Antonio SJ Musumeci 0cfab60f37 replace raw C-strings with std::string in converted libfuse files 
util/mount.mergerfs.cpp:
- Remove xstrdup/xrealloc wrappers entirely
- Convert type, source, options, command, setuid to std::string
- Replace add_arg() pointer-rewriting with shell_quote() returning std::string
- Replace add_option() with simple std::string += concatenation
- Fix const_cast UB on string literal assignment

lib/helper.cpp:
- Convert add_default_subtype local subtype_opt: malloc+snprintf+free -> std::string construction

lib/mount_generic.h:
- Convert fuse_mount_sys locals source/type: malloc+strcpy+strcat -> std::string
- Remove 4 unnecessary free() calls (RAII cleanup)
- .c_str() at mount() and fuse_mnt_add_mount() boundaries

lib/mount_util.h:
- Rewrite fuse_mnt_resolve_path internals using std::string: rfind/substr
  instead of manual pointer arithmetic, strrchr, strlen chains

Antonio SJ Musumeci 21966ade97 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
