We protect the shaped-word cache in each font with a RWLock, so that multiple threads can
shape in parallel using cached data; only when a new entry needs to be cached will we need
to take a write lock.
(To improve clarity, this patch also constifys a bunch of methods that do not mutate the
font instance.)

This tries to clean up some of the awkwardness from bug 1730772 so that we can
do further fixes more easily if necessary.

Note that this patch only transforms the use of the nsDataHashtable type alias
to a directly equivalent use of nsTHashMap. It does not change the specification
of the hash key type to make use of the key class deduction that nsTHashMap
allows for in some cases. That can be done in a separate step, but requires more
attention.

This allows us to avoid instantiating separate gfxFont objects when content is tagged
with different 'lang' attributes, yet ends up using the same fonts (e.g. Wikipedia may
use a default font such as Arial for language names/links that are tagged with several
dozen different languages).

This removes a lot of old cruft in thebes to instantiate Cairo scaled fonts.
Instead, we only instantiate the Cairo scaled font inside Moz2D when we actually
need it for DrawTargetCairo. This thus gets rid of the duplicated code we had
inside both Moz2D and thebes to deal with Cairo scaled fonts.

* Remove redundant virtual keywords
* Mark all destructors of inheriting classes as virtual for clarity
* Mark all classes without virtual destructor as final (exposed errors)
* Make destructor virtual where it needed to be (some were missing)
* Replace empty ({}) code declaration in header with = default
* Remove virtual unused methods
I probably missed some, it quickly became a rabbit hole.

With bug 1509358 having landed we don't need a draw target in a bunch of
places. This removes it from those places.

This rearranges how synthetic-bold use is determined in the font selection
& rendering code. Previously, we would decide during the font-selection
algorithm whether we need to apply synthetic-bold to the chosen face, and
then pass that decision through the fontgroup (storing it in the FamilyFace
entries of the mFonts array there) down to the actual rendering code that
instantiates fonts from the faces (font entries) we've selected.
That became a problem for variation fonts because in the case of a user
font, we may not have downloaded the resource yet, so we just have a "user
font container" entry, which carries the descriptors from the @font-face
rule and will fetch the actual resource when needed. But in the case of a
@font-face rule without a weight descriptor, we don't actually know at
font-selection time whether the face will support "true" bold (via a
variation axis) or not, so we can't reliably make the right decision about
applying synthetic bold.
So we now defer that decision until we actually instantiate a platform font
object to shape/measure/draw text. At that point, we have the requested
style and we also have the real font resource, so we can easily determine
whether fake-bold is required.
(This patch should not result in any visible behavior change; that will
come in a second patch now that the architecture supports it.)
AutoTextRun now only needs a DrawTarget instead of an nsRenderingContext, and
similar nsRenderingContext/gfxContext-to-DrawTarget replacements can be
propagated a long way up the call graph. This patch replaces 93 occurrences of
nsRenderingContext and 135 occurrences of gfxContext with DrawTarget; that's
13% of them.
The patch is mostly plumbing changes. A couple of not-entirely-plumbing
changes:
- It adds a comment about the null check in
gfxGlyphExtents::GetTightGlyphExtentsAppUnits().
- A couple of functions simply had an unused gfxContext or nsRenderingContext
parameter removed, e.g. SetLineBreaks().
