Document `FT_Outline_Decompose` degenerate segments.
`FT_Outline_Decompose` does not filter out and can return degenerate
segments in an outline. This can be surprising when attemping to
stroke such an outline. Clarify the existing documentation on this
matter to cover all forms of degeneracy (without specifying exactly
how they will be reported), why they might arise, and better explain in
what cases they may be an issue.

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] Some organizational changes.
We now first apply zlib's `zlib2ansi` script, then FreeType's patch file.
* src/gzip/README.freetype: Updated.
* patches/0001-zlib-Fix-zlib-sources-to-compile-for-FreeType.patch: Renamed
to...
* 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.

[meson] Change Zlib configuration option.
* meson_options.txt, meson.build: Change the format of the 'zlib' meson
build configuration option to be a combo with the following choices:
- none: Do not support gzip-compressed streams at all.
- internal: Support gzip-compressed streams using the copy of the gzip
sources under `src/gzip/`; this should only be used during development
to ensure these work properly.
- external: Support gzip-compressed streams using the 'zlib' Meson
subproject, linked as a static library.
- system: Support gzip-compressed streams using a system-installed version
of zlib.
- auto: Support gzip-compressed streams using a system-installed version
of zlib, if available, or using the 'zlib' subproject otherwise. This
is the default.
- disabled: Backward-compatible alias for 'none'.
- enabled: Backward-compatible alias for 'auto'.

[sfnt] Fix off-by-one error.
The 0-base index is equal to the number of previosly parsed entries.
It is an error to adjust it by one to get the number truncated by
a stream error. This is probably inconsequential because valid
entries are correctly accounted for.
* src/sfnt/ttload.c (check_table_dir): Do not adjust the truncated
number of tables.

[truetype] Reset localpoints when varying cvt.
When iterating over the cvt tuples and reading in the points it is necessary
to set all of `localpoints`, `points`, and `point_count` in all cases. The
existing code did not reset `localpoints` to `NULL` when there were no
private point numbers. If the previous tuple did have private point numbers
and set `localpoints` to `ALL_POINTS` this would not be cleared and the
wrong branch would be taken later, leading to possible heap buffer overflow.
* src/truetype/ttgxvar.c (tt_face_vary_cvt): Reset `localpoints` to `NULL`
when it isn't valid.

* meson.build: Optimize lookup for `python3` program.
The python module's `find_installation` method is intended to provide
routines for compiling and installing python modules into the
`site-packages` directory. It does a couple of slow things, including run
an introspection command to scrape sysconfig info from the detected
interpreter, which are not needed for the sole use case of invoking the
found installation as an executable.
Furthermore, when invoked without the name or path of a python binary, it is
hardcoded to always look for `python3` corresponding to the interpreter
meson itself uses to run. So using `find_installation` did not even allow
detecting `python2` as a fallback.
Instead, switch to a simple `find_program` lookup that finishes as soon as
the program is found.

* builds/meson/*.py: Fix name of python executable for auxiliary scripts.
The previous change to check the return code of `run_command` invocations
caused the CI to fail. Although most scripts used `python_exe` as the
program command, the script to determine the project version did not.
But, all scripts used `python` as the shebang, and this is not available on
all systems. Particularly Debian does not provide a `python` command,
though `python3` does exist. This meant that formerly the version number
was lacking, and now the build simply fails.
Instead, rely on `python3` since it is guaranteed to exist when running
meson, and `python2` is end of life anyway.

* meson.build: Check the return value of `run_command`.
By default, errors are not checked and a command that is somehow broken will
just capture incorrect output (likely an empty string). Current development
versions of meson now raise a warning for this implicit behavior, and advise
explicitly setting the `check:` keyword argumend to determine whether a
failing return code should be considered an error.
Since none of the commands in this project are expected to fail, mark them
as required to succeed.

[truetype] Binary search through the `hdmx` records.
The `hdmx` table is supposed to be sorted by ppem size, which
enables binary search. We also drop the check for the sufficient
length of the record because it is now enforced when the table
is loaded.
* include/freetype/internal/tttypes.h (TT_FaceRec): Store the `hdmx`
record pointers sorted by ppem instead of ppem's themselves.
* src/truetype/ttpload.c (tt_face_load_hdmx): Prudently sort records.

advances.

fonts might see 100x speed up in retrieving the hdmx cache.

[bdf] Fix use of uninitialized value.
In _bdf_readstream if the data contained no newline then the buffer
would continue to grow and uninitialized data read until either the
uninitialized data contained a newline or the buffer reached its
maxiumum size. The assumption was that the line was always too long and
the buffer had been filled, however this case can also happen when there
is not enough data to fill the buffer.
Correct this by properly setting the cursor to the end of the available
data, which may be different from the end of the buffer. This may still
result in one extra allocation, but only on malformed fonts.
* src/bdf/bdflib.c (_bfd_readstream): Correctly update cursor. Remove
unread set of `avail`.
