This commit adds some of the missing integer types to stdint.h and adds limit macros (e.g. INTN_{MIN,MAX}). The reference used for adding these types is https://pubs.opengroup.org/onlinepubs/009695399/basedefs/stdint.h.html. We rely on the compiler-defined __LONG_MAX__ to get the right limits for size_t, intptr_t, uintptr_t and ptrdiff_t. This compiler constant seem to have been defined at least since GCC 4.1.2 and clang 3.0.0 on x86_64. It is also defined on ARM (32&64), mips and RISC-V. Note that the maximum size of size_t is implementation-defined (>65535), in this case I chose to go with unsigned long on all platforms since unsigned long == unsigned int on all the platforms we care about. Note that the kernel uses either unsigned int or unsigned long in linux/include/uapi/asm-generic/posix_types.h. These should be equivalent for the plaforms we are targeting. Also note that the 'fast*' flavor of the types have been chosen to be always 1 byte for '*fast8*' and always long (a.k.a. intptr_t/uintptr_t) for the other variants. I have never seen the 'fast*' types in use in the wild but that seems to be what glibc does. Signed-off-by:
