[gzip] Improve building with external zlib (#49673).
Building FreeType with external zlib 1.2.8 makes msvc 14 stop with
the following error.
ftgzip.c
zlib-1.2.8\zlib.h(86): error C2061:
syntax error: identifier 'z_const'
zlib-1.2.8\zlib.h(94): error C2054:
expected '(' to follow 'z_const'
zlib-1.2.8\zlib.h(94): error C2085:
'msg': not in formal parameter list
...
zlib-1.2.8\zlib.h(877): fatal error C1003:
error count exceeds 100; stopping compilation
The error happens because FreeType keeps an own copy of zlib-1.1.4
under `src/gzip'. When building `src/gzip/ftgzip.c' with
FT_CONFIG_OPTION_SYSTEM_ZLIB defined, it uses
#include <zlib.h>
which correctly finds an external `zlib.h', but `zlib.h' itself has
a line
#include "zconf.h"
which makes Visual Studio 2015 find `src/gzip/zconf.h' while
compiling the files in `src/gzip'.
* src/gzip/zconf.h: Rename to...
* src/gzip/ftzconf.h: ... this.
* src/gzip/zlib.h, src/gzip/rules.mk (GZIP_DRV_SRCS): Updated.

Introduce a way of quickly retrieving (embedded) bitmap metrics.
`FT_Load_Glyph' doesn't generate a bitmap for a non-bitmap glyph
until the user calls `FT_Render_Glyph'. However, it always
allocates memory for bitmaps and copies or decodes the contents of a
bitmap glyph, which can be quite slow for PNG data.
* include/freetype/freetype.h (FT_LOAD_BITMAP_METRICS_ONLY): New
macro.
* src/base/ftobjs.c (FT_Load_Glyph): Unset FT_LOAD_RENDER if
FT_LOAD_BITMAP_METRICS_ONLY is used.
* src/sfnt/ttsbit.c (tt_sbit_decoder_alloc_bitmap,
tt_sbit_decoder_load_bitmap): Add argument to control allocation of
the glyph slot.

[pcf] Enrich family name with foundry name and glyph width info.
This is a very old patch from openSuSE (from 2006, submitted to
FreeType in 2011) that I forgot to apply.
https://build.opensuse.org/package/view_file/openSUSE:Factory/freetype2/freetype2-bitmap-foundry.patch
Prepend the foundry name plus a space to the family name. There are
many fonts just called `Fixed' which look completely different, and
which have nothing to do with each other. When selecting `Fixed' in
KDE or Gnome one gets results that appear rather random, the style
changes often if one changes the size and one cannot select some
fonts at all.
We also check whether we have `wide' characters; all put together,
we get family names like `Sony Fixed' or `Misc Fixed Wide'.
* src/pcf/pcfread.c (pcf_load_font): Implement it.

[truetype] Introduce dynamic limits for some bytecode opcodes.
This speeds up FreeType's handling of malformed fonts.
* src/truetype/ttinterp.c (TT_RunIns): Set up limits for the number
of twilight points, the total number of negative jumps, and the
total number of loops in LOOPCALL opcodes. The values are based on
the number of points and entries in the CVT table.
(Ins_JMPR): Test negative jump counter.
(Ins_LOOPCALL): Test loopcall counter.
* src/truetype/ttinterp.h (TT_ExecContext): Updated.
* docs/CHANGES: Updated.

[truetype] Sanitize only last entry of `loca' table.
Without this patch, a loca sequence like `0 100000 0 100000 ...',
where value 100000 is larger than the `glyf' table size, makes
FreeType handle the whole `glyf' table as a single glyph again and
again, which is certainly invalid (and can be very slow, too).
* src/truetype/ttpload.c (tt_face_get_location): Implement.
Improve tracing messages.

row or a single column of pixels.

build) and `objs/.libs' (for a normal build which uses libtool).

[smooth] Simplify span rendering more.
It turns out that there is significant cost associated with `FT_Span'
creation and calls to `gray_render_span' because it happerns so
frequently. This removes these steps from our internal use but leaves
it alone for `FT_RASTER_FLAG_DIRECT" to preserve API. The speed gain
is about 5%.
* src/smooth/ftgrays.c (gray_render_span): Removed. The code is
migrated to...
(gray_hline): ... here.
