614ecd7455 Some fixes for the vnet module found with TCP / FTP testing code.
Fixed maximum size of an ethernet packet (1460 bytes TCP user data + headers).
Don't activate timer for a new packet if another is still pending.

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.

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.

a8f1834c38 slirp / vnet TFTP support:
Detect and reply all supported TFTP extension options for both read and write
operations. Use 'blksize' value if smaller than buffer size.
TODO: increase buffer size, implement timeout mechanism
