e34d017f60 Some fixes for compiling for WIN64 with MSVC.
- Added check in config.h whether or not Bochs is configured and compiled for
  the same target platform (WIN32 / WIN64).
- Fixed some warnings that occur in the MSVC WIN64 case.

96193ed79c Finished bx_bool to bool type changes.
- Changes in the USB host controller code.
- Finally removed bx_bool type definition.
- NOTE: The Bochs BIOS still has it's own bx_bool definition.

aaf8c9d4e4 Removed "svga" display library designed for the obsolete Linux SVGALib.
The latest release is from 2001 and it will not work on modern Linux systems.
Parts of the SVGALib code have been moved to the Linux kernel and the X11 and
SDL libraries are using it as a video driver.

c05cb5e1d7 Removed legacy "load32bitOShack" feature. In the early days of Bochs some hacks
were required to load a 32 bit OS. In the meantime Bochs has been made capable
of loading 32 and 64 bit OS's without hacking.

762d2a35af Some work on the "multiple NICs" support.
- Added support for the E1000 network card similar to ne2k implementation.
- Define BX_NE2K_MAX_DEVS to make the maximum number of devices variable.

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

  - Supervisor Shadow Stack EPT Control is not implemented yet
  - SMM placing for SSP
Currently have to be added manually to some CPUID model, for example to ICL-U

9a27303afa Some work for GTK version 3 compatiblity
- if wxGTK uses GTK 3.x, also use it for the gui debugger to avoid trouble
- the name of the include file for GDK keysyms now depends on GDK version, so
  the temporary translation table can be removed
- small fix to compile the gui debugger with GTK 3.x (warnings still exist)

e1d8bedbb5 Added symbol BX_LOAD32BITOSHACK to disable this legacy feature. With the
latest BIOS images 32-bit and even 64-bit guest OS's are known to boot inside
of Bochs without hacking. This legacy hack could be removed after next release
if nobody complains.

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.

f844e846b7 Added PCM output data resampling in a separate thread. The resampler requires
either libsamplerate or the SoX resampler library installed. If not installed,
the data is only copied to the output buffer and sample rate of the output
driver is changed similar to legacy code. Related changes:
- Added check for libsamplerate or SoX resampler header files in configure
  script.
- Added functions for converting source format to float (requied by resampler)
  and float to output format.
- Added support for float type data in the audio buffer code. Buffer chain #0
  receives float data from sendwavepacket() and buffer #1 receives data for
  mixing and output in format "16-bit signed little endian stereo".
- ALSA: Disable builtin resampling feature if resampler is present to avoid
  doing it twice.

0ba744b9fe Started implementing USB EHCI support. The PCI and MMIO register behaviour is
almost implemented, the port owner handling and the UHCI companion controllers
are present. High speed devices are not yet supported, since the EHCI scheduler
code has not been written yet (e.g. porting from Qemu). Low and full speed
devices should be detected correctly and work after port ownership change to
UHCI. 6 ports are available and the bochsrc syntax is similar to other HCs.

696c1a6e55 Some Bochs features are still called "experimental". The bus mouse, USB OHCI,
USB UHCI and the E1000 NIC are known to work fine on some guest systems, so
it's safe to remove this attribute.
TODO: Some other Bochs features need to be reviewed for this.

8d1e3b2ac1 Added statistics collection infrastructure in Bochs and
implemented important CPU statistics which were used for Bochs CPU model performance analysis.
old statistics code from paging.cc and cpu.cc is replaced with new infrastructure.

In order to enale statitics collection in Bochs CPU:

- Enable statistics @ compilation time in cpu/cpustats.h
- Dump statistics periodically by adding -dumpstats N into Bochs command line

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.

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
