Fix some bugs found by clang's `-fsanitize=undefined' (#45661).
* src/base/ftrfork.c (FT_Raccess_Get_HeaderInfo): Only accept
positive values from header.
Check overflow.
* src/base/ftoutln.c (SCALED): Correctly handle left-shift of
negative values.
* src/bdf/bdf.h (_bdf_glyph_modified, _bdf_set_glyph_modified,
_bdf_clear_glyph_modified): Use unsigned long constant.
* src/bdf/bdfdrivr.c (BDF_Size_Select, BDF_Glyph_Load): Don't
left-shift values that can be negative.
* src/pcf/pcfdrivr.c (PCF_Size_Select, PCF_Glyph_Load): Don't
left-shift values that can be negative.
* src/raster/ftraster.c (SCALED): Correctly handle left-shift of
negative values.
* src/sfnt/ttsbit.c (tt_face_load_strike_metrics): Don't left-shift
values that can be negative.
* src/truetype/ttgload.c (TT_Load_Composite_Glyph,
compute_glyph_metrics, load_sbit_image): Don't left-shift values
that can be negative.

[bdf] Fix Savannah bug #34896.
ENCODING now covers the whole Unicode range.
Note, however, that this change is quite expensive since it
increases the size of three arrays by almost 400kByte in total. The
right fix is to replace the logic with something smarter.
Additionally, there exist very old BDFs for three-byte CCCII
encoding which exceeds the range of Unicode (another reason to have
a smarter logic).
* src/bdf/bdf.h (bdf_font_t): Increase size of `nmod' and `umod'
arrays.
* src/bdf/bdflib.c (bdf_parse_t): Increase size of `have' array.

* src/bdf/bdfdrivr.h (BDF_FaceRec): New element `default_glyph'.
* src/bdf/bdflib.c (_bdf_add_property, _bdf_parse_start),
src/bdf/bdf.h (bdf_font_t): s/default_glyph/default_char/.
* src/bdf/bdfdrivr.c (BDF_Face_Init): Fix number of glyphs.
Set `default_glyph'.
(BDF_Glyph_Load): Use `default_glyph' for undefined glyph.
* docs/CHANGES: Updated.

* src/bdf/bdflib.c (hash_bucket, hash_lookup): Use `const' for first
argument.
(bdf_get_font_property): Use `const' for third argument.
Updated all callers.
* src/bdf/bdfdrivr.c (BDF_Face_Init): Set pixel width and height
similar to the PCF driver.
* src/bdf/bdf.h (_hashnode): Use `const' for `key'.
Updated.
* src/gzip/ftgzip.c: C++ doesn't like that the array `inflate_mask'
is declared twice. It is perhaps better to modify the zlip source
files directly instead of this hack.
(zcalloc, zfree, ft_gzip_stream_close, ft_gzip_stream_io): Add casts
to make build with g++ successful.

* src/type42/t42drivr.c: s/T42_ENCODING_TYPE_/T1_ENCODING_TYPE_/.
(parse_font_matrix): Remove unnecessary code.
(parse_sfnts): Initialize some variables.
(t42_driver_class) [TT_CONFIG_OPTION_BYTECODE_INTERPRETER]: Use
ft_module_driver_has_hinter conditionally.
Moved some type 42 specific structure definitions to...
* include/freetype/internal/t42types.h: New file.
* include/freetype/internal/internal.h (FT_INTERNAL_T42_TYPES_H):
New macro.
* include/freetype/cache/ftcsbits.h (FTC_SBit): Added a new field
`num_grays' for specifying the number of used gray levels.
* src/cache/ftcsbits.c (ftc_sbit_node_load): Initialize it.
Adding a driver for BDF fonts written by Francesco Zappa Nardelli
<Francesco.Zappa.Nardelli@ens.fr>. Heavily modified by me to
better adapt it to FreeType, removing unneeded stuff. Additionally,
it now supports Mark Leisher's BDF extension for anti-aliased
bitmap glyphs with 2 and 4 bpp.
* src/bdf/*: New driver.
* include/freetype/internal/bdftypes.h: New file.
* include/freetype/internal/fttrace.h: Added BDF driver components.
* include/freetype/fterrdef.h: Added error codes for BDF driver.
* include/freetype/config/ftmodule.h, src/Jamfile: Updated.
* include/freetype/internal/internal.h (FT_INTERNAL_BDF_TYPES_H):
New macro.
* include/freetype/config/ftstdlib.h (ft_sprintf): New alias for
sprintf.
* include/freetype/internal/fttrace.h: Added Type 42 driver
component.
* src/type42/t42drivr.c: Use it.
* include/freetype/internal/internal.h (FT_INTERNAL_PCF_TYPES_H):
New macro.
