New function `FT_MulAddFix` to compute the sum of fixed-point products.
This function, based on the code of `FT_MulFix`, uses 64-bit precision
internally for intermediate computations.

[stream] Fix reading s32 when long is s64
`FT_READ_LONG`, `FT_GET_LONG`, and related macros did not return
negative values when `long` is more than 32 bits. `FT_Stream_ReadULong`
would read four bytes into the LSB of an `FT_ULong` and return that.
Since this can never set the MSb of the `FT_ULong` when `FT_ULong` is
more than 32 bits the cast to `FT_Long` never resulted in a negative
value.
Fix this by modifying `FT_Stream_Read*` to return a type of the same
size as the bytes it is reading and changing the `FT_READ_*` and
`FT_GET_*` macros to cast to the same type returned by `FT_Stream_Read*`
but with the correctly signed type (instead of casting to what is
assumed to be the type of `var` which will happen automatically anyway).
There exist a few cases like with the `OFF3` variants where there isn't
generally a type with the correct size. `FT_PEEK_OFF3` works around this
loading the bytes into the three most significant bits and then doing a
signed shift down. `FT_NEXT_OFF3` also already worked correctly by
casting this signed value to another signed type. `FT_Stream_GetUOffset`
works correctly but one must be careful not to attempt to cast the
returned value to a signed type. Fortunately there is only
`FT_GET_UOFF3` and no `FT_GET_OFF3`.
All of these cases are handled correctly when reading values through
`FT_Stream_ReadFields` since it generically computes the signed value
through an `FT_Int32`. This change is essentially doing the same for
these macros.
* include/freetype/internal/ftstream.h (FT_NEXT_*, FT_GET_*, FT_READ*):
Update macros and return types to use fixed size types for fixed size
values.
* src/base/ftstream.c (FT_StreamGet*, FT_StreamRead*): Dito.

[type1] Directly search for eexec in private dict
This code originally just searched for `eexec`. This was later modified
to check that the `eexec` found is valid (not in a string or comment).
This was done by searching for `eexec` as before and then, for each
`eexec` found, searching from the beginning using the correct parsing to
see if the `eexec` was still found. If the private dictionary is large
and contains many copies of `eexec` which are not valid, the initial
part of the private dictionary is scanned once for each, potentially
leading to n^2 parsing time.
Instead of finding an initial `eexec` and then re-parsing to discover if
it is valid, drop the initial search for `eexec` and just parse to find
a valid `eexec`. This is strictly faster since the validation must
happen anyway and avoids restarting from the beginning each time an
`eexec` is found in the data.

[gzip] Handle inflate returning Z_NEED_DICT
When `inflate` returns `Z_NEED_DICT` this is currently not reported as
an error and callers may assume that the decompression succeeded when it
did not. In particular, a compressed table in a woff file may not
actually be decompressed and written as expected, leaving the backing
memory for the expanded table uninitialized.
* src/gzlip/ftgzip.c (FT_Gzip_Uncompress): treat `Z_NEED_DICT` as

[svg] Clear correct flags for doc ownership
This issue was discovered with an SVG based font with some documents
compressed and other uncompressed. After loading the first compressed
document the ownership flag on the glyph slot was set to true but never
set to false. As a result after loading a compressed document a glyph
from an uncompressed document would load fine, but when this glyph slot
was cleared it would try to free its document resulting in a wild free.

[meson] Remove `default_library=both` from `default_options`.
It is inconsistent with what all other Meson projects do.
It also prevents static linking to FreeType when it is a subproject because
`default_options` in a subproject takes precedence on values set on the main
project. For example, building 'GStreamer' with `-Ddefault_library=static`
would still dynamically link on FreeType unless the user also sets
`-Dfreetype2:default_library=static`.

[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`.

[cmake] Drop the support of CMake 2.x.

the inflation of cmake_policy() workarounds.
For better maintainability, the support of CMake 2.x is
dropped.
