In the justification code, we unconditionally subtracted one
from the line_length, but then compared the result to 0 afterwards,
so we did not support when the line_length is 0 initially, which
can happen if it only consists of spaces (in which case
trailingSpaces will be non-zero and line_length will be zero.)
The fix is to bail out for both strings of length 1 and length 0.

The plain text edit's smart repaint logic in
QPlainTextDocumentLayout::documentChanged assumes that during a change inside
just one block, the block is in the state before the edit and a call to
layoutBlock() is going to bring it up-to-date. Then only a comparison of the
bounding rect - before and after - is going to allow for smart repaints.
The assumption of the layout being in the same state as before the edit got
broken by commit cc57a2e90f, which introduced
code to use a QTextCursor within a slot connected to QTextDocument's
contentsChange signal. The usage of the QTextCursor there ends up updating the
layout of the block ahead of time, breaking the assumption and therefore the
optimization, in the sense that during changes in the preedit that cause a
change of height / line count, the old bounding rect in
QPlainTextDocumentLayout::documentChanged and the new bounding rect will be the
same. This causes a repaint of only the edited block, missing repaints of the
following blocks, even though the line count effectively changed.
So what's causing QTextCursor to mess with the layout is the attempt of
updating the vertical movement x property. This patch inhibits the update,
marking it as dirty for initialization later. This means that slots connected
to this low-level signal cannot rely on the cursor's visual x position, but
that doesn't seem useful anyway and isn't required for commit
cc57a2e90f.

This patch fixes an issue when a font that was added with
QFontDatabase::addApplicationFont can not be removed any more.
The reason for that is that QFontconfigDatabase::addApplicationFont
adds the font to the FontConfig application set from where it
cannot be removed any more and is picked up every time the font database
is repopulated (e.g. after a call to QFontDatabase::removeApplicationFont).
This also fixes the QFontDatabase autotest which unfortunately does
not fail on linux, because it tries to add "FreeMono" (which in most
cases is already there as a system font). So this patch removes FreeMono
and adds LED_REAL as test font.

This patch fixes two issues that prevented the application font related tests
of tst_QFontDatabase from passing:
* The code for creating the font descriptor after the registration of an app font
with file name using CTFontDescriptorCreateWithAttributes must create a dictionary
with kCTFontURLAttribute as key and the CFURLRef pointing to the on-disk file as
value. Unfortunately the code mixed up keys and values in the dictionary.
* Registration of app fonts within QFontDatabase itself on Windows and Fontconfig
platforms works by QFontDatabase calling addApplicationFont on the platform db
after calling populateFontDatabase(). It assumes that addApplicationFont on the
platform db is capable of registering the font right away. This part was also
missing from the Mac implementation and this patch implements it by moving the
common registration code from a CTFontDescriptorRef out into a separate method,
called from populateFontDatabase() as well as addApplicationFont().
