Move definition of INTxx_MIN et al to internal header Having the INTxx_MIN et al macros defined in a public header is unnecessary and risky. Also, it wasn't done for all platforms that might need it. So we move those numbers to an internal header file, do the math ourselves and make sure to account for the integer representations we know of. This introduces include/internal, which is unproblematic since we already use -I$(TOP)/include everywhere. This directory is different from crypto/include/internal, as the former is more general internal headers for all of OpenSSL, while the latter is for libcrypto only.

Fix header file include guard names Make the include guards consistent by renaming them systematically according to the naming conventions below For the public header files (in the 'include/openssl' directory), the guard names try to match the path specified in the include directives, with all letters converted to upper case and '/' and '.' replaced by '_'. For the private header files files, an extra 'OSSL_' is added as prefix. Reviewed-by: Richard Levitte <levitte@openssl.org> (Merged from https://github.com/openssl/openssl/pull/9333)

Fix definition of ossl_intmax_t and ossl_uintmax_t These definitions were located away from our definitions of other sized int and uint types. Also, the fallback typedef wasn't quite correct, and this changes it to be aliases for int64_t and uint64_t, since those are the largest integers we commonly handle.
