When "speex/speex_resampler.h" was included, another exported header (in
dist/include) would find the speex/speex_resampler.h in dist/include before
dist/system_wrappers. Visibility of undefined symbols depended on the order
of includes.
This patch changes includes to <speex/speex_resampler.h> so that
WRAP_SYSTEM_INCLUDES works as expected but removes the wrapper when not using
GKMEDIAS_SHARED_LIBRARY.

Also change WebAudioUtils from a class to a namespace, so that constant
variables can be defined inline with internal linkage.
static class variables cannot be defined inline because this violates the one
definition rule, even though some compilers may not notice.

The difference from Blink here is that Blink plays silence for if element
channel counts are > 32, but here more channels are down-mixed. Media stream
channel counts are also fixed to 2 in Blink, but that restriction is not
applied here.
Leaving the "inline" const static/class member initialization of
MaxChannelCount left missing symbols with gcc 4.7.3.
