Now that we keep track of more payload dependencies, more redundant
payloads are eliminated. Remove these from the shell test-cases.

Reset temporary stmt list to deal with the key_end case which might
result in a jump backward to handle the rhs of the interval.

If the map is anonymous, infer it from the set elements. Otherwise, the
set definition already have an explicit concatenation definition in the
data side of the mapping.
This update simplifies the NAT mapping syntax with concatenations, e.g.
snat ip to ip saddr map { 10.141.11.4 : 192.168.2.3 . 80 }

expr_evaluate_concat() is overloaded, it deals with two cases:
#1 set key and data definitions, this case uses the special
dynamically created concatenation datatype which is taken
from the context.
#2 set elements, this case iterates over the set key and data
expressions that are components of the concatenation tuple,
to fetch the corresponding datatype.
Add a new function to deal with case #1 specifically.
This patch is implicitly fixing up map that include arbitrary
concatenations. This is failing with a spurious error report such as:
# cat bug.nft
table x {
map test {
type ipv4_addr . inet_proto . inet_service : ipv4_addr . inet_service
}
}
# nft -f bug.nft
bug.nft:3:48-71: Error: datatype mismatch, expected concatenation of (IPv4 address, Internet protocol, internet network service), expression has type concatenation of (IPv4 address, internet network service)
type ipv4_addr . inet_proto . inet_service : ipv4_addr . inet_service
^^^^^^^^^^^^^^^^^^^^^^^^

'verdict' cannot be used as part of a map typeof-based key definition,
its a datatype and not an expression, e.g.:
typeof iifname . ip protocol . th dport : verdic
... will fail.
Make the parser convert a 'verdict' symbol to a verdict expression
and allow to store its presence as part of the typeof key definition.

set->data from implicit_set_declaration(), otherwise, set_evaluation()
bails out with:
# nft -f /etc/nftables/inet-filter.nft
/etc/nftables/inet-filter.nft:8:32-54: Error: map definition does not specify
mapping data type
tcp dport vmap { 22 : jump ssh_input }
^^^^^^^^^^^^^^^^^^^^^^^
/etc/nftables/inet-filter.nft:13:26-52: Error: map definition does not specify
mapping data type
iif vmap { "eth0" : jump wan_input }
^^^^^^^^^^^^^^^^^^^^^^^^^^^
Add a test to cover this case.

Pablo reports following list bug:
table ip foo {
map whitelist {
typeof ip saddr . ip daddr : meta mark
elements = { 0x0 [invalid type] . 0x0 [invalid type] : 0x00000001,
0x0 [invalid type] . 0x0 [invalid type] : 0x00000002 }
}
}
Problem is that concat provided 'invalid' dtype.

Add sets using unspecific string/integer types, one with
osf name, other with vlan id. Neither type can be used directly,
as they lack the type size information.

Complete the automated shell tests with the verification of
the test file dump, only for positive tests and if the test
execution was successful.
It's able to generate the dump file with the -g option.
Example:
# ./run-tests.sh -g testcases/chains/0001jumps_0
The dump files are generated in the same path in the folder named
dumps/ with .nft extension.
It has been avoided the dump verification code in every test
file.
