perf beauty: Add a generator for IPPROTO_ socket's protocol constants
It'll use tools/include copy of linux/in.h to generate a table to be
used by tools, initially by the 'socket' and 'socketpair' beautifiers in
'perf trace', but that could also be used to translate from a string
constant to the integer value to be used in a eBPF or tracefs tracepoint
filter.
When used without any args it produces:
$ tools/perf/trace/beauty/socket_ipproto.sh
static const char *socket_ipproto[] = {
[0] = "IP",
[103] = "PIM",
[108] = "COMP",
[12] = "PUP",
[132] = "SCTP",
[136] = "UDPLITE",
[137] = "MPLS",
[17] = "UDP",
[1] = "ICMP",
[22] = "IDP",
[255] = "RAW",
[29] = "TP",
[2] = "IGMP",
[33] = "DCCP",
[41] = "IPV6",
[46] = "RSVP",
[47] = "GRE",
[4] = "IPIP",
[50] = "ESP",
[51] = "AH",
[6] = "TCP",
[8] = "EGP",
[92] = "MTP",
[94] = "BEETPH",
[98] = "ENCAP",
};
