d5d048bbfe 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).

f7daf9d293 [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.
