[smooth] Reduce shift in multiply-shift optimization.
* src/smooth/ftgrays.c (FT_UDIVPREP, FT_UDIV): Reduce shift.
Smaller shifts that keep the division operands of FT_UDIVPREP within
32 bits result in slightly faster divisions, which is noticeable in
the overall performance. The loss of precision is tolerable until the
divisors (the components dx and dy) approach 32 - PIXEL_BITS. With
PIXEL_BITS = 8, this corresponds to 65,000 pixels or the bitmap size
that we refuse to render anyway.

* meson.build: Fix zlib support.
This commit synchronizes zlib support with both autotools and cmake: If no
external zlib is found (or intentionally disabled on the command line), use
the internal zlib by undefining `FT_CONFIG_OPTION_SYSTEM_ZLIB` without
modifying `FT_CONFIG_OPTION_USE_ZLIB`.
Also improve summary output.

Fix invalid memory access in `bsdf` rasterizer.
Do not generate SDF from bitmap if the `FT_GLYPH_OWN_BITMAP` flag is not
set. In some cases the bitmap buffer is freed but still points to a valid
address; to handle those cases check the flag before accessing the memory.
* src/sdf/ftsdfrend.c (ft_bsdf_render): Handle the above case.
Also, return an error message if the bitmap's rows/pitch is invalid,
otherwise `slot->buffer` might be assigned to some invalid memory location.
(ft_sdf_render): Same as above.
Plus, move the outline back to original state after rasterization and not if
any error occurs.

[autofit] Split `afwrtsys.h`.
The header file `afwrtsys.h` has two distinct functions: to include the
required writing system headers and also to generate code for each writing
system. At each current use site only one or the other is used, with
various macro trickery selecting one or the other. Split this header into
`afws-decl.h` for the required writing system declarations and `afws-iter.h`
for iterating over the writing systems to generate code.
The motivation for this change is that the Visual C++ compiler treats the
standard include guard idiom like `#pragma once` 'if no non-comment code or
preprocessor directive comes before or after the standard form of the
idiom'. It appears to check this after macro expansion, so if
`WRITING_SYSTEM` expands to empty the bottom of `afwrtsys.h` is empty and
looks like the standard include guard idiom which is treated like `#pragma
once`, so subsequent inclusion of `afwrtsys.h` is elided.
Fixes #1075.

Document direct header inclusion valid since 2.6.1.
Since commit e13391333 'Make macros for header file names optional.' the
header file layout has become public and using the macro expansions for
includes is no longer required. While this happened in 2.10.3, the header
file layout had not changed since commit 392cf22f8a5 'Another adjustment to
header locations.' in 2.6.1. Retroactively make the header file layout
public back to 2.6.1 to speed adoption.

* src/smooth/ftgrays.c: Fix compilation if `FT_LONG64` is undefined.
The code assumed that if `__SSE2__` is defined, then 64-bit integer
types are available. This is not the case apparently for certain
multilib compiler targets like 'x86_32.x86' used by Gentoo.
This patch fixes the issue by disabling the special code path when
64-bit integer types are not available.
Fixes #1071.

Guard inclusion of emmintrin.h
Guard inclusion of emmintrin.h with "#ifdef __SSE2__". The gcc version
of this header, xmmintrin.h, and mmintrin.h check that the appropriate
defines are set before defining anything (are internally guarded).
However the clang versions of these includes are not internally guarded.
As a result of this, externally guard the inclusion of these headers.

[smooth] Implement Bezier quadratic arc flattenning with DDA
Benchmarking shows that this provides a very slighty performance
boost when rendering fonts with lots of quadratic bezier arcs,
compared to the recursive arc splitting, but only when SSE2 is
available, or on 64-bit CPUs.
On a 2017 Core i5-7300U CPU on Linux/x86_64:
./ftbench -p -s10 -t5 -cb .../DroidSansFallbackFull.ttf
Before: 4.033 us/op (best of 5 runs for all numbers)
After: 3.876 us/op
./ftbench -p -s60 -t5 -cb .../DroidSansFallbackFull.ttf
Before: 13.467 us/op

