dosbox-x: Update to 0.82.23

Changes:

  - Serial and parallel file output now disable stdio
    buffering so that output is more immediately
    accessible to the user.
  - Added file output to serial port emulation.
  - Parallel port emulation now support both dev: and
    file: to specify that LPTx output go to a file,
    not necessarily a device by name.
  - Fixed bug that capped vmemsizekb to 8KB.
  - BIOS bootup screen now shows correct text for CPU
    type instead of "? CPU" when cputype=auto.
  - PC-98 256-color mode fixed to ignore doublescan
    and 200-line bits of the GDC to match real hardware
    behavior. This fixes display problems with
    "Alone in the Dark"
  - BOOT command will now always set 640x200 8-color
    graphics mode when booting PC-98 disk images,
    to match the apparent behavior of real hardware.
  - PC-98 hardware apparently allows writing port 6Ah
    to jump directly to 256-color mode from 8-color
    mode, update DOSBox-X emulation to allow it.
    This fixes the PC-9821 port of "Alone in the Dark".
  - Slow CGA memory access handler now wraps to 16KB
    correctly, and resolves a segfault that can happen
    if the last 16KB is accessed by the guest if
    vmemsizekb=16.
  - vmemsize default is now -1, which means to pick a
    video memory size automatically.
  - Added PC-98 INT 1Bh AH=03h SCSI BIOS command, which
    allows FreeDOS98 to boot.
  - INT 33h emulation fixed not to reset mouse min/max
    range if the new video mode is a VESA BIOS SVGA
    mode (not a standard VGA mode). Some games seem to
    define the mouse min/max range AND THEN set the
    VESA BIOS mode, not the other way around.
  - INT 33h define range functions now apply rounding
    to the max range if the range is close to the
    dimensions of the screen, for games like Daggerfall
    that set the cursor maximum range to values close to,
    but not exactly, the dimensions of the VGA screen.
  - INT 33h define range functions updated to accept max
    ranges for mapping host to guest if set just after
    video modeset or if those INT 33h functions are called
    when no mouse buttons are down.
  - INT 10h AH=4Fh AL=08h (Set DAC width) now correctly
    set AL=4Fh to indicate the call is supported.
  - VGA DAC palette writes are now ALWAYS masked to 6-bit
    unless 8-BIT DAC mode is ON and enabled. This fixes
    palette problems with Amulets and Armor.
  - VGA DAC 6/8-bit palette management code simplified
  - Added dosbox.conf option to instruct DOSBox-X to leave
    the PC speaker clock gate enabled if set, for games
    that use that PIT output as a time source. Setting
    the option to "true" allows "Bàoxiào sānguózhì", a game
    with strange and elaborate timing code, to run without
    hanging at the second title screen.
  - VGA port 3DAh "undefined bits" setting changed to 0x04
    to accomodate "Blues Brothers"
  - Configuration GUI: If the settings are scrollable,
    tabbing between fields will now auto-scroll to the
    field and make it visible.
  - In the configuration GUI, scroll wheel input no longer
    changes the window focus.
  - Set CPU cycles dialog box layout fixed.
  - Added 'skip encoding unchanged frames' option to
    dosbox.conf. If set, AVI video capture will skip
    video frame compression if the frame has not changed
    from the previous frame. Option is off by default
    at this time in case it causes any issues with users
    and their video editing software.
