Traditonell zu Weihnachten: Vice 3.8

* Changes in Vice 3.8
=====================

** general
----------

- added WIC64 support for C64,C128,SCPU64,VIC20
- virtual device (host directory) fixes (Scratch command correctly returns
  number of scratched files, Rename command produces "file exists" error if the
  destination file exists)
- added video capture in ZMBV format. This will produce lossless videos at correct
  emulated FPS.
- the old FFMPEG support was deprecated and is disabled by default. New experimental
  code was added that will work with external ffmpeg executable instead.
- reSID: fixed a Noise Init problem
- reSID: filter tweaks
- reSID: The 6581 saw+pulse waveform was wrong
- reSID: tweak shift register reset time for 6581
- reSID: 8580 Filter ringing fix
- reSID: 6581 filters: allow negative values for kVg-Vx
- made raw printer driver pass through all bytes 1:1
- Tape: changed default zero-gap delay from the rather weird (and way too large)
  value 20000 to the more sane 2500 which MTAP uses
- RS232: handle RI line in IP232 (requires updated tcpser, see
  ​https://github.com/go4retro/tcpser/pull/24.
  - Add option to invert the RI line. This should help to make some more obscure
    BBS programs work
- RS232: removed undocumented feature to use unix domain sockets when the first
  character of a rs232 device is a pipe character, and instead used pipes, like
  it will be done on windows too
- Drives: fixed 1571CR emulation
- Drives: allow up to 83 tracks for 3.5inch mechs
- Drives: fixed clock rollover in rotation code
- REU: fixed DMA access to C64 RAM at $00/$01
- Added PaperclipE, PaperclipSC, and Paperclip2 dongle support.
- Added woj userport joystick adapter emulation.
- provide fake sid hooks so hardsid can be used when fastsid is disabled
- Printer: new reworked emulation handles various CBM Printers: 2022, 4023, 8023,
  MPS801, MPS801, MPS803
- Printer: tweaked MPS page height, now allows print shop to print a greetings
  card on a single page.
- Printer: do not produce any output for non-printable codes
- Printer: when using the graphic output driver, only produce a new file when
  actually doing a formfeed.
- Build the list of available palette files at runtime, scan system path/dirs as
  needed. Also read extra info from the .vpl files. New palettes can now be just
  dropped into the data dir and they will appear in the UIs.
- allow color controls to be used with external palette and when no crt emulation
  is active.
- Added more realistic vicii color ram init code.
- CIA: shiftregister fixes
- CIA: fixed ICR timing/behaviour (This fixes the dd0dtest from the testbench)
- Support for ISA/PCI devices that were accessed via direct I/O was removed,
  since this would not work in any sane modern OS anymore. The affected devices
  are: parsid (windows), ssi2001 (all)
- Z80: OUT, OUTD, OUTI, OTIR, OTDR instruction fixes
- Fixed -initbreak reset so that the first instruction doesn't run

- configure: change `--with-zip-bin` to `--with-unzip-bin`
- remove the configure switch --with-readline/--without-readline.

- Do not build PDF docs unless --enable-pdf-docs
- Fixed macOS bindist. Probably doesn't work without code signing, however an
  attempt is now made to detect and use a signing identity.

** SCPU64 fixes
---------------

- Do not call dma or clock stretch functions when a dma is already going on,
  dma is done at 1mhz speeds.


** PET fixes
------------

- Implement some beam-racing timing improvements for models with and without CRTC
- Add a PET palette that approximates the slightly blue white of the 2001 model.
- Monitor: handle SuperPET 6809 banking correctly

- fixed Disassembly of 6809 instructions
- make  monitor D and M command see the same memory (as set by the monitor's
  "bank" command), while single step, breakpoints, cpu history and debug cpu
  trace see the memory as the cpu sees it at that time.
- fixed crash when using an invalid DOS command with @, documented limitations
  of the @ command

** cartconv fixes
-----------------

- better support for VIC20 cartridges


** petcat fixes
--------------

- Added new BASIC 65 keywords


** GTK fixes
------------

- Fixed saving monitor position and size and restoring on boot
- All numeric values are displayed in proper units
- make dropping files on the main window work like it did in winvice - hold
  shift to just mount a new disk.
- VSID: Look up STIL info for file passed on command line
- macOS: Use Command+W to close monitor window
- Open file manager to view directory containing vice.log, instead of opening
  vice.log with an editor
- Settings: remember directory/filename in load/save dialogs
- Speed up RAM init pattern view.
- Speed up CRT slider widgets.
- Settings dialog: try to keep consistent (slightly smaller) size of the various
  nodes in the dialog; the dialog should fit on a ~1024x720 display.
- Settings dialog: move host GPU rendering options to Display -> Host display.
- Settings dialog: rework drive settings to use dialog space more efficiently.
- Settings dialog: rework printer settings.
- Settings dialog: more consistent cartridge setting layouts.
- Rename "soft reset" to "Reset machine CPU".
- Rename "hard reset" to "Power cycle machine".
- Simplify custom hotkeys saving: using "Save" now saves the hotkeys as
  "gtk3-hotkeys-$EMU.vhk" in the user's configuration directory. The UI also
  indicates where the current hotkeys were loaded from (VICE-provided default
  hotkeys, configuration directory or custom location).
- Hotkeys Alt/Command+3-6 added to send formfeed to printers (3 = userport,
  4-6 = printer 4, 5 and plotter).
- Hotkey actions added to select VIC/VICII/TED border modes, no default hotkeys
  assigned.
- Hotkey action to toggle status bars split into "show-statusbar-toggle" and
  "show-statusbar-toggle-secondary" (x128 VDC only) actions.
- Add status bar LEDs to control SCPU Speed (labeled "turbo"), and JiffyDOS
  switches (xscpu64 only).

** SDL Fixes
------------

- Rename "soft reset" to "Reset machine CPU"
- Rename "hard reset" to "Power cycle machine"
- Show scrollbar-like indicators when not all menu items can be shown on the
  screen.
- Update UI to use the same syntax as the Gtk hotkeys files: old .vhk files
  generated by VICE 3.7.1 or earlier will not work anymore.
- Add default hotkey Alt+T/Command+T to toggle SCPU Turbo mode (xscpu64 only).
- Add menu item to toggle patching of the v1 Kernal to make the ieee-488
  interface work (xpet only).
- Add menu items to load either the normal or the German chargen (xpet only).


** Linux fixes
--------------

- change default user directory for `vice.log` and autostart disk images to
  adhere to $XDG_STATE_HOME (defaults to ~/.local/state/vice).


** macOS fixes
--------------

- fix scrolling in the monitor


** Windows fixes
----------------

- Add -no-direct-streams command line option on Windows. With -no-direct-streams
  the stream direction code that reconnects the standard streams stdin, stdout
  and stderr to VICE is not called. This will mostly be useful for debugging
  weird issues on Windows.
- fixed issues with mouse warping
- fixed loading of the opencbm- and libusb DLLs


** BSD fixes
------------
