4dd5816108 Some changes in the Bochs plugins code.
- Changed variable type of the plugin_t "type" member from enum to Bit16u.
- Added support for returning device flags with the new mode PLUGIN_FLAGS in
  the plugin entry functions. It is currently only used for devices that can
  be connected to a PCI slot.
- Code cleanup in core device plugins: checking type no longer necessary.
- The "non-plugin" mode now also uses the "loadtype" member of plugin_t.

TODO: Change PCI slot options to bx_param_enum_c and build the choices list
using the new capabilities of the plugin API.

0d425037df Improved plugin type detection at Bochs startup.
- Added special mode to all plugin entry functions that returns the plugin type.
- The plugins search function now temporarily loads all available plugins and
  reads the plugin type using the new mode PLUGIN_PROBE.
- Added "loadtype" to the plugin structure to store the type used for plugin
  loading (currently only the voodoo plugin provides two types).

74deb16b44 Since externally developed optional device plugins (AKA "user plugins") can be
loaded in bochsrc with "plugin_ctrl" or with their own name, the user plugin
option and the special cases for PLUGTYPE_USER are no longer needed. Updated
example patch to make it work with the latest SVN code.

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).

e5c68dd4ac Rewrite of the optional plugin control feature.
- Now that we know about all available plugins at startup, the bx_list_c object
  "plugin_ctrl" contains a fixed number of bx_param_bool_c objects representing
  the requested status (1 = load). It is verified at simulation startup.
- The config interface creates two text lists (textconfig) or list boxes (win32,
  wx) from it to show the remaining available and the loaded plugins. Loading
  and unloading is performed immediately and plugins may install / uninstall
  options in other menus / dialogs.
- Modified the "non-plugin" code to make the optional plugin control work very
  similar in this mode.

4f311f0618 Some work on the Bochs plugins support.
- Added suffix "_gui" to the base name of display library plugins.
- Added new function plugins_search() that browses the plugin folder(s) and
  detects the type from the library name. Plugins with no prefix or suffix are
  treated as i/o device plugins. The plugin_load() function uses this database.
- Some related fixes and cleanups.

b880fb2975 Rewrite of the hdimage plugin code.
- Common hdimage code, lowlevel cdrom code and the classes for the Bochs "own"
  image modes (e.g. flat, sparse, growing") are now a part of the Bochs core.
- All classes for image modes present in separate files are now built as
  plugins with the same self register mechanism as network, sound and usb
  modules. Defined new plugin type PLUGTYPE_HDIMAGE.
- Temporarily disabled the base image format detection of the undoable/volatile
  modes for the "external" modes in the plugins case.
- TODO: Bochs should know about all of the available plugins and their
  capabilities right after startup, but before the configuration stage.

d25e85c21a Preparing improved VGA extension support and some VGA / Cirrus cleanups.
- Treat VGA extension name other than "none", "vbe" or "cirrus" as a VGA
  compatible device plugin and try to load it.
- Added new plugin type PLUGTYPE_VGA for such a plugins (interally handled like
  a core plugin).
- Added panic in devices init for the case no VGA compatible plugin is present.
- Added new method vga_redraw_area() that handles the non-VGA and null size
  case. The specific method redraw_area() is called otherwise.
- Moved init_systemtimer() call from extension code to init_standard_vga().
- TODO: Implement VGA subsystem in the Voodoo code to test the new feature.
  Voodoo Banshee 2D accelerator code needs to be written to make this really
  useful.

bd1eb0f862 Rewrite of the USB devices plugin code similar to the network driver code.
- Removed "pseudo device plugin" containing common code and all connectable
  USB devices.
- Moved USB device base class and module handling to the Bochs core.
  Now loading USB device plugins in usb_common.cc.
- Created separate plugins for each USB device implementation.
- Modified Bochs plugin system to support new plugin type PLUGTYPE_USBDEV.
- Added entries for the non-plugin case similar to the network and sound stuff.

758f4de4d4 Rewrite of the network driver plugin code.
- Removed "pseudo device plugin" containing common code and specific drivers.
- Moved network module base classes and module handling to the Bochs core.
  Now loading network driver plugins in netmod.cc.
- Moved shared networking code used by the 'vnet' driver and 'bxhub' from
  netmod.cc/.h to new files netutil.cc/.h.
- Created separate plugins for each network driver implementation.
- Modified Bochs plugin system to support new plugin type PLUGTYPE_NETWORK.

60d24943c6 Rewrite of the sound driver plugin code.
- Renamed OSS sound driver files from soundlnx.cc/.h to soundoss.cc/.h.
- Removed "pseudo device plugin" containing common code and specific drivers.
- Moved common sound code, base classes of sound drivers and the dummy driver
  to the Bochs core. Now loading sound driver plugins in soundmod.cc.
- Created separate plugins for the platform/library specific drivers and the
  "file" driver.
- Modified Bochs plugin system to support now plugin type PLUGTYPE_SOUND.

f33093549b Modified plugin system to support the new PLUGTYPE_GUI.
- Changed the name of the entry point of the gui plugin code to
  lib{gui_name}_gui_plugin_init(). It is used when loading plugin with the new
  type. Added gui init code for the non-plugin version in plugin.cc.
- Some related changes for the "wx" case.
- The function load_and_init_display_lib() now only returns 1 on success.
- Minor other changes.

a767ec0b1b The plugin version now uses the native DLL handling code for all Windows ports.
Skip configure checks for libtool / ltdl and no longer link with mingwex.

58019a1649 Renamed "ltdl.h" to "ltdl-bochs.h" to avoid conflicts with the include file
that is a part of the libtool package. Updated Makefile dependencies.
TODO: check if we can get rid of the ltdl*.* files (this would be possible if
the ltdl library is always available if libtool is present).

5c49e2458f - added new plugin type PLUGTYPE_STANDARD for optional plugins which are used in
nearly all cases and plugins that depend on others. These plugins cannot be
  managed with 'plugin_ctrl' (e.g. keyboard, harddrv, pci_ide). Store the plugin
  type in the divice structure for compatiblity with the "no-plugin" compilation.
  Call the device methods init(), reset() and after_restore_state() for each type
  separately in the order: stanard, optional, user. This also affects the status
  bar LED feature: now the keyboard and harddrv LEDs are always visible, but
  those of optional plugins may be invisible if there is no space left.
- TODO #1: add the devices 'ne2k' and 'sb16' to 'plugin_ctrl'
- TODO #2: manage core plugins with the device plugin system

38a797f502 - added function for loading optional plugins in case the plugin support is
turned off. Removed workaround code from devices.cc.
- removed 'pci_ide' plugin from the optional plugin control, since it depends
  on the presence of 'pci' and 'harddrv'.
- define types for plugin init/fini functions

6a42228075 - first step for DLL plugin support with MSVC. Now the BOCHS.EXE with plugin
support compiles and links fine and the main object files for the plugin DLLs
  are created. Since the gui and iodev makefiles are not ready yet, the link
  stage must be done manually. Support for the search path defined in
  LTDL_LIBRARY_PATH should be added when the DLL plugins compile and work.

5744c1cb90 - include "ltdl.h" with quotes, instead of <ltdl.h> with <>'s. It's
supposed to be a local header file, not a system header file.
