592c507248 harfbuzz: Update to version 4.4.1 
- Update from version 4.2.0 to 4.4.1
- Update of rootfile
- Changelog
   Overview of changes leading to 4.4.1
	- Fix test failure with some compilers.
	- Fix Telugu and Kannada kerning regression.
   Overview of changes leading to 4.4.0
	- Caching of variable fonts shaping, in particular when using HarfBuzz’s own
	  font loading functions (ot). Bringing performance of variable shaping in par
	  with non-variable fonts shaping. (Behdad Esfahbod)
	- Caching of format 2 “Contextual Substitution” and “Chained Contexts
	  Substitution” lookups. Resulting in up to 20% speedup of lookup-heavy fonts
	  like Gulzar or Noto Nastaliq Urdu. (Behdad Esfahbod)
	- Improved ANSI output from hb-view. (Behdad Esfahbod)
	- Support for shaping legacy, pre-OpenType Windows 3.1-era, Arabic fonts that
	  relied on a fixed PUA encoding. (Khaled Hosny, Behdad Esfahbod)
	- Sinhala script is now shaped by the USE shaper instead of “indic” one.
	  (Behdad Esfahbod, David Corbett)
	- Thai shaper improvements. (David Corbett)
	- hb-ot-name API supports approximate BCP-47 language matching, for example
	  asking for “en_US” in a font that has only “en” names will return them.
	  (Behdad Esfahbod)
	- Optimized TrueType glyph shape loading. (Behdad Esfahbod)
	- Fix subsetting of HarfBuzz faces created via hb_face_create_for_tables().
	  (Garret Rieger)
	- Add 32 bit var store support to the subsetter. (Garret Rieger)
	- New API
	   +HB_BUFFER_FLAG_DEFINED
	   +HB_BUFFER_SERIALIZE_FLAG_DEFINED
	   +hb_font_changed()
	   +hb_font_get_serial()
	   +hb_ft_hb_font_changed()
	   +hb_set_hash()
	   +hb_map_copy()
	   +hb_map_hash()
   Overview of changes leading to 4.3.0
	- Major speed up in loading and subsetting fonts, especially in
	  handling CFF table. Subsetting some fonts is now 3 times faster.
	  (Behdad Esfahbod, Garret Rieger)
	- Speed up blending CFF2 table. (Behdad Esfahbod)
	- Speed up hb_ot_tags_from_language(). (Behdad Esfahbod, David Corbett)
	- Fix USE classification of U+10A38 to fix multiple marks on single Kharoshthi
	  base. (David Corbett)
	- Fix parsing of empty CFF Index. (Behdad Esfahbod)
	- Fix subsetting CPAL table with partial palette overlaps. (Garret Rieger)
	- New API
	   +hb_map_is_equal() (Behdad Esfahbod)
   Overview of changes leading to 4.2.1
	- Make sure hb_blob_create_from_file_or_fail() always returns nullptr in case
	  of failure and not empty blob sometimes. (Khaled Hosny)
	- Add --passthrough-tables option to hb-subset. (Cosimo Lupo)
	- Reinstate a pause after basic features in Khmer shaper, fixing a regression
	  introduced in previous release. (Behdad Esfahbod)
	- Better handling of Regional_Indicator when shaped with RTL-native scripts,
	  reverting earlier fix that caused regressions in AAT shaping. (Behdad Esfahbod)

