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

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.

(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.

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".
svn-id: r52736
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.

* Remove _isAttached member var and isAttached method
* Engines now always call the onFrame method; whether it does
something is decided by the debugger class resp. its subclasses
* Make detach() protected instead of private, so that subclasses
can invoke it
* Remove _detach_now member var (call detach() instead).
* Rename _frame_countdown to _frameCountdown and properly
document it.
* Add more doxygen comments
* Cleanup
