94aed0be1f Use "und" in place of HB_LANGUAGE_INVALID.
Buffers with HB_LANGUAGE_INVALID race since it will force
hb_buffer_guess_segment_properties to call hb_language_get_default which
is not thread safe. The user is required to pass a language string to
the shaper, but it may be malformed and hb_language_from_string may
return HB_LANGUAGE_INVALID. Detect this and use "und" as the language,
since the language really isn't known (RFC5646 4.1 5).

d13487e71b Regularize SkFontMgr for CoreText build.
Move SkFontHost_mac.cpp into an 'optional' like the other fontmgr build
rules. This allows building with other fontmgrs on Mac and makes the lib
dependencies explicit. In the future this helps with splitting the out

5b8dd73546 Hide ICU C++ API from Skia users.
Parts of third_party need the C++ API so hide it from Skia users as
needed to prevent re-introduction.

This also avoids the ICU version renaming / name mangling when building
our own test version of ICU. This makes life in an editor and debugger
much easier.

96f6401789 harmonize rewrite-includes and gn-format checks
The CheckGeneratedFiles bot only required rewriting
.gn files, while the presubmit wants both .gn and .gni files.

It also appears that the #includes rewrite script runs on
both the presubmit and CheckGeneratedFiles bots.

These presubmits run on the CQ before landing right?
If so, no need for them in the CheckGeneratedFIles bot at all.

And of course, format .gni files.

This serves as the model for that. Doing this with other modules will

32b45b32b7 Glyph 0xFFFF is a valid glyph.
Assert that the hb_codepoint_t passed to skhb_glyph_extents is in range
using SkTo, which is obviously correct (and consistently used elsewhere)
instead of the incorrect '< 0xFFFF' since 0xFFFF is a valid glyph id.

While doing so, rename the hb_codepoint_t parameters which are actually
glyph ids to reflect that they are glyphs and not codepoints (HarfBuzz
uses hb_codepoint_t for both).

56a48bb1aa Avoid BOT/EOT setting in HarfBuzz.
Unlike many users of HarfBuzz, the Skia shaper sets HB_BUFFER_FLAG_BOT
and HB_BUFFER_FLAG_EOT flags to inform HarfBuzz that the full context
contains the beginning and end of the paragraph so that it can treat the
beginning and end of the context specially. In reality, the EOT flag
currently does nothing and the BOT flag only has the effect of adding a
dotted circle (if the font provides it) if the first codepoint in the text
and context is a unicode mark. This behavior is generally unwanted, so
just remove it with a note to revisit this decision should HarfBuzz ever
change the effect of these flags.

1ca50524c4 Allow better font fallback.
The intent is to allow the creation of a MakeFontMgrRunIterator which
uses the passed font's typeface as the primary typeface, but uses a
given family name and style as for the request for fallback fonts. This
allows the user to provide the actual request for the primary typeface
as opposed to making a request based on the resolved primary typeface
(which may not be the right thing to do).

To support this, the selection of language for fallback is also added.
Since this information is already in the language iterator, this change
makes the font iterator the lowest priority iterator for consume,
allowing the font iterator to rely on the current value of the language
iterator to provide the language.

In order to allow these changes to be exercised, this also adds a few
generic 'Make' methods for bidi and script. These new methods will use
the best available implementation. These are needed since the most
capable implementations may not always be available (such as on our
testing ios builds).

723a877d0c Make SkFunctionWrapper a better wrapper.
SkFunctionWrapper was made to be a simple abstraction over existing
resource release functions which generally follow a specific pattern of
returning void and taking a pointer to the underlying type. However,
this has been observed to be an unnecessary limit. This makes it more
generic while also making the call sites a little less brittle.

This change also uncovered an issue in msvc v19.20 to v19.22, see
https://developercommunity.visualstudio.com/content/problem/698192/in-templateusing-decltype-is-void.html
To work around this, several otherwise redundant '&' are used.

There was an attempt to take references to functions instead of pointers
to functions which greatly simplifies the intermediate wrappers.
However, that uncovered another issue in msvc, see
https://developercommunity.visualstudio.com/content/problem/699878/function-to-pointer.html

bedbb0780b Allow HarfBuzz to massage the character stream.
If the nominal_glyphs callback returns a value less than 'count'
HarfBuzz will process the rest of the buffer with the nominal_glyph
callback and attempt to find glyphs through NFC and space synthesis. It
may be preferable in the future to tweak this behavior, since this is
effectively modifying the font.

426843323f [skottie,skshaper] Plumb an optional SkFontMgr in SkShaper/SkottieShaper
Skottie already takes an optional client fontmgr at load time, but
SkShaper(HB) currently uses the default fontmgr for fallback.

Plumb the Skottie font manager all the way to SkShaper.

This should give clients more control over font fallback, instead of
relying on the default SkFontMgr.

requires this to be overly clever. Perhaps a better solution can be
