Convert vendored/libfuse C sources to C++17
Convert all C source files in vendored/libfuse/ to C++17:
- lib/crc32b.c -> crc32b.cpp (const void* cast)
- lib/fuse_opt.c -> fuse_opt.cpp (designated init, void* arithmetic)
- lib/fuse_signals.c -> fuse_signals.cpp
- lib/helper.c -> helper.cpp (void* data cast)
- lib/mount.c -> mount.cpp (thin wrapper)
- lib/mount_generic.c -> mount_generic.h (static inline, #pragma once)
- lib/mount_bsd.c -> mount_bsd.h (static inline, #pragma once)
- lib/mount_util.c -> mount_util.h (static inline, #pragma once)
- util/fusermount.c -> fusermount.cpp
- util/mount.mergerfs.c -> mount.mergerfs.cpp
Key changes:
- Replace C99 designated initializer in fuse_opt_parse with field-by-field init
- Fix void* pointer arithmetic via char* base + offset pattern
- All C-style (T*)voidptr casts replaced with static_cast/reinterpret_cast
- Remove redundant #define _GNU_SOURCE (already in FUSE_FLAGS)
- Wrap __clone2 declaration in extern "C" for ia64 path
- Update Makefile: empty SRC_C, build utils with $(CXX) instead of $(CC)
- Remove stale .c files now replaced by .cpp/.h counterparts
All binaries build cleanly: mergerfs, mergerfs-fusermount, mount.mergerfs
