We have to lock Mixer when touching Song's state via Song::startExport()
and Song::stopExport() in ProjectRenderer::run() as the FIFO writer
thread may call Mixer::renderNextBuffer() (which calls Song::doActions())
simultaneously. Fixes a random segfault when exporting project.
This was a new bug as the ProjectRenderer does not operate FIFO-less
anymore.

There's no need to start the ProjectRenderer thread with high priority
anymore as the actual rendering is done on the other side of the FIFO.
The ProjectRenderer just waits for new data in the FIFO and encodes
them as they arrive.
Renamed the ProjectRenderer::OutputSettings structure to
ProjectRenderer::EncoderSettings to better reflect its meaning.
Additionally added some basic Doxygen comments.
Until now, Mixer not only was responsible for rendering audio buffers
but also managed writing them to audio backend (through a FIFO) and
handled various quality related parameters.
All this functionality has been moved into the new AudioOutputContext
class. It glues together AudioBackend (formerly called AudioDevice),
global quality settings and the Mixer.
The AudioOutputContext class creates a FifoWriter which calls
Mixer::renderNextBuffer() and writes the output into the BufferFifo of
the AudioOutputContext it belongs to. The BufferFifo is read by the
according AudioBackend which belongs to the AudioOutputContext as well.
The AudioOutputContext also handles resampling in case the AudioBackend
wants the buffers in a different samplerate.
During this rewrite the Mixer class and the according source files have
been renamed from "mixer" to "Mixer". This results in small changes
all over LMMS' code base.
This reverts commit c517f1fa5a.
The commit was not very helpful and introduced new xrun problems.
Instead I'll be rewriting the part of LMMS where Mixer, Mixer's
quality settings, Buffer FIFO and AudioDevice are sticked together.
There's really no need to allocate a buffer each period, push it to the
FifoBuffer and free it when fetching the buffer in
AudioDevice::getNextBuffer(). Instead keep the pointer in FifoBuffer's
pool and reuse it.
Try to adjust latency of PulseAudio according to our settings of mixer
so it does not have such a bad latency anymore.
Furthermore force PulseAudio to play silence instead of rewinding
streams in case of underruns.
There have been some problems with the threading logic in the
AudioPulseAudio backend resulting in an endless loop when quitting LMMS.
Furthermore allocated PulseAudio resources were not freed properly.
Thanks to Armin Kazmi <armin.kazmi@tu-dortmund.de> for pointing out
this issue.
every time auto-save ran, it would change the current project to
"recover.mmp". Now it doesn't do this because Song has
guiSaveProject(), guiSaveProjectAs(), and saveProjectFile().
(the latter is used for auto-save)
Changes in base directory were not tracked by filesystem watcher.
Explicitely add base directory to filesystem watcher and add a special
case to LocalResourceProvider::reloadDirectory().
When customizing background color of a widget via CSS, Qt somehow
falls back to ugly old windows style. This resulted in ugly looking
scrollbars in WelcomeScreen when working at a low screen resolution.
Therefore disable those scrollbars as they're rather useless anyways.
QListView automatically shows three dots for too wide text items.
auto-save time is not configurable yet. saves "recover.mmp" to
WORKING_DIR every 60 seconds. Deletes recover.mmp on successful
close of LMMS. If recover.mmp is found upon start, it loads that
project.
