Update to v080 release.

byuu says:

This release adds low-level emulation of the Hitachi HG51B169 DSP, which
was used in Mega Man X2 and Mega Man X3 as the Cx4 chip. It also fixes
a regression in both the sound core and cheat engine.

You will now need the HG51B169 data ROM to play MMX2/MMX3.

Once again, Cx4 LLE could not have been possible without the help of Dr.
Decapitator, Jonas Quinn, Overload and Segher. Be sure to thank them,
please!

Changelog:
* added Cx4 low-level emulation; removed Cx4 high-level emulation code
* fixed S-SMP synchronization to S-CPU on CPUIO writes
* controllers now have their own threads and classes
* serial controller is now emulated as an actual controller, rather than
  as a coprocessor
* added link coprocessor module for special chip research and homebrew
* fixed cheat codes that target mask ROM addresses [Cydrak]
* fixed compilation error with the latest GCC 4.6.0 beta releases
* added flexibility to XML memory mapping file format
* updated to mightymo's latest cheat pack (2011-06-20)
