We also need to clear expr ctx before we eval a command.
This is a followup fix to 'evaluate: reset eval context when evaluating
set definitions'.
The first patch only fixed set evaluation when dealing with
a complete table representation rather than individual commands.

David reported nft chokes on this:
nft -f /tmp/A
/tmp/A:9:22-45: Error: datatype mismatch, expected concatenation of (IPv4 address, internet network service, IPv4 address), expression has type concatenation of (IPv4 address, internet network service)
cat /tmp/A
flush ruleset;
table ip filter {
set setA {
type ipv4_addr . inet_service . ipv4_addr
flags timeout
}
set setB {
type ipv4_addr . inet_service
flags timeout
}
}
Problem is we leak set definition details of setA to setB via eval
context, so reset this.
Also add test case for this.

In libnftables, detect if given filename is '-' and treat it as the
common way of requesting to read from stdin, then open /dev/stdin
instead. (Calling 'nft -f /dev/stdin' worked before as well, but this
makes it official.)
With this in place and bash's support for here strings, review all tests
in tests/shell for needless use of temp files. Note that two categories
of test cases were intentionally left unchanged:
- Tests creating potentially large rulesets to avoid running into shell
parameter length limits.
- Tests for 'include' directive for obvious reasons.

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.

This new datatype is a string subtype.
It will allow us to build named maps/sets using meta keys like 'iifname',
'oifname', 'ibriport' or 'obriport'.
Example:
table inet t {
set s {
type ifname
elements = { "eth0",
"eth1" }
}
chain c {
iifname @s accept
oifname @s accept
}
}

Previously, when adding multiple ranges to a set they were merged if
overlapping or adjacent. This might cause inconvenience though since it
is afterwards not easily possible anymore to remove one of the merged
ranges again while keeping the others in place.
Since it is not possible to have overlapping ranges, this patch adds a
check for newly added ranges to make sure they don't overlap if merging
is turned off.
Note that it is not possible (yet?) to enable range merging using nft
tool.
Testsuite had to be adjusted as well: One test in tests/py changed avoid
adding overlapping ranges and the test in tests/shell which explicitly
tests for this feature dropped.

According to bugzilla 1137: "flow tables" should not be syntactically
unique.
"Flow tables are always named, but they don't conform to the way sets,
maps, and dictionaries work in terms of "add" and "delete" and all that.
They are also "flow tables" instead of one word like "flows" or
"throttle" or something.
It seems weird to just have these break the syntactic expectations."
Personally, I never liked the reference to "table" since we have very
specific semantics in terms of what a "table" is netfilter for long
time.
This patch promotes "meter" as the new keyword. The former syntax is
still accepted for a while, just to reduce chances of breaking things.
At some point the former syntax will just be removed.

Before c6cd7c22548a ("src: fix crash when inputting an incomplete set
add command") commit, if we run nft with incomplete "add set" command it
caused segmentation fault and exit with error code 139 and further it
didn't throw any error message.
For example:
$ sudo nft add set t s
But after the aforementioned commit it throws syntax error message and
exits with return value 1.
For example:
$ sudo nft add set t s
<cmdline>:1:12-12: Error: syntax error, unexpected newline, expecting '{'
add set t s

Not having a space between the last element in a set and the closing
curly brace looks ugly, so add it here.
This also adjusts all shell testcases as they match whitespace in nft
output and therefore fail otherwise.
