This partial patch reverts:
ccc5da470e76 ("datatype: Replace getnameinfo() by internal lookup table")
f0f99006d34b ("datatype: Replace getaddrinfo() by internal lookup table")
so /etc/services is used to interpret service names, eg.
# nft add rule x y tcp dport \"ssh\"
Then, listing looks like:
# nft list ruleset -l
table x {
chain y {
...
tcp dport "ssh"
}
}
Major changes with regards to the original approach are:
1) Services are displayed in text via `-l' option.
2) Services are user-defined, just like mappings in /etc/iproute2/*
files and connlabel.conf, so they are displayed enclosed in quotes.
Note that original service name code was broken since it parses both udp
and tcp service names but it only displays tcp services names as
literal. This is because NI_DGRAM is missing. This patch makes nft falls
back on udp services if no literal was found in the initial tcp service
name query. Proper way to handle would be to add infrastructure to store
protocol context information in struct output_ctx.

because the convention is to represent ports in base 10.
gcc-workaround is no longer needed and was removed.

To avoid exceeding the inputs number limit of the flex scanner used,
when calling getnameinfo() in inet_service_type_print().
The new symbol_table was associated with inet_service_type, to enable
listing all pre-defined services using nft command line tool.
The listed services are all well-known and registered ports of my
local /etc/services file, from Ubuntu 16.04. Service numbers are
converted to respect network byte order.
