[sfnt] Fix bounds check in SVG.
The `SVG_DOCUMENT_LIST_MINIMUM_SIZE` macro is non trivial and not
protected by parentheses. As a result, the expression
`table_size - SVG_DOCUMENT_LIST_MINIMUM_SIZE` expands to
`table_size - 2U + SVG_DOCUMENT_RECORD_SIZE` instead of the expected
`table_size - (2U + SVG_DOCUMENT_RECORD_SIZE)`. This causes an incorrect
bounds check which may lead to reading past the end of the `SVG ` table.
* src/sfnt/ttsvg.c (tt_face_load_svg): wrap macro definitions in
parentheses.

[psaux] Full bounds check for OtherSubr 19.
It is possible for OtherSubr 19 to be invoked when `decoder->buildchar` is
NULL (so that `decoder->len_buildchar` is 0), the `blend` is non-NULL with
`blend->num_designs` set to 2, and the user supplied `idx` to be large (for
example 0xFFFFFFFE). Since these are all `FT_UInt32` the existing bounds
check overflows in a well defined manner, allowing for an invalid call to
`memcpy`.
In addition, it is possible to call OtherSubr 19 with
`decoder->len_buildchar`, `blend->num_designs`, and `idx` all zero (implying
that `blend->weight_vector` and `decoder->buildchar` are NULL). This passes
the bounds check (it is logically always fine to copy nothing starting at
index zero) but may invoke undefined behavior in `ft_memcpy` if it is backed
by `memcpy`. Calling `memcpy` with either the `src` or `dst` NULL is
undefined behavior (even if `count` is zero).
* src/psaux/psintrp.c (cf2_interpT2CharString): Correctly check that
`blend->num_designs` can be copied to `decoder->buildchar[idx]`.
Also avoid passing NULL to `ft_memcpy`.

[base] Undefined scale means no scale.
It might be surprising that FreeType does not have default ppem and
the size has to be set explicitly or face undefined behavior with
undefined variables and errors. This offers an alternative to
missing or zero scale by simply setting FT_LOAD_NO_SCALE. Defined
behavior is bettr than undefined one.

Revert "[bzip2] Avoid use of uninitialized memory."
This reverts commit d276bcb7f0c02c20d3585b2e5626702df6d140a6.
The original commit did avoid the use of uninitialized memory. However,
it appears that the original commit is no longer required. The
underlying issue was resolved by a change in freetype2-testing "Build
bzip2 correctly." [0]. Prior to [0] bzip2 was built without msan, so
bzip2 writes were not tracked or considered initialized. Clearing
`buffer` in the original commit allowed msan to see the `buffer` content
initialized once in FreeType code, but msan saw no writes into buffer
from bzip2. With bzip2 now built with msan, the bzip2 writes are
properly instrumented and msan sees the bzip2 writes into the buffer. As
a result the original commit can be safely reverted to allow for better
detection of other uninitialized data scenarios.
* src/bzip2/ftbzip2.c (FT_Stream_OpenBzip2): Revert to using `FT_QNEW`.

[type42] Track how much type42 ttf data is available.
Currently `T42_Open_Face` eagerly allocates 12 bytes for the ttf header
data which it expects `t42_parse_sfnts` to fill out from /sfnts data.
However, there is no guarantee that `t42_parse_sfnts` will actually be
called while parsing the type42 data as the /sfnts array may be missing
or very short. This is also confusing behavior as it means
`T42_Open_Face` is tightly coupled to the implementation of the very
distant `t42_parse_sfnts` code which requires at least 12 bytes to
already be reserved in `face->ttf_data`.
`t42_parse_sfnts` itself eagerly updates `face->ttf_size` to track how
much space is reserved for ttf data instead of traking how much data has
actually been written into `face->ttf_data`. It will also act strangely
in the presense of multiple /sfnts arrays.
* src/type42/t42objs.c (T42_Open_Face): ensure `ttf_data` is initialized
to NULL. Free `ttf_data` on error.
* src/type42/t42parse.c (t42_parse_sfnts): delay setting `ttf_size` and
set it to the actual number of bytes read. Ensure `ttf_data` is freed
if there are multiple /sfnts arrays or there are any errors.

[zlib] Don't typedef `ptrdiff_t`.

* src/gzip/README.freetype: Updated.
* patches/0001-zlib-Fix-zlib-sources-to-compile-for-FreeType.patch: Renamed

* patches/freetype-zlib.diff: This.
Clean up description, then regenerate it as follows:
- Copy unmodified files from `zlib` repository.
- Run `zlib2ansi` script.
- Run `git diff -R > patches/freetype-zlib.diff.new`.
- Insert patch description of old diff file, then replace old diff with
new diff file.

[gzip] Update sources to zlib 1.2.11
This can be tested by building with the Unix development build
make setup devel
make
or by building the freetype-demos programs with
meson setup build -Dfreetype2:zlib=internal
meson compile -C out
and trying to run `ftview` with a `.pcf.gz` font file.
* src/gzip/ftgzip.c, src/gzip/rules.mk: Update for new zlib sources. Also
remove the temporary fix introduced in commit 6a431038 to work around the
fact that the internal sources were too old.
* src/gzip/README.freetype: New file describing the origin of the sources
and how they were modified.
* src/gzip/patches/*: Patch files applied to original sources.
* src/gzip/*: Updated zlib sources with the patch file(s) from
`src/gzip/patches/` applied, followed by a conversion with zlib's
`zlib2ansi` script.
