Massive clang-format of every C or C++ source file (*.h, *.c, *.cpp), except for: + third_party/ + ext/drsysm/libelftc/include/ + ext/drsyms/demangle.cc This is a single, large commit by design to present a single history disruption point and bring the code base into a consistent format. clang-format version 6.0 was used. Tweaks the clang-format rules to indent 4 after pre-processor hashes, to allow single-line case labels, and align trailing comments. Disables the pp_indent vera style check as we changed the indent rule and clang-format now covers it. Leaves the other checks, even though some are redundant (they found clang-format errors). Moves C++ token defines from globals_shared.h and globals.h to a new header, core/lib/c_defines.h, to avoid a clang-format parsing error where it fails to identify the include guard. Adds genapi.pl removal of extra indentation inside API_EXPORT_ONLY and CLIENT_INTERFACE regions. Adds exclusions around large regions we don't want to format, in these files: + core/win32/syscallx.h + core/arch/x86/decode_table.c + core/arch/arm/table_a32_pred.c + core/arch/arm/table_a32_unpred.c + core/arch/arm/table_t32_16.c + core/arch/arm/table_t32_16_it.c + core/arch/arm/table_t32_base.c + core/arch/arm/table_t32_coproc.c + core/arch/arm/table_encode.c Adds smaller exclusions to work around clang-format bugs: + Several missing break-after-return-type + Several >90-char lines + Misc scattered issues, all listed in #2876 Issue: #2876
