* meson.build: Check the return value of `run_command`.
By default, errors are not checked and a command that is somehow broken will
just capture incorrect output (likely an empty string). Current development
versions of meson now raise a warning for this implicit behavior, and advise
explicitly setting the `check:` keyword argumend to determine whether a
failing return code should be considered an error.
Since none of the commands in this project are expected to fail, mark them
as required to succeed.

[truetype] Binary search through the `hdmx` records.
The `hdmx` table is supposed to be sorted by ppem size, which
enables binary search. We also drop the check for the sufficient
length of the record because it is now enforced when the table
is loaded.
* include/freetype/internal/tttypes.h (TT_FaceRec): Store the `hdmx`
record pointers sorted by ppem instead of ppem's themselves.

[truetype] Honor FT_LOAD_ADVANCE_ONLY if `hdmx` is usable.
This simply shortcuts the glyph loading if FT_LOAD_ADVANCE_ONLY

Particularly, the classic v35 interpreter or "verified" ClearType
fonts might see 100x speed up in retrieving the hdmx cache.

[bdf] Fix use of uninitialized value.
In _bdf_readstream if the data contained no newline then the buffer
would continue to grow and uninitialized data read until either the
uninitialized data contained a newline or the buffer reached its
maxiumum size. The assumption was that the line was always too long and
the buffer had been filled, however this case can also happen when there
is not enough data to fill the buffer.
Correct this by properly setting the cursor to the end of the available
data, which may be different from the end of the buffer. This may still
result in one extra allocation, but only on malformed fonts.
* src/bdf/bdflib.c (_bfd_readstream): Correctly update cursor. Remove
unread set of `avail`.

Provide C++ versions for public macros with casts.
Many FreeType clients use C++. However `g++ -Wold-style-cast` warns for
macros with C-style casts even for system header files; this also affects
directories included with `-isystem`. While this could be seen as a problem
with g++, the problem is more a philosophical one: Over the time, C and C++
diverged more and more, and some features of C are no longer the 'right'
solution in C++.
* include/freetype/config/public-macros.h (FT_STATIC_CAST,
FT_REINTERPRET_CAST): New macros.
* include/freetype/freetype.h (FT_ENC_TAG, FT_LOAD_TARGET_,

[mm] Tolerate missing Blend dictionary entries
In a Multiple Master font, the Blend dictionary must contain valid
Private, FontInfo, and FontBBox. The current code will error if any of
these are present and invalid, but will not error and will provide
uninitialized data if the Blend dictionary exists but does not contain
one of these entries. This change reverts to the older behavior of
treating any missing entries as containing all zero data and not
returning an error.
In the future it may be best to keep track of when these are actually
initialized and error if they are not.
* src/type1/t1load.c (t1_allocate_blend): Zero initiailize.

[mm] Delay setting blend weight and design position.
Previously the `blend->weight_vector`, `blend->default_weight_vector`,
and `blend->design_pos` were set early to allocated but uninitialized
memory under the assumption that the memory would eventually be
initialized. However, it is possible that some of the required
keywords may not actually be present, leaving the memory uninitialized.
This is different from a present but invalid table, which would produce
an error.
Reported as
https://bugs.chromium.org/p/chromium/issues/detail?id=1261762
* src/type1/t1load.c (t1_allocate_blend): Remove early allocation and
initialization.
(parse_blend_design_positions, parse_weight_vector): Parse into local
and assign to blend if valid.
(T1_Open_Face): Check that if a blend exists that it has the weight
vector and design positions.

The vstore->regionCount and vstore->dataCount were read directly

to clean up.

[sfnt] Delay setting gasp ranges and count until computed.
Previously, the gasp.numRanges was set and gasp.gaspRanges was
allocated and assigned before a possible early exit if the frame could
not be entered. It is also possible that the gaspRanges allocation
could fail but the numRanges still be set to non-zero. In such cases
an error would be returned, but the face would have a gasp in an
inconsistent state which may still be accessed.

* src/sfnt/ttload.c (tt_face_load_gasp): Delay setting gasp.numRanges

[sfnt] Delay setting names and langTags until computed.
Previously, the table->names and table->langTags fields were created
pointing to uninitialized memory and an early exit could happen if the
frame could not be entered. The caller would then be unable to properly
dispose of the memory as the string fields had not been initialized.
Reported as
https://bugs.chromium.org/p/chromium/issues/detail?id=1261343
* src/sfnt/ttload.c (tt_face_load_name): delay setting table->langTags
and table->names until after the memory they will point to is fully

autogen.sh: Only copy submodules if building from a git branch.
`autogen.sh` fails if building from a standard source tarball. Firstly, git
expects to be called in a git repository, then `copy_submodule_files`
blindly attempts to copy files.
Debian, Ubuntu, Linux Mint, and other derivatives all run `autogen.sh`
before compiling to regenerate build files.
This patch ensures that various git commands are only called and 'dlg' files
are only copied if `autogen.sh` is called from a git repository.
