studio understand that the lib is built correctly.

regression from 8f82979d using wrong values to calculate buffer size

This amends commit b9a85831.

The rebuild is needed for commit d3b9aaba.

If this is set to true (default false) we assume the storage-dir is
shared, organized by realm/domain, with uses other than voicemail, so
we adopt a directory structure of:

  <storage_dir>/<realm>/voicemail/<id>

This replaces the semantics of the storage-dir parameter without the
deprecation notice.  The behavior of storage-dir never should have
been deprecated, though it was probably correct to deprecate the name
itself.

Rather than having both vm-storage-dir and vm-domain-storage-dir it
might be nice if the config system could just notice at what level it
was defined and do the right thing.  Indeed, this is why I'd left
things as-is for so long.

But as Master Foo famously said, "which one will reach the other side
of the river: the one who dreams of a raft, or the one that hitchhikes
to the next bridge?"

Some OSes like linux provide a mechanism for sending TCP keepalive
pings.  Sofia provides its own mechanism for doing this in userspace.
We shouldn't conflate these two mechanisms.
