dosbox-x: Update to 0.82.22

0.82.22
  - Added Normal2x render scalers so that 'force scaler'
    for 1x2 or 2x1 scalefactors works and you can scale
    up 320x200/640x200 VGA modes and 640x200 CGA modes
    by 2x.
  - Main window titlebar now reflects whether or
    not the debugger interface is active.
  - Debugger interface now flushes terminal input
    upon entering the debugger, so that keyboard
    input prior to entering the debugger is ignored.
  - Debugger mapper shortcut and menu item are now
    a toggle. Selecting once will enter the debugger
    and selecting again will resume emulation.
  - cycles=max now displays cycle percentage correctly
    instead of showing e.g. 100 cyc/ms
  - (Allofich) Note and ignore INT 33, AX=53C1 call
    for the Logitech CyberMan.
  - Fixed odd code addition that disabled (through
    the configuration) XMS, EMS, and UMB when
    booting a guest OS. This fixes a problem where
    those services are not available when rebooting
    back into the DOSBox-X shell from a guest OS.
  - CGA 640x200 and MCGA 640x480 modes fixed to
    have proper refresh rate when machine=mcga,
    instead of 140Hz.
  - MCGA horizontal active display register
    encodes N - 1, not N, according to real
    hardware register dumps.
  - INT 10h modes 2 and 3 updated set MCGA CRTC
    write protect bit, to match real PS/2 hardware
    behavior, and to unlock CRTC registers during
    mode set.
  - PC-98 VSYNC interrupt now fires at vertical
    retrace start (as documented) instead of at
    active display end behavior borrowed from
    DOSBox VGA emulation. This fixes "Tonight"
    by Swat.
  - Fixed mistake that placed N88 ROM BASIC stub
    (something specific to PC-98) in memory even
    in IBM PC/XT/AT emulation mode.
  - Fixed some callback slot leaks that can cause
    DOSBox-X to run out of callback slots if you
    reset the guest system too much.
  - Fixed invalid callback and errant interrupt
    handling during BIOS reset delay that happens
    if you use the keyboard shortcut to trigger
    system reset.
  - XMS emulation resets global enable and local
    enable state on XMS emulation startup to fix
    crashes related to inability to control A20 gate
    after system reset or DOS kernel restart.
  - Debugger "SM" command now accepts segment:offset
    syntax for memory location to write.
  - Fixed INT 21h AH=65h bug that returns DBCS table
    for AH=4h that should return filename uppercase
    table.
  - Configuration GUI property settings are now
    shown in a single column wide list with scrolling.
  - In the configuration GUI, help dialogs will now
    present the help text as a scrollable region if
    there is too much to fit on screen.
  - dosbox.conf mixer rate will now accept any
    sample rate from 4KHz to 192KHz instead of only
    fixed specific sample rates.
  - cascade interrupt ignore in service setting now
    accepts true, false, and auto. "auto" is now the
    default, and will choose true or false depending
    on machine type for correct emulation either way.
    It should no longer be necessary to add
    "cascade interrupt ignore in service=true" to
    your dosbox.conf every time you want to run a
    PC-98 game properly.
  - PC-98 FM board emulation will now load SOUND.ROM
    into segment CC00h if available, if FM board
    emulation is enabled.
  - PC-98 INT 18h AH=30h updated to return AH=05h
    AL=00h BH=00h if success, AH=00h AL=01h BH=01h
    if failure. This is needed to get Puyo Puyo 2
    to work, which for some reason fails if a call
    to set 15KHz mode works.
  - PC-98 LIO and SOUND BIOS entry points, while
    still not implemented, have been updated to
    print the name of the call according to an
    online reference.
  - DOS FCB rename now supports renaming the
    volume label as MS-DOS does.
  - Fixed bug that prevented proper DOS FCB rename
    if the FCB used to rename is extended.
  - FAT filesystem driver updated to also store
    updated volume label in the boot sector of the
    partition, as per MS-DOS FAT standards.
  - FCB create can now be used to set a FAT
    filesystem label. MS-DOS LABEL.EXE works
    correctly now.
  - FAT filesystem driver now allows LABEL command
    to change the FAT volume label of mounted disk
    images.
  - DOS kernel updated to support basic FCB methods
    of deleting/setting the volume label, at least
    on local folder mounts.
  - DOS kernel will now return the volume label of
    FAT filesystems mounted from disk images.
  - LABEL setting code fixed not to treat label as
    if an 8.3 filename.
  - LABEL is no longer a builtin shell command and
    appears on drive Z: as LABEL.COM
  - LABEL reimplemented to imitate MS-DOS behavior
    with regard to how it handles the command line.
  - File I/O checking and cleanup (Allofich)
  - Integrated commits from mainline (Allofich)
    - Handle errant IRQs as a real BIOS does. Also
    remove r3263 workaround, as it's no longer
    needed.
    - Fix flag behavior of several shift/rotate
    instructions, cause exceptions and fix
    potential 'pop ss' problems
    - Add support for Print Screen key and
    interrupt. In-game screenshot feature
    of Descent and Descent 2 now works.
