Instead of immediately saving, which leads to poor performance,
and possible hardware damage (see #6057), limit saves to once
per second (similar to how KDE does it). It also guarantees
that only one save is required per second, by sharing a QSettings
object, and establishes a signaling framework to put other
setting save events into (but only uses this for the two major
offenders: playlist tab switching and window resizing).
This is in contrast to 6a312e7, which simply deferred the save
until program exit, and caused problems for some people (see #6217
and #6209).

Previously, the number of processes spawned was always
QThread::idealThreadCount() (returning the number of logical CPU
cores). On new systems with many cores, however, this can result
in 12, 16, 24, or ... processes being spawned, which is a bit
excessive.
This establishes a new config variable,
'max_numprocs_tagclients' within the Settings group, in order
to limit the maximum number of tag client processes that get
spawned. It also adds a means of setting this via the Behavior
page in Settings. It can be set to any integer in the interval
[1, QThread::idealThreadCount()]; it defaults to the maximal value
so as to emulate the old behavior.
QTimeLine duration must be greater than 0. If set to 0, a default of 1000ms will
be used. To avoid this, enforce a minimum of 1ms for pause and cross fade values
if those fades are enabled.
* Allow ignoring prefixes when sorting playlist
This introduces new configuration options which allow you to ignore
prefixes while sorting the playlist on album, artist and titles.
Prefixes are configurable, default are "a" and "the".
* Change QStringLiteral to QString for compatbility with Qt 4.8
This introduces new configuration options which allow you to ignore

- Disabling playlist row glow by default
- Track slider popup visible by default, add hide()
to ensure not visible by default (no more repaints)
- Set kTrackSliderUpdateTimeMs to 500. IMO 40 is too low
This should partially fix issue #1079
Any access, read or write, via QSettings requires locking
`Clementine.conf`. On some devices, this can be slow. Moreover, it also
increases power use and wear on devices such as SSDs.
To improve the situation, defer QSettings updates until program close
for window resize, current playlist tab, and playlist geometry, i.e.
`PlaylistView::SaveGeometry`.
Also, limit `PlaylistView::LoadGeometry` to once per program run.
