David Turner 62fea391fa Remove obsolete HAVE_STDINT_H probing macro.
This macro was updated by the unix configure script and the
`CMakeLists.txt' one, but is never used in the source tree (nor is
<stdint.h> included anywhere).

* CMakeLists.txt, builds/unix/ftconfig.in: Don't handle
`HAVE_STDINT_H'.

David Turner 4eee13404d Remove Jamfile files from the tree.
These have not been used in a very, very long time, so better remove
them.  A corresponding patch will be submitted to the
`freetype2-demos' repository.

* src/Jamfile, src/*/Jamfile, Jamrules: Delete.

Alexei Podtelezhnikov 652f886319 [smooth] Stop using dedicated LCD modules and classes.
The LCD modules were never truly independent. They mostly served as
a way to disable patented LCD rendering, which is no longer necessary.
The `smooth' module now handles LCD modes as well.

* src/smooth/ftsmooth.c (ft_smooth_lcd_renderer_class.
ft_smooth_lcdv_renderer_class): Deleted.
(ft_render_smooth): Reworked from `ft_render_smooth_generic'.
* src/smooth/ftsmooth.h: Remove dedicated LCD classes.

Moazin Khatti 6a431038c9 [gzip] Support `gzip' encoded header conditionally.
In order to support `gzip' encoded header the call to
`inflateInit2' was modified in commit 6a92b1fadd.
However, this code breaks with the outdated internal version
of zlib.  This is a temporary fix to conditionally support
`gzip' encoded header whenever a system installation of zlib
is being used.

Problem report in

  https://lists.nongnu.org/archive/html/freetype-devel/2020-02/msg00023.html

* src/gzip/ftgzip.c (FT_Gzip_Uncompress): Change the the call to
`inflateInit2' depending on whether the system installation is
being used or the internal copy.

Ben Wagner 11975fe9f6 Fix state of `FT_Face' for buggy `gvar' tables (#57923).
By resetting the blend as implemented with this commit fonts with
invalid `gvar' tables may keep calling into `ft_var_load_gvar' from
`tt_set_mm_blend' and failing, but the font was invalid anyway and
we want to keep seeing the failure in `tt_set_mm_blend'.

* src/truetype/ttgxvar.c (ft_var_load_gvar): Calculate length of
offset array once.
Allocate arrays after `FT_FRAME_ENTER' (extra check before
allocating and avoid needing to free array later if error entering
frame).
Always call `FT_FRAME_EXIT'.
Consistently set counts immediately after array initialized.
Reset the blend (particularly `blend->glyphoffsets') on failure.

Hugh McMaster 496601e504 [docs] (2/2) Fix generation of API documentation (#56745).
Creating the API Reference in the (new) `reference' sub-directory is
