Instead of uniformly demote configurations with a non-matching audio
input count (using a penalty offset of 1000), also grade the
impreciseness of the configuration so that those with the nearest input
count are preferred. As for outputs, give a slightly higher handicap to
configuration with too many inputs with regard to the actual audio
inputs that can be fed to the plugin.
POLICY CHANGE: when only imprecise configurations are found the actually
selected one can be different (better) than before this commit.
Just make the code responsible for possible_in > 0 also handle
possible_in == 0 since it nearly does the same thing.
The only difference is that the possible_in == 0 case, by using
FOUNDCFG(), acted as if possible_in was audio_in. The consolidated code
uses FOUNDCFG_IMPRECISE which will add some penalty to the
configurations where desired_in == possible_in != audio_in.
There is thus a small POLICY CHANGE, but the selected configuration will
stay the same unless a better matching configuration is available.
Still no policy change, since when a configuration is chosen that would
have belonged to the second pass, then its penalty will be increased by
1000 and it will be selected only as last recourse.
Merge the cases in == -1 and in == -2 since those are both wildcards,
almost symmetric in the AU spec, and handled completely symmetrically by
the code here considering it accepts invalid or unspecified demands.
Also merge the cases in > 0 and in < -2 since they are handled exactly
the same as far as outputs are concerned.
No policy change
Instead of doing an initial loop for detection of exact matches, then
letting the following loop set \audio_out yet ignore its value, merge
the two loops but give exact matches a negative penalty so that the
\audio_out value they set won't change afterwards.
No policy change.
The reverb and chorus states in the fluidsynth object need to be initialized to
0 (false) in accordance with the initial state of a-fluidsynth's
v_port[...]. Otherwise they are not updated in the first run() and remain to
fluidsynth's default state 1 (true) even though the plugin's state requires 0.
The backend will replace the information in the last bracket (IO)
of the name with (In/Out) when creating pretty port-names from the
device-name. -- see replace_name_io().
This fixes an issue with device-name number suffixes in brackets.
Add support for smoothing, ignore message when controllers are
not in sync to avoid discontinuous jumps.
This is mainly useful for Mackie-like devices that use pitch-bend
messages for faders.

The engine setup identifies devices by name (device list is a map<>
with the device-name as key). To support multiple devices with the
same name, the name needs to be unique.
So far this is achieved by simply adding a number suffix starting with
the 2nd device (this allows to re-use configurations).
Ideally we'd use UUIDs or unique device IDs to handle this, and also
somehow clarify which device is which...
Assume the following connections
Audio -> Bus1 --aux-send--> Bus2
Prior to this commit, Audio -> Bus2 was marked as "direct feed",
even though the connection was only indirect via an aux-send.
This caused issues with implicit solo and could lead to stuck solo.
"last_controllable_value" is using midi value range (0..127).
It is used to compare received midi-value with the actual controllable
for non-motorized surfaces, and this change allows the first
event to already be in_sync.
Previously the first MIDI-event was usually ignored (because
last_controllable_value was out of bounds or didn't match the 0..127
range.
