Suggested by Alexei. `UL' is only needed for 16bit compilers, but
it seems noone is using this anymore (and we no longer test whether
FreeType compiles in such an environment). Otherwise, it is easy to
add the postfix to the `AF_UNICODE_RANGE' macro.

* builds/unix/unix-cc.in (LINK_LIBRARY): Use `-export-symbols'.
This was commented about 10 years ago – I think the reason then to
disable libtool's `-export-symbols' option was to give some badly
programmed applications access to internal FreeType functions.
I believe that we should no longer take care of such programs; the
number of symbols exported should be rather restricted as much as
possible.

[autofit] Add support for Georgian scripts.
Georgian is problematic, since `uppercase' forms of Mkhedruli
(called Mtavruli) are not yet defined in Unicode, which means that
proper blue zones can't be defined. However, there is already a
proposal submitted to Unicode; see
http://www.unicode.org/L2/L2016/16034-n4707-georgian.pdf
Additionally, due to historical reasons, Unicode treats Khutsuri as
the same script as Mkhedruli, and so does OpenType. However, since
the two scripts have completely different shapes it can happen that
blue zones differ considerably. The tag `geok' used here (derived
from ISO 15924) to differentiate the two scripts is not an OpenType
tag in use. If we now have a font that contains both glyphs for
Mkhedruli and Khutsuri, and it uses OpenType features for both also,
HarfBuzz unavoidably treats all glyphs as `geor'. As a consequence,
blue zones for `geok' are not used for glyphs involved in the
OpenType features.
An issue not yet resolved is which OpenType feature should be used
to access Mtavruli glyph shapes; right now, FreeType doesn't set up
support for them, but it is easy to add them later on as soon as
more information is available.
* src/autofit/afblue.dat: Add blue zone data for Georgian.
* src/autofit/afblue.c, src/autofit/afblue.h: Regenerated.
* src/autofit/afscript.h: Add Georgian standard characters.
* src/autofit/afranges.c: Add Georgian data.

[pfr] Robustify bitmap strike handling (#47514).
We did a binary search for a charcode without ensuring that the
searched data is ordered. Validating the order is now done lazily,
this is, the first access to a bitmap glyph triggers the order check
in the corresponding bitmap strike.
* src/pfr/pfrtypes.h (PFR_BitmapFlags): New values
`PFR_BITMAP_VALID_CHARCODES' and `PFR_BITMAP_CHARCODES_VALIDATED'.
* src/pfr/pfrsbit.c (pfr_lookup_bitmap_data): Make `flags' argument
a pointer. Handle new PFR_BITMAP_XXX flags.
(pfr_slot_load_bitmap): Updated.

`PFR_GLYPH_COMPOUND_EXTRA_ITEMS'.
* src/pfr/pfrgload.c (pfr_glyph_load_simple,
pfr_glyph_load_compound): Use them.

[autofit] Avoid excessive stem length rounding (#25392).
* src/autofit/aflatin.c (af_latin_compute_stem_width): Add argument
to pass difference between hinted and unhinted position of base
point; use this to adjust the stem width depending on the PPEM so
that it doesn't become too large under certain circumstances.
Update all callers using value 0 for this argument except...
(af_latin_align_linked_edge): Pass position delta of base point to
`af_latin_compute_stem_width'.

[autofit] Properly handle spikes pointing to the x-axis.
An example that gets better rendered is glyph `uusignTaml' (glyph
index 2286) in font `FreeSerif.ttf' (Version 0412.2263) at 22ppem.
* src/autofit/aflatin.c (af_latin_hints_compute_segments): Properly
handle segments where the last point of the first segment is
identical to the first point in the second one. This can happen for
malformed fonts or spikes. We either merge the new segment with the
previous one (both segments point into the same direction), or we
discard the shorter segment if they point into different directions.

complete disappearance of stems.
