Being a most significant method in the font API,
getSfntTableData() must behave in exactly the same way on all platforms.
Briefly, it must return true if the table exists in the font,
despite the other params, and always stores the table data length
in 'length' param, thus reporting the amount of bytes actually
needed to store the table data in a buffer.

Change 4b2c73b4767bcb512cbc17f65186eac5d004db07 triggered a
regression on Android, because the DroidSansFallback.ttf font
has codepage ranges that list Arabic as a supported codepage
despite the fact that the font has no glyphs for Arabic.
If a font has valid unicode ranges which does not specify
support for e.g. Arabic, then the code page ranges for the
same script should be ignored.
[ChangeLog][Android][Fonts] Fixed support for Arabic text.

Commit f4dd534 introduced a regression, so that QFontMetrics reported
a wrong size (to be more specific width) for FreeType fonts.
The calculation of glyph advances has to to reflect (rounded)
integral number of pixels. This was only done when the glyph was cached.
So in some cases the first call to QFontMetrics::size gave a different
result than the second.
This patch reverts f4dd5344fbbce257a40e014acc4e87f4773f40.
The tst_QFontMetrics::same auto test only happened to work on some
platforms, on BlackBerry for instance it did not. Extended the test
case to make sure it works for different font sizes.

Instead of the glyph cache having its own cache type that always mapped
one to one to a font engine glyph format, causing confusion and needless
conversions, the glyph caches now use QFontEngine's glyph format enum.
This also removes the iffy use of an int for the glyphFormat in the font
engines.

The properties that make up the hash value are chosen to be the same as those
that make up QFontDef's op<() and op==(). Indeed, the implementation for QFont
simply delegates to the one of QFontDef, which has been added for this purpose,
but may prove useful in its own right down the line.
The code would greatly benefit from a qHash(qreal) implementation. Lacking
this, the patch uses multiplication with 10000 and qRound64() to convert
the one floating-point property used in the hash to an integer. This is
probably the right thing to do anyway, to avoid epsilon problems.
[ChangeLog][QtGui][QFont] Added qHash overload for this class.

The HB face caching mechanism introduced in 227e9a40cfeb7e00658cd3
wasn't complete due that fact that HB-NG doesn't parse the entire
font table at once but rather references a table on-demand.
This incompleteness caused a crash in case the engine doesn't
get cached or when it removed from the cache and then re-used.

Qt would see the end of <span>, and consider the current block
tag as closed, thus resetting the block format, thus losing the
margin set for the current block (due to blockquote).
If you do

</blockquote>
instead, then the same would not happen, since hasBlock is set
