762d2a35af Some work on the "multiple NICs" support. 
- Added support for the E1000 network card similar to ne2k implementation.

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.

Volker Ruppert
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

c4d0001229 Apply SF [patch:#549] Fix snapshot param overflowing 32-bit integers 
This patch fixed an integer overflow issue when restoring a snapshot whose parameters that are larger than ULONG_MAX.
We run into this issue when restoring a Windows snapshot whose pc_system.ticksTotal exceeds ULONG_MAX, which caused the subsequent confusion in bx_virt_timer_c::timer_handler which relies on pc_system.ticksTotal to function correctly.
