Avoid strtol on non-null-terminated data.
Technically, `strtol` can only be used with C strings terminated with
`\0`. CID data is not generally null-terminated and often does not
contain a `\0` if it is hex-encoded. AddressSanitizer with `ASAN_OPTIONS`
containing `strict_string_checks=1` verifies this by using an adversarial
`strtol` that always reads to the terminating `\0`.
To avoid undefined behavior from `strtol` in `cid_parser_new`, use the
parser to parse the tokens instead of attempting to parse them ad-hoc.
This will internally use `PS_Conv_Strtol` to parse the integer, which
respects the parser's limits and directly implements the PostScript
parsing rules for integers.
* src/cid/cidparse.c (cid_parser_new): Use the parser to parse the
tokens.

* configure: Don't hardcode `grep -E`.
TeXLive still supports Solaris 5.10, where the system's `grep` doesn't
accept the `-E` option. We thus introduce an `EGREP` variable that is set
to either `grep -E` or `-egrep`.

CFF_FontRec is created but we keep it just in case.

|
* src/base/ftsystem.c (ft_ansi_stream_io): Avoid undefined behaviour.
Also short-circuit on `offset` to avoid checking `count` a second time when
`ft_ansi_stream_io` is used for reading.
Per ISO/IEC 9899:
If an argument to a function has an invalid value (such as a value outside
the domain of the function, or a pointer outside the address space of the
program, or a null pointer, or apointer to non-modifiable storage when the
corresponding parameter is not const-qualified) or a type (after
promotion) not expected by a function with variable number of arguments,
the behavior is undefined. If a function argument is described as being
an array, the pointer actually passed to the function shall have a value
such that all address computations and accesses to objects (that would be
valid if the pointer did point to the first element of such an array) are
in fact valid.
Per IEEE Std 1003.1:
size_t fread(void *restrict ptr, size_t size, size_t nitems,
FILE *restrict stream);
The `fread` function shall read into the array pointed to by `ptr` up to
`nitems` elements whose size is specified by `size` in bytes, from the
stream pointed to by `stream`.
Since the first argument to `fread` is described as being an array, its
behavior is undefined when that argument is a null pointer.
Per the documentation on `ft_ansi_stream_io`:
If `count' is zero (this is, the function is used for seeking), a non-zero
return value indicates an error.
Thus the intent is clear, and the call to `fread` can be skipped, avoiding
undefined behaviour.

* src/base/ftoutln.c (FT_Outline_Reverse): Anchor first contour points.
A cubic contour has to always start from an on-point. Therefore, we
should not swap the first with the last point, which might be off, and
obtain an invalid contour. This does not matter for conic contours.
If anything, it also saves one swap there. Fixes #1207.

[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".

[autofit] Don't depend on 'hb-ft'.
The circular dependency is still there, but at least we no longer depend on
the HarfBuzz API that is only present if HarfBuzz has been built with
FreeType support, making the bootstrapping a bit easier.
* src/autofit/ft-hb.c, src/autofit/ft-hb.h: New files, providing
`_hb_ft_font_create`, which is more or less a verbatim copy of the
corresponding HarfBuzz code from file `hb-ft.cc`.
* src/autofit/afglobal.c (af_face_globals_new): Use it.
* src/autofit/afshaper.h: Don't include `hb-ft.h` but `ft-hb.h`.
* src/autofit/autofit.c: Include `ft-hb.c`.
* LICENSE.TXT: Updated.

[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.
