[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.
This is alternative to !132 and discussed in
https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=43708
* src/base/ftobjs.c (FT_Load_Glyph): Deal with zero scale.

[pshinter] Avoid accessing uninitialized zone.
The `normal_top.count` may be 0, implying no `normal_top.zones` exist.
The code must not access these (non-existent) `normal_top.zones`.
* src/pshinter/pshalgo.c (ps_hints_apply): Do not assume that
`normal_top.zones[0]` is initialized. Test `normal_top.count`
before using `normal_top.zones[0]`. Do not rescale if there are no
`zones`.

According to the bzip documentation it is undefined what will happen if
`BZ2_bzDecompress` is called on a `bz_stream` it has previously returned an
error against. If `BZ2_bzDecompress` returns anything other than `BZ_OK`
the only valid next action is `BZ2_bzDecompressEnd`.

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.
