[GSoC] src/*.*: Convert block comments to `light' style. This monster commit was created by applying Nikhil's scripts `docconverter.py' and `markify.py' to all C header and source files, followed up by minor manual clean-up. No change in functionality, of course. I used commit f7419907bc6044b9b7057f9789866426c804ba82 from https://github.com/nikramakrishnan/freetype-docs.git.

[autofit] Split `afwrtsys.h`. The header file `afwrtsys.h` has two distinct functions: to include the required writing system headers and also to generate code for each writing system. At each current use site only one or the other is used, with various macro trickery selecting one or the other. Split this header into `afws-decl.h` for the required writing system declarations and `afws-iter.h` for iterating over the writing systems to generate code. The motivation for this change is that the Visual C++ compiler treats the standard include guard idiom like `#pragma once` 'if no non-comment code or preprocessor directive comes before or after the standard form of the idiom'. It appears to check this after macro expansion, so if `WRITING_SYSTEM` expands to empty the bottom of `afwrtsys.h` is empty and looks like the standard include guard idiom which is treated like `#pragma once`, so subsequent inclusion of `afwrtsys.h` is elided. Fixes #1075. * src/autofit/afglobal.c (af_writing_system_classes), src/autofit/aftypes.h (AF_WritingSystem), src/autofit/rules.mk (AUTOF_DRV_H): Updated. * src/autofit/afwrtsys.h: Split into... * src/autofit/afws-decl.h, src/autofit/afws-iter.h: New files.

Introduce `coverages'. Coverages are the interface to the HarfBuzz library to access OpenType features for handling glyphs not addressable by the cmap. Right now, compilation of HarfBuzz is only added to the development build. A solution for standard build mode will be delayed until HarfBuzz gets split into two libraries to avoid mutual dependencies between FreeType and HarfBuzz. Note that this is only a first step in handling coverages, basically providing the framework only. Code for handling selected OpenType features (this is, actually using the data in `afcover.h') will follow. * devel/ftoption.h, include/config/ftoption.h (FT_CONFIG_OPTION_USE_HARFBUZZ): New macro. * src/autofit/hbshim.c, src/autofit/hbshim.h, src/autofit/afcover.h: New files. * src/autofit/afscript.h: Add HarfBuzz script name tags. * src/autofit/afstyles.h: Add default coverage enumeration values. * src/autofit/aftypes.h: Update use of `SCRIPT' and `STYLE' macros. (AF_Coverage): New enumeration (generated by `afcover.h'). (AF_StyleClassRec): New member `coverage'. (AF_DEFINE_STYLE_CLASS): Updated. * include/internal/fttrace.h: Add `afharfbuzz' for tracing coverage data. * src/autofit/afglobal.h: Update use of `SCRIPT' and `STYLE' macros. (AF_SCRIPT_FALLBACK): Renamed to ... (AF_STYLE_FALLBACK): ... this. * src/autofit/afglobal.c: Include `hbshim.c'. Update use of `SCRIPT' and `STYLE' macros. (af_face_globals_compute_style_coverage) [FT_CONFIG_OPTION_USE_HARFBUZZ]: Call `af_get_coverage'. Update. * src/autofit/afmodule.h (AF_ModuleRec): s/fallback_script/fallback_style/. * src/autofit/afmodule.c (af_property_set): Adapt handling of `fallback-script' property to set a fallback style. (af_property_get, af_autofitter_init): Updated. * src/autofit/afpic.c: Update use of `SCRIPT' and `STYLE' macros. * src/autofit/afranges.h: Update use of `SCRIPT' macro. * src/autofit/autofit.c [FT_CONFIG_OPTION_USE_HARFBUZZ]: Include `hbshim.c'. * src/autofit/rules.mk (AUTOF_DRV_SRC): Add `hbshim.c'. (AUTOF_DRV_H): Add `afcover.h'. * builds/freetype.mk (INCLUDE_FLAGS) [DEVEL_DIR]: Use pkg-config for all libraries needed by FreeType.
