[base] 'close' callback may not use `stream->memory`.
The documentation for `FT_StreamRec::memory` states that it 'shouldn't be
touched by stream implementations'. This is true even for internal
implementations of the 'close' callback, since it is not guaranteed that
`memory` will even be set when the 'close' callback occurs.
* src/base/ftobjs.c (new_memory_stream): stash current `memory` in
`stream->descriptor`.
(memory_stream_close): Use it.

[base] Always close user-provided stream.
The `FT_Open_Face` documentation states
> If `FT_OPEN_STREAM` is set in `args->flags`, the stream in `args->stream`
> is automatically closed before this function returns any error (including
> `FT_Err_Invalid_Argument`).
However, if the user provides a stream in `args.stream` with
`FT_OPEN_STREAM` set and a `close` function, but then for some reason passes
NULL for `aface` and a non-negative `face_index`, the error
`Invalid_Argument` is returned but the `close` callback will not be called
on the user-provided stream. This may cause resource leaks if the caller is
depending on the `close` callback to free resources.
The difficulty is that a user may fill out a `FT_StreamRec` and pass its
address as `args.stream`, but the stream isn't really 'live' until
`FT_Stream_New` is called on it (and `memory` is set). In particular, it
cannot really be cleaned up properly in `ft_open_face_internal` until the
stream pointer has been copied into the `stream` local variable.
* src/base/ftobj.c (ft_open_face_internal): Ensure that user-provided
`args.stream.close` is called even with early errors.

[base] Fix leak of internal stream marked external.
`open_face_from_buffer` allocates a new `FT_Stream` to pass to
`ft_open_face_internal`. Because this is an `FT_OPEN_STREAM`,
`ft_open_face_internal` will mark this as an 'external stream', which the
caller must free. However, `open_face_from_buffer` cannot directly free it
because the stream must last as long as the face. There is currently an
attempt at this by clearing the 'external stream' bit after
`open_face_from_buffer` returns successfully. However, this is too late as
the original stream may have already been closed and the stream on the face
may not be the same stream as originally passed.
It is tempting to use `FT_OPEN_MEMORY` and let `ft_open_face_internal`
create the stream internally. However, with this method there is no means
to pass through a 'close' function to the created stream to free the
underlying data, which must be owned by the stream.
A possibility is to check on success if the stream of the face is the same
as the original stream. If it is then unset the external flag. If not,
then free the original stream. Unfortunately, while no current
implementation does so, it is possible that the face still has the original
stream somewhere other than as the `FT_FaceRec::stream`. The stream needs
to remain available for the life of the face or until it is closed,
whichever comes earlier.
The approach taken here is to let the stream own itself. When the stream is
closed it will free itself.
* src/base/ftobjs.c (memory_stream_close): Free `stream`.
(open_face_from_buffer): Simplify error handling, since
`ft_open_face_internal` always closes `args.stream` on any error.

[truetype] Reset cvt and storage in context load.
Currently the cvt and storage are saved and restored in `TT_RunIns`.
However, this is too granular as the cvt and storage area should be set to
the original cvt and storage area only when setting up the hinting context.
This allows for the cvt and storage area to be modified while parsing
multiple glyphs, as is the case with composite glyphs.
* src/truetype/ttinterp.h (TT_ExecContextRec): Remove `origCvt` and
`origStorage`.
* src/truetype/ttinterp.c (TT_RunIns): Don't save and restore the cvt and
storage area.
(Modify_CVT_Check, Ins_WS): Switch from "if in glyph and using original data
do copy on write" to "if in glyph and not using glyph specific data do copy
on write".

