refactor: Swap %Ld for %lld in all format usages

* %Ld is an undocumented alias for %lld in glibc.
* muslc doesn't implement it for this reason.
* While we will likely never drop %Ld support,
lets clean house and set a better example.

* Do not create converters if target format has wildcards
for the respective aspect.
* Put back tracing output.

* The AudioProducer now correctly handles late producer notices by ignoring
extra notices for buffers already scheduled.
* Also, the AudioSupplier/AudioReader classes now know their initial latency,
and the AudioProducer is now using that one to advertize its own initial
latency - this fixes late buffers on start, causing the latency to grow
too large.
* Cleanup here and there.

# fa1a1c29 20-Oct-2009 Stephan Aßmus <superstippi@gmx.de>

All sorts of refactoring with regards to the audio node and format setup. At
first I tried adding support for changing the format during running the node
connection, but later found out that this is not implemented in the system
mixer (it has this weird setting to allow input format changes, but if you
do this, the media_server will just crash, since the backend does not support
it yet). Also, the Media Kit documentation is extremely lacking in this regard.
I ended up re-establishing the node connection when the audio format is
supposed to change, just like it is already done for video. This means that
audio files now play with their native channel count and frame rate. But it
isn't so well tested yet, if 48 kHz for example introduce some clicks. The
channel count should not be a problem though, I've also tested that with some
movies and it works fine.

# fb3e35fc 22-Jan-2009 Michael Lotz <mmlr@mlotz.ch>

Fixing all headers/namespaces/name lookup problems that hinder a GCC 4.3.2
build. I sure hope that this doesn't break the build for anyone else.

# 0fc56ed5 30-May-2008 Stephan Aßmus <superstippi@gmx.de>

* Moved a bunch of non-primary interface classes into a new subfolder
"interface"

* Complete reimplementation of the playback engine using Media Nodes:
- Seeking video files does not appear to lockup the playback anymore, but
works on a frame accurate level even for keyframe based streams. There is
currently a problem with certain container formats, the audio track reports
a "Device Seek Error" in certain conditions. In that case audio goes silent,
and can be restarted by going back to the beginnings of the stream.
- Video overlays are now supported.
- It would be possible to connect the output of the MediaPlayer to other
applications or dormant media nodes.

* Known regressions:
- The volume slider has currently no effect anymore.
- Switching the audio track during playback has a known race condition and
can crash the player.
- The new engine is not as "light weight" as the old one. I tagged the
previous implementation in tags/components/mediaplayer-engine-v1. It does
not seem to have any noticable effect though.
