The regression affected AGOS and maybe some others; specifically,
the real MidiDriver would have been deleted twice -- I previously
missed that the Engine instances takes care of freeing the real
MidiDriver, not the MidiPlayer wrapping it.
This commit should clarify the ownership of the real MidiDriver for
most pseudo MidiDrivers.

Many engines follow the advice in audio/midiparser.h and create a
"pseudo-MidiDriver" subclass. But MidiParser really only needs a tiny
subset of the MidiDriver capabilities, namely those found in
MidiDriver_BASE. So we try to subclass from that whenever possible; this
allows us to remove many stub methods, and enables further future
simplifications.
|

This in turn enables modifying MidiDriver_MPU401::close() to allow
it to be called on a midi driver that has not yet been opened.
The specific issue that triggered me to make these changes was a
crash-upon-quit in HUGO, caused by it instantiating a midi driver,
then encountering an error (missing hugo.dat) *before* having
opened the new midi driver; the general cleanup code then tries
to close the (not yet opened) midi driver -> kaboom
Also fixed some engines which were leaking MidiDriver instances.

Using the timer mechanism for just a simple counter is not just
overkill, its also inaccurate. When using a call frequency of x,
and waiting for y callbacks, the passed time will not be x*y.
The problem amplifies on slower platforms and/or fair thread
schedulers.
Use absolute times instead. Most notably, the walking speed of
the avatar is now smooth on android, but probably on all other
handhelds we support too.

The new code is simpler, avoids a potential buffer overrun
(by avoiding to to use a buffer in the first place), and
hopefully has slightly more sane matching properties.

* names now comply to our naming conventions
* the function computeStreamMD5AsString which computes the MD5
as a hex string now returns it as a Common::String
* add doxygen comments

This makes AGI quite a bit less noisy by default.

Bug #3017908: "AGI: No music with the new MIDI patch"

This is based on patch #3085298 "overflows in agi and parallaction".

Forward-ported from branch. Let's do this the easy way for now, even
if I'm not sure why the save dialog shows the autosave slot anyway.

We have to update cursor position, not just terminate the input
buffer. This makes Ctrl-C work as intended, which fixes one half of
bug #3054184 ("SQ1 AGI: keyboard special keys are not functioning
properly"). I'm not sure if the second half actually is a bug.

The initial screen color needs to be 0 and not 0xf for these. Winnie C64/Apple II should be completable now, with some graphical glitches and palette problems.

This was due to a loop in AgiEngine::selectItems(int n), which lacked a check
that the engine was quitting or restarting.

(After a brief discussion with sev.) AdLib is now the old Sarien sound,
PCjr is the new PCjr emulation. PCjr is still the default; we don't
need to ask getMusicType() how to get there.

Music drivers:
default: proper Tandy/PCJr
adlib: proper Tandy/PCJr
pcjr: old Sarien emu
amiga: old Sarien emu in Amiga mode
pcspk: Sarien emu in PCSpk mode (quite wrong)
midi: 4 channel MIDI

Our warning() and error() functions always add an exclamation mark

Because chanGen() gets called very early, and sometimes it crashes
ScummVM as soon as the game starts. Actually, it's probably enough to
initialise a couple of fields in _tchannel[], but I figured it
couldn't hurt to clear all of _channel[] and _tchannel[].

This is currently done in the engine code. I adapted AGI, AGOS, DRACI,
GROOVIE, LURE, MADE, QUEEN, SAGA, SKY, TINSEL and TOUCHE to send a reset
device on startup. The sound output still works fine (started up a game
from every engine), so this should hopefully not introduce any regressions.
As far as I can tell it seems that SCUMM does send a proper device reset, so
I did not touch it. KYRA only sends a proper reset for MT-32 currently. I am
not sure about SCI though.
This fixes bug #3066826 "SIMON: MIDI notes off when using RTL after SCI".

Formerly the AGI MIDI code did not setup the channel mask properly, in case
"native_mt32" was set. This resulted in one missing channel (i.e. channel 0),
since the MT-32 only responds to data for channels 1-9.

Bug #3034370: "Manhunter: New York keyboard unresponsive". Actually
the keyboard was made responsive after June implementation of set.key,
still the game speed was increasing. Fixed that too.

Bug #3017911: "AGI (Fan): SQ0 - Ego flickering". It is a regression from r49745,
as it appeared, some of the screen updates were too much.
