iproute2: backport json_print-fix-hidden-64-bit-type-promotion
The sender domain has a DMARC Reject/Quarantine policy which disallows sending mailing list messages using the original "From" header. To mitigate this problem, the original message has been wrapped automatically by the mailing list software. print_uint() will silently promote its variable type to uint64_t, but there is nothing that ensures that the format string specifier passed along with it fits (and the function name suggest to pass "%u"). Fix this by changing print_uint() to use a native 'unsigned int' type, and introduce a separate print_u64() function for printing 64-bit values. All call sites that were actually printing 64-bit values using print_uint() are converted to use print_u64() instead. Since print_int() was already using native int types, just add a print_s64() to match, but don't convert any call sites.
