[pfr] Fortify the kerning code.
Any array index must be strictly less then the array size. Therefore,
we must reject indexes that are equal to the array size. Alternatively,

In addition, it is ok to decrement zero (.notdef) and get UINT_MAX,
which is then automatically rejected in the bounds check.

[base] Build outlines in amortized constant time.
When resizing the loader's points and contours, resize them to at least 1.5
times their current size. The code currently only reserves as much space as
is currently required, leading to O(n^2) runtime when adding points one at a
time.
This change does not attempt to ever shrink the loader's point and contour
storage since this was not attempted previously either. The 1.5 multiple
was chosen as a trade-off between potentially unused space and the runtime.

doc: Clarify description of `FT_Stream_IoFunc`.
The existing documentation comments on `FT_Stream_IoFunc` hinted at the dual
seek/read behavior required for custom stream implementations to work, but
it didn't explicitly explain it. Without looking at the internals of
FreeType, it was easy for someone to assume their implementation should
handle both seek and read operations all the time. If this is done, you get
a variety of errors, but mostly just `Unknown_File_Format` (error code
0x02).

FreeType can be located by consuming projects that use
`find_package(Freetype)` either via the old `MODULE` path (which uses
`FindFreetype.cmake` supplied by CMake), or via the new `CONFIG` path (which
uses `freetype-config.cmake` as supplied by this project). Up to this point
the CMake module has supplied the target `Freetype::Freetype` and the config
file provided by this project the target `freetype`. Now we supply both
`freetype` and `Freetype::Freetype` so that consuming projects can always
use the target `Freetype::Freetype` regardless of what path was taken by
`find_package(Freetype)`.
Fixes #1165.

This avoids cyclic subproject configuration when the 'harfbuzz' feature is

[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
indicating invalid data since there is no means to provide a dictionary.

[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.
