fxlibc - v1.4.2 : fix reallocarray() + remove old Vhex/Casiowin sources
@update > CMakeLists.txt | remove casiowin-* target (unused) | remove x86-generic target (unused) | update files location | remove old vhex sources files (deprecated, unused) > src/posix | remove this folder > src/libc | move its content to src/ | remove thread module > src/stdlib/reallocarray | check if the multiplication overflow failed | set appropriate errno value if multiplication failed
