This reverts commit 615326be9b because it
breaks windows builds.

Region::fade_range emits a signal which will call
ARDOUR::Playlist::region_bounds_changed, which takes a WriteLock.
That resulted in a WriteLock with ReadLock held.
CC is already set to a string. (And if it ever should be None, we want
to handle that explicitly.)
(And #autowaf.display_msg handle Booleans just fine.)
The sub_config_and_use function recursed, but it also invoked
autowaf.set_local_lib , which however didn't do anything useful. The
HAVE_ defines are not used anywhere, and the AUTOWAF_LOCAL defines are
only used in autowaf.use_lib, which however isn't used anywhere.
Dropping these defines simplify the build environment and makes the
compiler command line half as long and thus makes debugging much more
manageable.

By default, the project name and version are set to noname and 1.0. To
change them, it is necessary to provide two additional variables in
the top-level project file
- and waf code inspection confirms that waf itself only will use the top
level APPNAME.
autowaf has no real shutdown functionality anyway. The automatic
shutdown function that could have been called wouldn't work anyway, as
it takes an argument.
The only reason it doesn't fail is that the top level wscript has no
shutdown handling and doesn't recurse to other scripts, so it is all
dead code.
It turns out that slightly older versions of ALSA create different "pretty"
port names for USB MIDI devices than slightly newer ones. The new versions
use names that match those seen on other platforms.
This means that to do port matching on Linux now requires a regexp
to match the possible alternatives. This matters much more for the LPP,
which has 3 input ports and 3 output ports, than it does for most devices
that have a single input and single output, and we can "find" the ports
just using simple string searching
The kissfft library changed its SONAME and how the various libraries
were organized, e.g. the functions for complex and real numbers aren’t
in separate libraries anymore.

when Session emits RouteAdded, each handler (editor, mixer, trigger pages etc) will
execute their callbacks in order. But Editor::add_routes() selects the routes too,
which triggers a PresentationInfo::Change signal. This is received by e.g. the Mixer
before it has even found out about the newly added stripables. This in turn
leads to severe confusion regarding the state of the selection in the mixer,
and potentially elsewhere.
So, just add a PresentationInfo::ChangeSuspender for the scope of the RouteAdde
signal emission
Initially thew new region has a length of zero (0:0). When
merging Notes from a truncated region (no explicit note-off)
those notes are lost:
"Stuck note resolution - end time @ 0:0 is before note on: @ 0:0"
Truncate (or split) a region so that a note is cut short:
```
Region [{<--Note-------->}]
```
becomes
```
Region [{<--Note--]
^ implicit note-off at region boundary
```
When combining this region with an empty Region after gap,
```
Region [{<--Note--] [ ]
```
the result should be
```
Region [{<--Note->} ]
```
For this reason, even without a gap between the regions,
the original note length must not be restored.
The result MUST NOT be the same as the original:
```
Region [{<--Note-------->}]
```
