Also gate them behind the presence of a 184.VOC resource instead of GID_CATDATE. This should not matter with regards to the remap effects -- the 2015 and 2016 demos had none, and the first that did has an unknown release status. Only the 2017 demo would fall, which would be easily fixed by dropping in a valid 184.VOC patch file.

This code is currently untestable and is almost certainly at least
partly based on guesswork & not actual reverse-engineering (as was
the case for all other pre-2015 SCI32 code), so future developers
interested in adding SCI32 Mac support should use it only as an
intermediate reference rather than as known good code.

This changes the syntax for bpk and logkernel:
Enable breakpoint on kernel call:
bpk FrameOut
Enable logging for kernel call:
bpk FrameOut log
For backward compatibility this has an alias: logkernel FrameOut
Removing a kernel call breakpoint is done with bp_del/bc now.

Hoyle5 will spin on kGetTime between 15 and 300 ticks in multiple
game scripts in order to delay execution (for example, after
choosing opponents and clicking "okay"). This causes ScummVM to
be unresponsive and wastes CPU time.
This commit patches the spin subroutines to instead call a kernel
function (kWait) that waits without a spin loop. This kernel
function was removed in SCI2, and has been added back in ScummVM
specifically for Hoyle5, so this patch will not work with the
original interpreter.

SCI3 includes four new opcodes:
* op_info[0x26][0] puts -info- flag in accumulator
* op_infoSP[0x26][1] pushes -info- flag to stack
* op_superP[0x27][0] puts -super- reference in accumulator
* op_superPSP[0x27][1] pushes -super- reference to stack
The implementation of these opcodes was correct already, but the
opcode names given were a bit misleading (the value is not always
stored to accumulator), and magic numbers were used for these
opcodes in places.
A review of the opcode table in Phant2 indicates that there are
no other new opcodes for SCI3.

This change invalidates earlier SCI32 save games, which separated
arrays and strings in an incompatible manner. Old save games
contain invalid references to a string segment which no longer
exists, and contain incompatible array structures that lack
critical type information.

LSL6hires calls 0x23 (Graph/Robot) from game scripts, but it is a
null function in the game's interpreter.

ExecStack now stores the kernel call number as well as the subfunction.
This allows kStub and backtraces to log the actual subfunction called.
The kernel call number in ExecStack used to be stored in the
debugSelector field. It now has its own field, to avoid confusion.

The demo versions of these games were using a very different engine -
SCI1.1 vs SCI2/SCI2.1. Thus, we split them into different game IDs,
to avoid mixing specific game checks for them, as well as specific
game workarounds, which are different for the demos than the full
versions. Also, the demos should be working when SCI32 is disabled.
For these games, we don't use ADGF_DEMO, to avoid game IDs like
foodemo-demo

Instead of choosing Windows as platform, users can now also simply
click this option for Gabriel Knight 1 + King's Quest 6
Defaults to high resolution graphics

(didn't work since the introduction of kString signatures and the
kString split-up)
|
|
- Detection works via signatures (couldn't find a better way)
- new kString subcalls were introduced SCI2.1 LATE
- kString now has signatures and is split via subcall table
- kString fix, so that KQ7 doesn't crash, when starting a chapter
- Sci2StringFunctionType removed, because no longer needed

"PC" was very ambiguous and now it matches what we show in the GUI.
This also corrects sword2's platform to Windows.

No functionality change has been made with this commit. This avoids
setting and getting the reg_t members directly, and is the basis of any
future work on large SCI3 scripts (larger than 64KB)

This reverts commit 577d7e41c9ca2c498dc85e41c373fbdca8d2ed41.

This is needed for upcoming changes to the Script class

SCI scripts can send stale pointers to kernel functions (e.g. after
loading a saved game). This is normal in some cases (such as kDisplay
and kGraphRestoreBox), and their signatures are set to allow invalid
pointers.
Thus, in such cases, allow invalid pointers, as the kernel functions
will handle them themselves. Fixes bug #3412002, and properly fixes bugs
#3389579, #3292251, #3308087 and #3056811. Removed a relevant TODO.
