Create and use FMT* macros that are equivalent to the PRI* macros that inttypes.h defines. This allows uniform use of the Unix-specific format specifiers, e.g. "%zu", as well as avoiding Windows-specific definitions of e.g. PRIu64. Add ffs()/ffsl() support for compiling with gcc. Extract compatibility definitions of ENOENT, EINVAL, EAGAIN, EPERM, ENOMEM, and ENORANGE into include/msvc_compat/windows_extra.h and use the file for tests as well as for core jemalloc code.
