Speex patch using speex_lib_get_mode()

Using speex rc1 compiled with GCC against GStreamer compiled with MSVC results
in fatal crashes using a simple pipeline such as:

audiotestsrc ! speexenc ! speexdec ! fakesink

The attached patch resolves the problem by accessing speex modes through
speex_lib_get_mode() instead of directly through speex_nb_mode, speex_wb_mode,
and friends.

Speex had to be compiled with --disable-sse presumably because of stack
alignment issues between GCC and MSVC (but that's an issue for the speex folks
to resolve).

I do not know if it works with a statically linked libspeex. Works fine with a
shared library.
