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", }; $
