[pcf] Fix handling of undefined glyph (#56067).
This commit fixes the changes from 2018-07-21, which broke charmap
iteration. We now add the default character as a new glyph with
index 0, thus increasing the number of glyphs by one (as before).
* src/pcf/pcfread.c (pcf_get_metrics): Adjust to new artificial
glyph with index 0.
Limit number of elements to 65534.
(pcf_get_bitmaps): Ditto.
Unify two loops into one; this avoids allocation of an intermediate
array.
(pcf_get_encodings): Don't flip indices but copy glyph metrics of
default character to index 0.
Also handle invalid default character.
* docs/CHANGES: Updated.

[cff] Fix boundary checks.
642bc7590c701c8cd35a9f60fa899cfa518b17ff introduced dynamically
allocated memory when parsing CFF files with the "old" engine. Bounds
checks have never been updated, however, leading to pointless
comparisons of pointers in some cases. This commit presents a
solution for bounds checks in the CFF module with an extended logic
for the "old" engine while staying as concise as possible for the
"new" one.
* src/cff/cffparse.h: Introduce the struct `CFF_T2_StringRec' and
the additional field `t2_strings' within `CFF_ParserRec'.
* src/cff/cffparse.c (cff_parser_within_limits): Move all boundary
checks into this new function and update the rest of `cffparse.c' to
use it.

* src/psaux/psintrp.c (cf2_interpT2CharString): The call to
`cf2_arrstack_setCount' may fail because the allocator ran out of
memory. When this happens the stack is still written to before the
error condition is checked. This means that FreeType writes outside
of allocated memory. This commit moves the error check prior to the
stack assignment, hence the function now properly returns with an
error condition.

[truetype] Apply MVAR hasc, hdsc and hlgp metrics to current FT_Face metrics.
Instead of setting typo or win metrics as the new FT_Face metrics
indiscriminately, apply only typo deltas to the currently active FT_Face
metrics. This prevents line height differences when e.g. the default
outlines were used as the regular face and instances for everything else.
* src/truetype/ttgxvar.c (tt_apply_mvar): Implement.

[psaux] Fix closepath (#55414).
All of the Type 1 path building is done with code common to the
revised CFF engine, with the exception of closepath, which was still
calling ps_builder_close_contour(), thus previously cached segments
were not always written to the path, and glyph corruption, or even
invalid outlines were possible.
* src/psauc/psinterp.c (cf2_interpT2CharString) <cf2_cmdCLOSEPATH>:

Fix handing of `FT_Bool'.
Before this commit we had code like
(FT_Bool)( globals->glyph_styles[gindex] & 0x8000)
Since `FT_Bool' is defined to be an `unsigned char', the code
evaluated to something like
(unsigned char)( 0x8532 & 0x8000)
which in turn expanded to
(unsigned char)( 0x8000)
and finally yielded 0x00 – i.e., false – not as expected.
Problem reported and analyzed by Tony Smith <tony.smith@macro4.com>.
* include/freetype/fttypes.h (FT_BOOL): Add a comparison against
zero so that we always have a Boolean expression.
*/*: Replace castings to `FT_Bool' with calls to `FT_BOOL' where
possible.

Improve auto-hinter handling of bitmap fonts (#54681).
For bitmap fonts, `FT_Load_Glyph' should either return an error or
not set the format to `FT_GLYPH_FORMAT_OUTLINE'. However, in this
case `FT_Load_Glyph' calls into the auto-hinter which calls back
into `FT_Load_Glyph' with `FT_LOAD_NO_SCALE' in the flags, which
marks the glyph as `FT_GLYPH_FORMAT_OUTLINE' with an empty path
(even though it doesn't have any path). It appears that the
auto-hinter should not be called when the face doesn't have
outlines. The current test for using the auto-hinter in
`FT_Load_Glyph' checks if the driver supports scalable outlines, but
not if the face supports scalable outlines.
* src/base/ftobjs.c (FT_Load_Glyph): Directly check whether we have
scalable outlines.

[pcf] Replace charmap implementation.
PCF comes with charmap lookup table, aka PCF encodings. Using it
directly makes FT_Get_Char_Index and FT_Get_Next_Char 4-5 times
faster than the original BDF-like binary searches.
* src/pcf/pcf.h (PCF_EncodingRec): Removed.
(PCF_FaceRec): Remove `nencodings' and `encodings'.
* src/pcf/pcfdrivr.c (pcf_cmap_char_{index,next}): Replaced.

* src/sfnt/sfdriver (IS_WIN, IS_APPLE): Omit language ID checks.

(sfnt_get_var_ps_name, sfnt_get_ps_name): Previously we preferred
Win PS name (when there is also an Apple PS name); change this into
a fallback to Apple PS name in case the Win PS name is invalid.
