For whatever reason, Sierra decided that the final patches would
go in the root directory for Phant2. The game disc includes
(different, older) patches for many of the same resources in the
PATCHES directory, and loading those instead makes the game not
always work quite right.

Upon investigation of Sound code across SCI32 games, it was
determined that there are actually (at least) 3 different
revisions, not just a single SCI2.1 version. This patch only
changes the parts of Sound code that are relevant to the correct
use of Audio32.
Fixes Trac#9736, Trac#9756, Trac#9767, Trac#9791.

Italian still needs to be fixed, but nobody seems to have access
to this version at the moment.
Fixes Trac#9772.

In SSCI, games could never start at tick 0 because the video
benchmarking code on game startup would take several ticks to
run. In ScummVM, where the benchmarking code is disabled, it
becomes possible for games to start at tick 0. This can break a
lot of kernel code, which uses tick 0 as a special value
indicating that a feature is not active. For example, in GK2,
the music at the start of the game will not fade in on systems
that are fast enough to start audio playback at tick 0, since
a fade start tick of 0 is used to indicate audio fade is disabled.
Fixes Trac#9830.

Calling to SciEngine::syncSoundSettings from GuestAdditions
recurses back into GuestAdditions, which is obviously not
desirable. Even when it didn't manage to cause infinite recursion
(as in SQ6 demo), it would make the UI behave in broken ways (e.g.
the +/- buttons on the music slider in SQ6 would not work because
the UI would just get updated immediately back to the closest
rounded value).

LSL7 originally came with music in two qualities in subdirectories of
the 'music' directory, 22s8 and 22s16. The gog.com release doesn't do
this and only ships the hq music in the root of 'music/'. This PR adds
it to the search path.
Closes gh-951.

More than one call to OSystem::updateScreen per frame on systems
with vsync ruins performance because the call is blocked until
the next vsync interval.
This also fixes bad rendering performance with the OpenGL backend.

_delayedRestoreGame is always set and cleared at the same time as
_delayedRestoreGameId, and _delayedRestoreFromLauncher is written
but never read.

This patch includes enhancements to the ScummVM integration with
SCI engine, with particular focus on SCI32 support.
1. Fixes audio volumes syncing erroneously to ScummVM in games
that modify the audio volume without user action (e.g. SCI1.1
talkies that reduce music volume during speech playback). Now,
volumes will only be synchronised when the user interacts with
the game's audio settings. This mechanism works by looking for
a known volume control object in the stack, and only syncing
when the control object is present. (Ports and planes were
researched and found unreliable.)
2. Fixes audio syncing in SCI32 games that do not set game
volumes through kDoSoundMasterVolume/kDoAudioVolume, like GK1,
GK2, Phant1, and Torin.
3. Fixes speech/subtitles syncing in SCI32 games that do not use
global 90, like LSL6hires.
4. Fixes in-game volume controls in SCI32 games reflecting
outdated audio volumes when a change is made during the game
from the ScummVM launcher.
5. Fixes SCI32 games that would restore volumes from save games
or reset volumes on startup, which caused game volumes to be
out-of-sync with ScummVM when started.
6. ScummVM integration code for audio sync has been abstracted
into a new GuestAdditions class. This keeps the ScummVM-
specific code all in one place, with only small hooks into the
engine code. ScummVM integrated save/load code should probably
also go here in the future.
Fixes Trac#9700.

This also fixes the display of the startup LCD message, which had
been delayed until after the sysex transfer was finished.

For whatever reason, this game uses a different global for
specifying the text speed.

1. Shift save numbers up/down for game scripts that rely on save
game numbers starting from 0 to work correctly
2. Add fake file operations to support KQ7 save games
3. Hide autosave games from native save/load list to match SSCI.

This may come back in the future to deduplicate some gfx code,
but SCI32 had two different inlined ways of doing coordinate
conversions with different rounding methods, so CoordAdjuster32
didn't get used when the graphics system was rewritten.
At the moment, SCI32 code uses the mulru/mulinc methods from
helper.h for scaling up/down coordinates.

Only cursor remains to be updated to go through GfxFrameout, and
then we can let GfxScreen go back to being SCI16-only.

We originally used hardcoded gameIDs and checked for CD-version.
Now the game option itself is checked for.
When it's available for the currently detected game, the option
is read, otherwise it defaults to false (same behavior as before).

This commit implements all of the known plane transitions from
SCI2 through SCI2.1mid games. Because kSetShowStyle is always
called indirectly via the Styler game script, it is difficult to
find all the places where transitions are used. As such,
transitions that appeared to never be used have been added as
stubs which will trigger a game crash with a message to report
what was being done, so any missed transition types can be
identified quickly and then implemented.

The subtitles in KQ7 were not finished and don't quite work right,
drawing off the screen and in weird positions. They could probably
be fixed with some aggressive script patching, but for now, they
are just disabled (as they are in the official release).
