[sfnt] Clean up CMAP{4,12,13} handling.
This moves the charcode overflow checks upstream and turns some
while-loops into the do-while ones to avoid the uninitialized warnings.
This should slightly reduce the number of checks and jumps.
* src/sfnt/ttcmap.c (tt_cmap{4,12,13}_next,
tt_cmap{4.12.13}_char_map_linear): Remove the charcode overflow check.
(tt_cmap{4,12,13}_char_map_binary): Ditto and use do-while.
(tt_cmap{12,13}_char_next): Add the overflow check.

[cff] Rework the stream limit checks.
The old stream limit checks, before 6986ddac1ece, were good but
pointless for the crafted t2_strings. Checking limits there is
not necessary as they are created to hold all data. By using two
conditions, we can detect the actual crossing of the stream boundary
as appropriate for the stream pointer only. The t2_strings parsing
will not be triggering these checks.
* src/cff/cffparse.c (cff_parser_within_limits): Removed.
(cff_parse_real, cff_parse_integer): Redesign the stream limit check.

builds/vms/apinames_vms.bash: Fix `unzip` artifact
The problem occured when unpacking a zip file created on OpenVMS on Linux.
While OpenVMS knows many different file formats, Unix only knows stream-LF
and binary. In principle `zip` on Linux should have translated the file to
stream-LF but failed to do so. That caused the file to incorrectly contain
only one line with control-characters.

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.

* 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.

[base] Return error if requested driver is not found.
In `open_face_from_buffer` it is possible that a driver is requested but
FreeType was built without the requested module. Return an error in this
case to indicate that the request could not be satisfied, rather than trying
all existing driver modules.
* src/base/ftobjs.c (open_face_from_buffer): Return `FT_Err_Missing_Module`
if a driver is specified but not found.

[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.