[truetype] Keep variation store consistent.
`tt_var_load_item_variation_store` fills out a `GX_ItemVarStore`. While it
may return an error, the item store must be left in a consistent state so
that any use or destruction of the item store can properly use or free the
data in it. Before this change the counts from the font data were read
directly into the item store before the actual allocation of the arrays to
which they referred. There exist many opportunities between the time the
counts are read and the arrays are allocated to return early due to invalid
data. When this happened the item store claimed to have entires it actually
did not, leading to crashes later when it was used.
Fixes: https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=54449
* src/truetype/ttgxvar.c (tt_var_load_item_variation_store): Read the counts
into local variables and store them in the item store only after the related
arrays are actually created on the item store.

[base] Report used stream's external status.
In `open_face` the initial stream is set on the face, along with the
information about if FreeType is the owner of the stream object itself. The
loaders may in the course of their work replace this stream with a new
stream (as is the case for 'woff' and 'woff2'), which may have a different
ownership than the initial stream object (likely the original stream object
is owned by the user and is external, while the new stream object is created
internally to FreeType and is internal). When the stream is replaced, the
face's flags are updated with the new ownership status.
However, `open_face` cannot itself free this stream as its caller
`ft_open_face_internal` is responsible for this. In addition, in the case
of an error `open_face` cannot return an actual face with the new stream and
its ownership status to the caller. As a result, it must pass this
information back to the caller as a sort of "failed face" so that the caller
can clean up.
`open_face` was already passing back the new stream but was not passing back
the stream ownership information. As a result the stream may not have been
free'd when needed.
Fixes https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=54700
* src/base/ftobjs.c (open_face): Pass back the ownership information as
well.
(ft_open_face_internal): Updated.

(TT_CONFIG_OPTION_NO_BORING_EXPANSION): New macro.
* src/truetype/ttgxvar.c (ft_var_load_avar): Use it to disable 'avar'

example, the 'avar' table 2.0 codepath was not performing a bounds check at
all.

code.

[truetype] Restore behavior of ft_var_load_hvvar
* src/truetype/ttgcvar.c (ft_var_load_hvvar): restore previous behavior
In a previous change [0] the behavior of `ft_var_load_hvvar` was changed
to not load the item variation store if it was at offset 0, but not
return an error when this happened. This broke any users, like
`tt_hvadvance_adjust`, that rely on successful completion of
`ft_var_load_hvvar` to imply that returned table's `itemStore` had been
initialized. This lead such users to dereference NULL.
This change appears to have been unintentional and unrelated to the
actual avar2 changes. As a result, fix these NULL dereferences by
restoring the code to always attempt to initialize the `itemStore`.

[bdf, pfr, psnames] Accelarate charmap searches.
The binary searches within charmaps can be accelerated because they
often contain dense continuous blocks of character codes. Within such
blocks, you can predict matches based on misses. This method has been
deployed in `bdf` since 0f122fef34; we only refactor it there. We now
use it in `pfr` and `psnames`, which speeds up the unicode charmap
access by about 50% in PFR and Type 1 fonts.
* src/bdf/bdfdrivr.c (bdf_cmap_char_{index,next}): Refactor.
* src/pfr/pfrcmap.c (pfr_cmap_char_{index,next}): Predict `mid` based
on the mismatch distance.
* src/psnames/psmodule.c (ps_unicodes_char_{index,next}): Ditto.

[truetype] Add support for `avar` table 2.0 format.
See
https://github.com/harfbuzz/boring-expansion-spec/blob/main/avar2.md
for the specification.
Currently, this is implemented only in most recent OS versions on Apple
platforms and in the HarfBuzz library, but it is expected to be added to the
OpenType standard soon.
* src/truetype/ttgxvar.h (GX_AVarTableRec): New structure.
(GX_BlendRec): Use it to replace `avar_segment` with `avar_table`.
* src/truetype/ttgxvar.c (ft_var_load_avar): Load new table version.
(ft_var_to_normalized, tt_done_blend): Extend for new format.
(ft_var_load_hvvar, ft_var_to_design): Updated.

(read_paint): Use it – after the start pointer `p` has been checked for
whether it allows reading the format byte, each successive paint table field
read need to be bounds-checked before reading further values.
