Update to v098r01 release.

byuu says:

Changelog:
- SFC: balanced profile removed
- SFC: performance profile removed
- SFC: code for handling non-threaded CPU, SMP, DSP, PPU removed
- SFC: Coprocessor, Controller (and expansion port) shared Thread code
  merged to SFC::Cothread
  - Cothread here just means "Thread with CPU affinity" (couldn't think
    of a better name, sorry)
- SFC: CPU now has vector<Thread*> coprocessors, peripherals;
  - this is the beginning of work to allow expansion port devices to be
    dynamically changed at run-time
- ruby: all audio drivers default to 48000hz instead of 22050hz now if
  no frequency is assigned
  - note: the WASAPI driver can default to whatever the native frequency
    is; doesn't have to be 48000hz
- tomoko: removed the ability to change the frequency from the UI (but
  it will display the frequency used)
- tomoko: removed the timing settings panel
  - the goal is to work toward smooth video via adaptive sync
  - the model is broken by not being in control of the audio frequency
    anyway
  - it's further broken by PAL running at 50hz and WSC running at 75hz
  - it was always broken anyway by SNES interlace timing varying from
    progressive timing
- higan: audio/ stub created (for now, it's just nall/dsp/ moved here
  and included as a header)
- higan: video/ stub created
- higan/GNUmakefile: now includes build rules for essential components
  (libco, emulator, audio, video)

The audio changes are in preparation to merge wareya's awesome WASAPI
work without the need for the nall/dsp resampler.
