[cff, pfr, psaux, winfonts] Fix Savannah bug #43676.
Don't cast cmap init function pointers to an incompatible type.
Without this patch, the number of parameters between declaration and
the real signature differs. Calling such a function results in
undefined behavior.
ISO/IEC 9899:TC3 (Committee Draft September 7, 2007)
6.5.2.2 Function calls
9 If the function is defined with a type that is not
compatible with the type (of the expression) pointed to by
the expression that denotes the called function, the
behavior is undefined.
On certain platforms (c -> js with emscripten) this causes
termination of execution or invalid calls because in the emscripten
implementation, function pointers of different types are stored in
different pointer arrays. Incorrect pointer type here results in
indexing of an incorrect array.

Avoid compiler warnings on x86-64 for `FT_MulFix'.
`FT_MulFix' takes `FT_Long' parameters as defined in `freetype.h',
but several inline implementations of it in `ftcalc.h' take
`FT_Int32' arguments. This is causing compiler warnings on x86-64:
If parameters of type `FT_Fixed' (= `FT_Long') are passed to the
inline implementation of this function, integer values are truncated
from 64bit to 32bit.
* include/internal/ftcalc.h (FT_MulFix) [FT_MULFIX_ASSEMBLER]: Add

Before this patch, it was impossible to ever call DELTAP[123] in

only worked if in `compatibility mode'. However, compatibility mode
essentially disables SHPIX, completely ruining hinting of
ttfautohint output, for example.

instructions for touched points in the non-subpixel direction are
executed.

macros when available, do not check for non-zero distance.

if sign changed.

[autofit] Add blue-zone support for Telugu.
This essentially moves the Telugu script from the `Indic' hinter to
the `Latin' hinter.
Note that this is a first shot and quite certainly needs
refinements.
* src/autofit/afblue.dat: Add blue zone data for Telugu.
* src/autofit/afblue.c, src/autofit/afblue.h: Regenerated.
* src/autofit/afscript.h: Add Telugu standard characters and move
data out of AF_CONFIG_OPTION_INDIC block.
* src/autofit/afranges.c: Move Telugu data out of
AF_CONFIG_OPTION_INDIC block.
* src/autofit/afstyles.h: Update Telugu data; in particular, use
AF_WRITING_SYSTEM_LATIN.

A better fix for Savannah bug #43392.
Suggested by Doug Felt <dougfelt@gmail.com>.
* src/sfnt/ttsbit.c (tt_sbit_decoder_load_metrics): Set
`vertAdvance' to zero...
* src/truetype/ttgload.c (TT_Load_Glyph): ... and set here a default
value for `vertAdvance' based on `linearVertAdvance' in case
`vertAdvance' is zero. Note that the previous computed ad-hoc value
for `linearVertAdvance' was apparently not tested in a real-life
situation.

[base] Significant optimization of `ft_div64by32'
We shift as many bits as we can into the high register, perform
32-bit division with modulo there, then work through the remaining
bits with long division. This optimization is especially noticeable
for smaller dividends that barely use the high register.
* src/base/ftcalc.c (ft_div64by32): Updated.
