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
