add HDD support + fixes

Patch-Author: Andrew Warkentin <andreww591!gmail>
Patch-Message-ID: <50A772FC.8020009@gmail.com>

I have added floppy write support, full hard disk emulation, and proper handling of DMA page faults to FreeBee. I also fixed the floppy step commands, changed the "force interrupt" floppy command to generate a type 1 status, and changed the DMA address counter to reset to 3fff when a transfer completes (which is what Unix seems to expect - without it, the kernel says that the floppy isn't ready). The floppy, hard disk, and DMA page fault tests all pass. Initializing hard disks and floppies also works (the geometry for both is still fixed by the size of the image, though, and format commands only appear to succeed, but they don't modify the image). Unix still doesn't run, though (it hangs after reading some sectors from the floppy).

 #
 #
 # Instructions for use:
 #   Run 'make init' to create the required directories
 #   Add your source files to the 'SOURCES' list, and change the TARGET filename
 #   Set the desired build type and platform in the BUILD_TYPE and PLATFORM
 #     variables respectively
 #   Set your project type (C only, or C++) in the SRC_TYPE variable
 #   Add any libraries you need to link against to the 'LIB' list
 #   Run 'make'
 #
 # Object files are created in the 'obj' subdirectory, from source code in the
 # 'src' directory. Dependency files are created in the 'dep' directory from
 # the same source code the object files are created from.
 #
 # Supported targets are:
 #   all                 Build everything.
 #   update-revision     Increment the build number without building anything.
 #   clean-versioninfo   Delete src/version.h (will be rebuilt on the next
 #                       'make all').
 #   init                Initialise the build system for a new project.
 #                       WARNING: overwrites .buildnum and src/version.h.in!
 #   cleandep            Delete all dependency files.
 #   clean               Delete all dependency, intermediate and target files.
 #   tidy                Delete all dependency and intermediate files, leaving
 #                       the target file intact.
 #
 # If you want to reset the build number to zero, delete '.buildnum'. This
 # should be done whenever the major or minor version changes. Excluding
 # .buildnum from version control may also be a good idea, depending on how
 # you want your build numbers to work.
 #
 # The BUILD_TYPE variable contains the current build type. There are two
 # supported build types:
 #   debug       Debug mode - object files are compiled with debug information
 #               and the target is left unstripped.
 #   release     Release mode - object files are not compiled with debug info,
 #               and the target is fed through strip to remove redundant
 #               data.
 #
 # The PLATFORM variable contains the current target platform. There are two
 # supported platforms:
 #   linux       GNU/Linux with GNU Compiler Collection
 #   win32       Windows 32-bit with MinGW
 #
 # The EXTSRC variable is used to specify other files to build. It is typically
 # used to specify platform or build-type specific source files, e.g.
 #
 # ifeq ($(BUILD_TYPE),debug-memwatch)
 #   CFLAGS += -g -ggdb
 #   CPPFLAGS += -DMEMWATCH
 #   INCPATH += ./memwatch
 #   EXTSRC += memwatch/memwatch.c
 # endif
 #
 # (example taken from one of my projects that allowed the use of Memwatch to
 #  track down memory allocation/deallocation bugs)
 #
 #
 # Change history:
 #   1.9 - Bugfix -- if CFLAGS contained a forward-slash, sed would fall over.
 #         Also added SDL support and fixed the date/time formats. To use SDL,
 #         set ENABLE_SDL to "yes".
 #   1.8 - Now supports the use of the wxWidgets GUI framework. To turn
 #         this on, set ENABLE_WX to "yes".
 #   1.7 - Now creates a basic Hgignore file and directory keepers for the
 #         dep and obj directories.
 #   1.6 - Added CFLAGS and CXXFLAGS to the command-lines for the dependency
 #         building commands. This was causing issues with C99 / C++0x mode.
 #   1.5 - Added support for Mercurial revision (changeset ID) display
 #         Fixed a few issues with Subversion support (svn: and version 0 would
 #         be displayed for exported code)
