b=1033140 make speex_resampler declarations consistent with OUTSIDE_SPEEX implementation r=padenot Instead of defining OUTSIDE_SPEEX and RANDOM_PREFIX everywhere speex_resampler.h is included, it is easier to patch the header. Symbol names in gkmedias symbols.def are updated now that RANDOM_PREFIX is taking effect, and unused symbols are no longer exported.
