Memory and file descriptor leak in QFontCache

Make the cache also use the ref counts
Make everyone who decrements a ref count check for 0 and delete
Move all cache logic to the cache
Same idea as 36cb3f3 and b3dae68 in Qt 5 without the extra stuff

Fix raster graphics on X11 RGB30

The window surface incorrectly assumes that any pixel depth of 24 or
above would be on 8bit/color. This breaks 10bit/color formats like
RGB30. This patch instead make it specifically check for color depth 24
or 32 which are the two with 8bit/color.

Fix QSysInfo::macVersion for OS X minor versions greater than 9.

gestaltSystemVersion's encoding only has room for a single version
digit. Thus, OS X 10.10 would previously have been detected as OS X 10.9

Cleanlooks style: Fix floating point exception

In QCleanlooksStyle::drawControl, if indeterminate == true and
rect.width() == 4, we will end up with slideWidth of zero, and
take a mod by zero when calculating the value of step.

This causes a crash in Quassel 0.10; see
https://bugs.gentoo.org/show_bug.cgi?id=507124

Instead, calculate slideWidth based on max(width, minWidth) where
minWidth was already set as 4, ensuring that slideWidth >= 2.