f5ebb58ab4 harfbuzz: Update to version 4.2.0 
- Update from 3.4.0 to 4.2.0
- Update of rootfile
- Changelog
   Overview of changes leading to 4.2.0
     Wednesday, March 30, 2022
	- Source code reorganization, splitting large hb-ot-layout files into smaller,
	  per-subtable ones under OT/Layout/*. Code for more tables will follow suit in
	  later releases. (Garret Rieger, Behdad Esfahbod)
	- Revert Indic shaper change in previous release that broke some fonts and
	  instead make per-syllable restriction of “GSUB” application limited to
	  script-specific Indic features, while applying them and discretionary
	  features in one go. (Behdad Esfahbod)
	- Fix decoding of private in gvar table. (Behdad Esfahbod)
	- Fix handling of contextual lookups that delete too many glyphs. (Behdad Esfahbod)
	- Make “morx” deleted glyphs don’t block “GPOS” application. (Behdad Esfahbod)
	- Various build fixes. (Chun-wei Fan, Khaled Hosny)
	- New API
	   +hb_set_next_many() (Andrew John)
   Overview of changes leading to 4.1.0
     Wednesday, March 23, 2022
	- Various OSS-Fuzz fixes. (Behdad Esfahbod)
	- Make fallback vertical-origin match FreeType’s. (Behdad Esfahbod)
	- Treat visible viramas like dependent vowels in USE shaper. (David Corbett)
	- Apply presentation forms features and discretionary features in one go in
	  Indic shaper, which seems to match Uniscribe and CoreText behaviour.
	  (Behdad Esfahbod, David Corbett)
	- Various bug fixes.
	- New API
	   +hb_set_add_sorted_array() (Andrew John)
   Overview of changes leading to 4.0.1
     Friday, March 11, 2022
	- Update OpenType to AAT mappings for “hist” and “vrtr” features.
	  (Florian Pircher)
	- Update IANA Language Subtag Registry to 2022-03-02. (David Corbett)
	- Update USE shaper to allow any non-numeric tail in a symbol cluster, and
	  remove obsolete data overrides. (David Corbett)
	- Fix handling of baseline variations to return correctly scaled values.
	  (Matthias Clasen)
	- A new experimental hb_subset_repack_or_fail() to repack an array of objects,
	  eliminating offset overflows. The API is not available unless HarfBuzz is
	  built with experimental APIs enabled. (Qunxin Liu)
	- New experimental API
	   +hb_link_t
	   +hb_object_t
	   +hb_subset_repack_or_fail()
   Overview of changes leading to 4.0.0
     Tuesday, March 1, 2022
	- New public API to create subset plan and gather information on things like
	  glyph mappings in the final subset. The plan can then be passed on to perform
	  the subsetting operation. (Garret Rieger)
	- Draw API for extracting glyph shapes have been extended and finalized and is
	  no longer an experimental API. The draw API supports glyf, CFF and CFF2
	  glyph outlines tables, and applies variation settings set on the font as well
	  as synthetic slant. The new public API is not backward compatible with the
	  previous, non-public, experimental API. (Behdad Esfahbod)
	- The hb-view tool will use HarfBuzz draw API to render the glyphs instead of
	  cairo-ft when compiled with Cairo 1.17.5 or newer, setting HB_DRAW
	  environment variable to 1 or 0 will force using or not use the draw API,
	  respectively. (Behdad Esfahbod)
	- The hb-shape and hb-view tools now default to using HarfBuzz’s own font
	  loading functions (ot) instead of FreeType ones (ft). They also have a new
	  option, --font-slant, to apply synthetic slant to the font. (Behdad Esfahbod)
	- HarfBuzz now supports more than 65535 (the OpenType limit) glyph shapes and
	  metrics. See https://github.com/be-fonts/boring-expansion-spec/issues/6 and
	  https://github.com/be-fonts/boring-expansion-spec/issues/7 for details.
	  (Behdad Esfahbod)
	- New API to get the dominant horizontal baseline tag for a given script.
	  (Behdad Esfahbod)
	- New API to get the baseline positions from the font, and synthesize missing
	  ones. As well as new API to get font metrics and synthesize missing ones.
	  (Matthias Clasen)
	- Improvements to finding dependencies on Windows when building with Visual
	  Studio. (Chun-wei Fan)
	- New buffer flag, HB_BUFFER_FLAG_PRODUCE_UNSAFE_TO_CONCAT, that must be set
	  during shaping for HB_GLYPH_FLAG_UNSAFE_TO_CONCAT flag to be reliably
	  produced. This is to limit the performance hit of producing this flag to when
	  it is actually needed. (Behdad Esfahbod)
	- Documentation improvements. (Matthias Clasen)

9a7e4d8506 Switch checksums from MD5 to BLAKE2 
Historically, the MD5 checksums in our LFS files serve as a protection
against broken downloads, or accidentally corrupted source files.

While the sources are nowadays downloaded via HTTPS, it make sense to
beef up integrity protection for them, since transparently intercepting
TLS is believed to be feasible for more powerful actors, and the state
of the public PKI ecosystem is clearly not helping.

Therefore, this patch switches from MD5 to BLAKE2, updating all LFS
files as well as make.sh to deal with this checksum algorithm. BLAKE2 is
notably faster (and more secure) than SHA2, so the performance penalty
introduced by this patch is negligible, if noticeable at all.

In preparation of this patch, the toolchain files currently used have
been supplied with BLAKE2 checksums as well on
https://source.ipfire.org/.