[smooth] Minor speedup to smooth rasterizer
This speeds up the smooth rasterizer by avoiding a
conditional branches in the hot path. Namely:
- Define a fixed "null cell" which will be pointed
to whenever the current cell is outside of the current
target region. This avoids a "ras.cell != NULL"
check in the FT_INTEGRATE() macro.
- Also use the null cell as a sentinel at the end of
all ycells[] linked-lists, by setting its x coordinate
to INT_MAX. This avoids a 'if (!cell)' check in
gray_set_cell() as well.
- Slightly change the worker struct fields to perform
a little less operations during rendering.
Example results (on a 2013 Corei5-3337U CPU)
out/ftbench -p -s10 -t5 -bc /usr/share/fonts/truetype/droid/DroidSansFallbackFull.ttf
Before: 5.472 us/op
After: 5.275 us/op
out/ftbench -p -s60 -t5 -bc /usr/share/fonts/truetype/droid/DroidSansFallbackFull.ttf

tests/scripts/download-test-fonts.sh rewrite in Python3
Replaces download-test-fonts.sh with download-test-fonts.py
which does the same work, and also avoids downloading anything
if the files are already installed with the right content.
Now uses the first 8 byte of each file's sha256 hash for the
digest.

Support architectures where `long` is smaller than pointers.
I am currently trying to compile FreeType for CHERI-extended ISAs
(CHERI-RISC-V and Arm's Morello), but I am getting compiler warnings
from the `FT_UINT_TO_POINTER` macro. When compiling with the CHERI
Clang compiler, not using `uinptr_t` for casts between integers an
pointers results in the following `-Werror` build failures:
```
In file included from .../src/truetype/truetype.c:22:
.../src/truetype/ttgload.c:1925:22: error:
cast from provenance-free integer type to pointer type will
give pointer that can not be dereferenced
[-Werror,-Wcheri-capability-misuse]
node->data = FT_UINT_TO_POINTER( glyph_index );
^
.../include/freetype/internal/compiler-macros.h:79:34: note:
expanded from macro 'FT_UINT_TO_POINTER'
```
* include/freetype/internal/compiler-macros.h (FT_UINT_TO_POINTER):
The ISO C standard compliant fix for this would be to use
`uintptr_t` from `stdint.h`, but I am not sure if this is supported
by the minimum compiler version. Therefore, use the
compiler-defined `__UINTPTR_TYPE__` macro (supported in GCC 4.6+ and
Clang since about 3.0) before checking for `_WIN64` and falling back
to `unsigned long`.

[base] Fix `FT_Open_Face`'s handling of user-supplied streams.
This was already true (though undocumented) most of the time, but
not if `FT_NEW` inside `FT_Stream_New` failed or if the
`FT_OPEN_XXX` flags were bad.
Normally, `FT_Open_Face` calls `FT_Stream_New`, which returns the
user-supplied stream unchanged, and in case of any subsequent error
in `FT_Open_Face`, the stream is closed via `FT_Stream_Free`.
Up to now, however, `FT_Stream_New` allocates a new stream even if
it is already given one by the user. If this allocation fails, the
user-supplied stream is not returned to `FT_Open_Face` and never
closed. Moreover, the user cannot detect this situation: all they
see is that `FT_Open_Face` returns `FT_Err_Out_Of_Memory`, but that
can also happen after a different allocation fails within the main
body of `FT_Open_Face`, when the user's stream has already been
closed by `FT_Open_Face`. It is plausible that the user stream's
`close` method frees memory allocated for the stream object itself,
so the user cannot defensively free it upon `FT_Open_Face` failure
lest it ends up doubly freed. All in all, this ends up leaking the
memory/resources used by user's stream.
Furthermore, `FT_Stream_New` simply returns an error if the
`FT_OPEN_XXX` flags are unsupported, which can mean either an
invalid combination of flags or a perfectly innocent
`FT_OPEN_STREAM` on a FreeType build that lacks stream support.
With this patch, the user-supplied stream is closed even in these
cases, so the user can be sure that if `FT_Open_Face` failed, the
stream is definitely closed.
* src/base/ftobjs.c (FT_Stream_New): Don't allocate a buffer
unnecessarily.
Move error-handling code to make the control flow more obvious.
Close user-supplied stream if the flags are unsupported.
`FT_Stream_Open` always sets `pathname.pointer`, so remove the
redundant (re)assignment. None of the `FT_Stream_Open...` functions
uses `stream->memory`, so keep just one assignment at the end,
shared among all possible control flow paths.
('Unsupported flags' that may need a stream closure can be either an
invalid combination of multiple `FT_OPEN_XXX` mode flags or a clean
`FT_OPEN_STREAM` flag on a FreeType build that lacks stream
support.)
