When cloning a QTextDocument, the text fragment of the original document
is copied into the new one, which results into copying also the
formatting attributes. However, when the text document is empty, the
corresponding text fragment is also empty, so nothing is copied.
If we want to transfer the formatting attributes for an empty document,
we need to set them explicitly.

The code was assuming that if the parsing of the value worked,
then it must be a list of 4 variants. But in this case it's just
a single length.
This came from <td> using 4 values for border-width
while other elements use a single value. But the storage
is shared. So the fix is to use 4 values everywhere.
When reading 4 and there's only one, it gets duplicated,
so the caller can just use the first one in that case.

The markdown parser generates empty lists in some cases when a character
that can be used as a bullet is found on a line by itself.
cbEnterBlock() and cbLeaveBlock() are called symmetrically in such cases.
QStack::pop() on an empty stack triggers an assert, so push and pop need
to be done symmetrically too. But it's difficult to actually create the
list as soon as the MD_BLOCK_UL or MD_BLOCK_OL callback occurs, without
breaking the case fixed in 7224d0e427 (and
probably other cases). That's because QTextCursor::insertList() creates
a list item at the same time as it creates the list itself, and also
inherits block formatting from the previous block. We now insert empty
lists with empty items whenever the need for that is detected though,
and there's a failsafe to prevent popping in case something still goes
wrong with that logic. We aren't strict about reproducing the original
markdown when regenerating it via toMarkdown(), but it's getting closer.

If a font with only a family set is resolved with one that has been setup
with setFamilies() then the family needs to be prepended to the families
list after resolving. This is so that the font still prefers the one set
as just a family with no famillies set.
This also amends the QFontDialog test to account for this too.

Notes:
The QTextDocument table model is much simpler than the HTML table model.
It basically only has <table> and <td> support. So the HTML parser is
forced to map markup and styling to the QTextDocument model which
is not without loss.
In other words: While QTextDocument -> HTML -> QTextDocument should
preserve the QTextDocument structure, HTML -> QTextDocument -> HTML
does not preserve the HTML DOM at all.
So for now the HTML importer and writer only support border styles on
the <td> and <th> nodes. In future updates, the HTML parser might be
enhanced to map <tr> and <table> CSS styles to the cells.

When calling QTextDocument::clearUndoRedoStacks() with UndoStack,
there were two bugs: The first was that we were retrieving
the item at "undoState" and deleting this. This is actually the
upper limit of the for loop. If the stack does not contain any
redos, then it would be == undoStack.size() and we would assert.
If there were redos, then we would delete the item at undoState
multiple times (actually undoState times).
In addition, when the loop exited, we first removed the dangling
pointers using remove() and then there was a weird resize() to
the new size minus the old undoState.
This would either assert because we tried to resize to a negative
number, or it would arbitrarily remove items from the stack.

When combined with 97f73e9577,
this caused an error, because the code in
QFontEngineMulti::loadEngine() only overrode the families
list, but not the singular family in the request. In the
QRawFont test, this would cause the requested fallback font
to correctly have "MS Shell Dlg2" as the only font in the
families list, but the request.family would still be
"QtBidiTestFont", the name of the main font. The singular family
in the request was preferred by the windows font database when
creating the LOGFONT. We would therefore load the latter for
the fallback as well and since it still does not support the
characters in question, we would continue searching.

When eliding text we would check for the existence of the ellipsis
character and fall back to using the dot if it was not available.
However, when font merging was in use, we would also use ellipsis
from a fallback font if available. This could cause the metrics
of the text to increase if the fallback font had larger metrics,
and the result was that text could shift when elided.
It is better to prefer the dot from the current font than to use
the ellipsis from a fallback, so we only use the ellipsis if
it is in the main font.
