8db0a2b001 Replaced the plugin init / fini functions with one single function called
plugin_entry(). The additional boolean argument "init" is used to select the
requested action. The entry points still have unique names for compatibility
with the "non-plugin" compilation. Added macros for setting up these names
(e.g. PLUGIN_ENTRY_FOR_MODULE for device plugins).

0c24af112d Fixed two issues found with valgrind: Since runtime parameters are revoved by
the destructor, the main parameters must be removed after deleting device object.

8952c144bd Some work on the i440BX chipset and related changes.
- Fixed PCI BAR initialization (now using memset()).
  - Fixed reset failure (set all PAM memory types to ROM).
  - Added stub for the AGP aperture (register BAR #0, handle APSIZE and read
    GART entry in read/write handlers).
  - Added some more PCI register defaults and write masks.
  - Fixed a warning in the ES1370 code.
  - Voodoo Banshee: set up PCI subsystem ID depending on bus and model.

87145baf61 Rewrite of the PCI base address (BAR) handling to reduce code duplication.
- Added new structure bx_pci_bar_t that contains all parameters related to the
  PCI BARs (type, size, address and r/w handlers).
- Added new methods init_bar_io() and init_bar_mem() to set up the new structure
  in the pci device init code.
- Added new method pci_write_handler_common() to handle writes to the normal
  BARs and the ROM BAR. Writes to other registers are forwarded to the device
  specific PCI write handlers. Removed BAR and ROM BAR handling from the
  specific code.
- Added new method pci_bar_change_notify() to execute specific code after BAR
  update (vga, ne2k).
- Moved normal BAR handling to method after_restore_pci_state().
- Store pointer to PCI device name in bx_pci_device_c and use it for i/o setup.

c897ffa619 Cleanups in the Bochs system timer 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.

  "file" driver.
- Modified Bochs plugin system to support now plugin type PLUGTYPE_SOUND.

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.

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.

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.

29d40bf9fe Added an optional device-specific Bit8u parameter to the timer structure.
A device can set it with setTimerParam() and read it in the timer handled using
triggeredTimerParam(). Simplified some timer handler by using these methods.

ae659d14fd Changed initial value of the parameter "enabled" to 1 for network, sound and
usb device plugins. Loading the plugin means that the user wants to enable it.
Disabling the device on the command line and in the config interface is still
possible.

dd794d6d44 Some more work on the 'sound' bochsrc option
- added 'wavein' parameter to specify the wave input device if necessary
 - if 'wavein' is not set, Bochs uses the 'waveout' value for input, too
 - SB16: the 'wave' parameter is now only used to specify the filename (mode 2 or 3)
