76b54ecb61 Renamed bx_pci_device_stub_c to bx_pci_device_c and derive it now from class
bx_devmodel_c. The early version of the combined vga / svga_cirrus code
required the now obsolete implementation. Some related cleanups in the
devices code.

d46a9b7205 Some work on the PCI devices code.
- Since the pci_read_handler() method is identical in most devices, move it
  to the base class to reduce code duplication. Only the 'pcidev' device has
  it's own implementation (NOTE: it is not maintained yet).
- Minor other fixes and cleanups in some PCI devices.

1df014a8ae Implemented unregister mechanism for runtime config handlers.
TODO: use it for removable devices with removable media (USB floppy / cdrom).

92f48fa92f Implemented MIDI output support for the ES1370 soundcard. Data written to the
UART data port is sent to file or device similar to the SB16.
Minor cleanups in the SB16 code.

a256414d32 Some work on the ES1370 emulation.
- Undocumented "legacy" register at offset 0x1b is used to probe for the ES1370
  interrupt by the Win9x driver. Using bit #0 to control the IRQ line fixes
  driver installation.
- Added more detailed BX_ERROR messages for the UART registers.
- Small code cleanup in the write handler.
- TODO: fix possible bluescreen in Win98 guest after wave playback.

7ce7c70f6d Adjust DAC output timer interval depending on real packet size (fixes output
with XP guest).

10d79f2e9a SB16: fixed output volume calculation.
ES1370: fixed and improved output volume calculation similar to SB16.
TODO: apply volume control to the FM output.

16d2957cd4 Rewrite of the ES1370 wave output code and related changes.
- Implemented wave output using the 'soundfile' driver including dual wave
  output in wavemode 3. Removed now obsolete output file handling and other
  cleanups. The wave input (recording) feature is not affected by the
  wavemode setting.
- Moved VOC file handling to the soundfile code.
- Updated iodev makefile dependencies.

b1e8a6369c Some work on the sound module handling and the SB16 midi file output.
- Added the capability to load up to 4 sound drivers and added methods to
  get pointers to the waveout, wavein and midiout services of a driver.
- Rewrite of the SB16 midi file output code. In midimode 2 and 3 the midiout
  service of the 'file' driver is used. Removed obsolete midi file handling.
- Re-implemented the closemidioutput() method to make runtime changes of the
  midi setup work with the new code.

f84439f8e8 Moved wave input support to a separate C++ class. The lowlevel sound module
creates the object and returns a pointer to it. TODO: Do the same with the
midiout feature.

0e73185efd Moved wave output support to a separate C++ class. The lowlevel sound module
creates the object and returns a pointer to it. TODO: The wavein and midiout
components should also move to separate classes. When finished, it should be
possible to configure the sound support more detailed (e.g. waveout with sdl,
midiout with alsa and the dummy driver for wavein). Creating a separate
module for the output to file(s) is also possible.

acd0fe11b5 Added volume control support per channel for stereo samples
TODO: do the same for mono samples (requires data doubling in emulation)

ea7997210d Some work on the wave volume control support
- ES1370: implemented CODEC registers (AK4531 mixer) and wave volume control
- Moved wave volume application code to new method pcm_apply_volume() and use
  it for both soundcards
- TODO: stereo support

3a22a7de61 Sound runtime options support completed
- SB16: log file name now also available as a runtime option
- SB16: changed order of the runtime options and minor other changes
- ES1370: changed the "wavemode" parameter type to bx_param_enum_c and set up
  more accurate dependencies (similar to SB16)
- ES1370: wave mode and file name now available as a runtime option

9a1d889359 ES1370: implemented wave output to file (raw and VOC format)
- added parameters 'wavemode' and 'wavefile' to the 'es1370' option
- ES1370: added new method sendwavepacket() (similar to SB16)
- moved VOC file methods from sb16.cc to soundmod.cc and added macros for them
- SB16: minor fixes

62a568c131 - changed license headers from LGPL to MIT for all devices / drivers that have
been ported from QEMU and originally have this license
- TODO: The QEMU people should verify the changes and tell us if something is
  missing. Bochs 2.6 will be released after everything has been confirmed to
  be okay.

c6bd3fb60c - moved the sound stuff to the new subdirectory iodev/sound
- TODO #1: update MSVC workspace files
- TODO #2: these 'device classes' could be moved to subdirectories, too:
  - pci (when we have more than one chipset)
  - display (when we have one more device and vga / cirrus cleaned up)
