fb265dc532 Ported OPL3 emulation from DOSBox.
The code currently only works with the SDL sound output module and at 44100 Hz,
with 16 bit stereo signed little endian format. FM volume control and
save/restore support are not implemented yet. The legacy code for generating
MIDI notes still works and will be removed when mixing support is implemented
in all sound modules.

f9ff6ece2d Applied some parts of the floppy patch by Ben Lunt.
- The "Read ID" command must return an error when reading with non-existant head.
- Some BX_DEBUG improvements and minor other changes.

fe49c73a6b Some work on the lowlevel sound support.
- Define new structure bx_pcm_param_t and use it as a parameter for the method
  sendwavepacket(). The method startwavepacket() is now called from
  sendwavepacket() in case of a parameter change (temporary solution).
- soundsdl: Replaced waveready() call by some more accurate code for buffer
            space check in sendwavepacket().
- soundsdl: Moved code for reading from audio buffer to a new function.
- soundsdl: Temporarily increase the audio buffer size.
- Preparing the SB16 code for the OPL emulation port from DOSBox.

7bd5eeaa87 Mix the wave input using SDL_MixAudio() (addition and clipping).
NOTE: This function is not correct in case of more than 2 active sources.

fe953485b1 Some more work in the lowlevel sound code.
- Reworked wave callback code to support 2 input sources (no mixing yet).
- Fixed SDL sound output.
- Beep generator fixes.
- Prepared the SB16 code for FM OPL output support (to be ported from DOSBox).

2ca192eef7 Some more work in the lowlevel sound code.
- Renamed wavedata callback type.
- Handle sample rate in the beep generator (TODO: handle data format).
- Don't call waveready() in the SB16 code.
- Attempt to fix SDL2 wave output using SDL_LockAudio() / SDL_UnlockAudio().
- SDL specific code in the beep thread no longer needed.

0c205fce26 Some work in the lowlevel sound code.
- Added framework for polling wave data and use it for beep output in sdl.
- Some work in the beep thread code (to be continued).
- Moved macros required for multithreading to bochs.h.

c7c92bb62b Fixed OPL chip detection.
- Increment timer counter before checking for overflow.
- Implemented ISA bus delay in the pc_system code and use it for the SB16.
  This makes OPL chip detection work at ips values > 4 Mips.
TODO: OPL chip should use wave output instead of MIDI (maybe port from DOSBox).
TODO: Use isa_bus_delay() for other legacy devices if required.

65d2bb11eb Release all pressed keys when the Bochs window gets back the keyboard focus.
- feature implemented in the wxWidgets gui
- feature not required for legacy SDL (releases keys on focus change)
- removed duplicate code in keyboard.cc

59f5a03af6 Rewrite of the virtual timer code to support both modes at the same timer.
The timers now have a new member 'realtime' and they are driven by the
selected engine. The VGA update timer and the status LED timer now always use
the realtime mode, but the PIT and CMOS RTC depend on the clock options.

d012670927 Applied the usb_xhci part of the USB patch by Ben Lunt.
Notes by Ben:
This emulates a NEC/Renesas uPD720202 2-port (2 socket, 4-port register sets)
Root Hub xHCI Host Controller.
Many, many thanks to Renesas for their work and effort in helping my research.

I have tested in with my own tests and WinXP Home Edition SP3.

Use port1 and port2 to emulate a Super-speed device, and use port3 and port4
to emulate Low-, Full-, or High-speed devices.

NOTE: The Windows driver for this device uses a proprietary detection
mechanism and we don't have the permission to implement it. That's why it only
works fine with non-Windows guests.
