d51f6480a0 Some fixes for the "multiple NICs" support.
- Fixed ne2k parameter save function.
- For backward compatibility, card #0 defaults to PCI if the ne2k is assigned
  to at least one PCI slot.
- The "bootrom" parameter is only valid for the PCI card type.

835a745215 Added experimental "multiple NICs" support (currently NE2000 only). Unlike the
old SF patches this solution is compatible with the plugin architecture. The
ne2k plugin is loaded only once and a new ne2k_main_c object creates up to 4
ne2k device objects depending on the config. The new ne2k parameter "card"
specifies the zero-based card number to configure. If not given, the default
is card #0 for compatibility. The new ne2k parameter "type" specifies the bus
it is connected to ("isa" or "pci"). Card #0 defaults to PCI, the others to
ISA. In the PCI slot configuration the ne2k device can be used multiple times
if more than one card is configured.
Related changes:
- removed SMF stuff for ne2k
- always convert device prefix to uppercase (ne2k uses NE2K0 ... NE2K3)
- removed unused BXPN values
- TODO: add multiple NICs support for the E1000

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.

- 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.

18e138b0b4 Fixes and improvements for the network plugins changes in previous commit.
- In "non-plugin" mode loading and unloading network module is not necessary.
  Now enabled loading for the plugin mode only and removed unloading function
  for that case. The "pseudo plugin" entries of the dummy entry points are
  necessary to make sure the self-registering network driver objects are not
  optimized out.
- slirp / vnet: Since the plugin init function is not called in non-plugin
  mode, revert the instance count init change.
- Fixed a makefile dependecy.
- TODO: Implement self-registering objects in the sound driver code.

- 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.

d6166344eb Added ethernet module 'socket'. designed to connect two Bochs instances with
external program 'bxhub' (simulating a two port ethernet hub). It is based on
an old SF patch and it has been updated and extended:
- Windows support (tested with MinGW/MSYS and MSVC nmake).
- Command line arguments for 'bxhub' (base port number, MAC address, TFTP).
- Added support for DHCP, TFTP, ARP and ICMP echo (ping). It uses parts of the
  code for the 'vnet' module with some additions from the former "slirp backend".
- TODO: code cleanup to reduce duplication, rewrite of the networking plugins
  stuff similar to the work done with the sound drivers.

76a03aa1f0 Networking-related fixes
- bx_param_string_c method isempty() didn't work for raw byte strings. Now using
  it to check whether or not the current value matches the initial one. The
  parameter handling of the network adapters now use this method to check if
  the MAC address is already initialized to avoid incorrect BX_ERRORs.
- small documentation update
