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.

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.

112e9016c2 Some changes in bxhub and related code.
- Increase maximum number of Bochs client sessions to 6.
- Define bx_devmodel_c to 'void' for the bxhub case to simplify netmod code.
- Minor cleanups in bxhub and related vnet code.

0011092ddb Some work on the eth_vnet and bxhub code to reduce code duplication. Moved some
shared functions to netmod.cc and modified ARP, IPv4 and ICMP code.

027b3ffd41 Some work on the 'socket' networking module.
- bxhub.cc: Put all client data in a structure and added send_packet() function.
- bxhub.cc: Added SVN ID line.
- netmod.cc: Changed some DHCP messages to BX_DEBUG.
- eth_socket.cc: Minor cleanups.

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.

16e0130753 Switch back to the original 'vnet' ARP implementation.

fee79a2837 Removed the "slirp backend" networking module from the Bochs sources. It had
required an external binary and it couldn't be ported to Windows. Now the new
builtin and portable slirp support based on Qemu's implementation is almost
stable and all the 'vnet' DHCP and TFTP features have been ported to the new
slirp module.
TODO: rename all the "slirp_new" stuff to "slirp"

e62076e53d Somw work to make the new slirp module compile and work with MSVC
- added container_of() macro replacement
- fixed unresolved symbol in netmod.cc
- added MSVC-style structure packing pragmas
- check for the presence of min / max macros
- enabled slirp_new for MSVC in configure script
TODO list:
- check for more updates from Qemu
- fix lots of compiler warnings
- reduce code duplication with 'vnet' module (DHCP, TFTP, ARP)
- add separate config file for slirp to make it more flexible (using the
  'script' parameter)
- update MSVC workspace files
- add SMB support on Linux
- remove slirp backend module after next Bochs release

dfc71f8ae4 Applied patch for builtin "slirp" (user-mode networking) support. This version
is almost a port of the Qemu 1.1.2 implementation. It has been tested successfully
on Linux and Windows (MinGW/MSYS). The networking module is currently called
"slirp_new", since the "slirp" backend module still exists.

TODO list:
  - MSVC support (requires container_of() macro replacement)
  - apply fixes and improvements from recent Qemu releases
  - use our TFTP implementation to reduce code duplication
  - check if we can share ARP and DHCP support with "vnet"
  - add SMB support on Linux
  - finally remove the slirp backend module support

a5e5ac69b0 save the network configuration lines using the parameter tree
- fixed bochsrc line after a "raw byte" string parameter
- changed parameter name "macaddr" to "mac" (same as bochsrc option parameter)
- skip disabled parameters when building the bochsrc line
- added "multiline" switch to select the output format (one or multiple lines)
- renamed siminterface method and use it in the network devices code
