This patch turns on POSIXLY_CORRECT on the getopt parser to enforce
options before commands. Users get a hint in such a case:
# nft list ruleset -a
Error: syntax error, options must be specified before commands
nft list ruleset -a
^ ~~
This patch recovers 9fc71bc6b602 ("main: Fix for misleading error with
negative chain priority").
Tests have been updated.

Future change is going to auto-change them to simple compare
ops rather than lookup in set with only one element.

bash 4.3.30 removes newlines in RULESET when "" are omitted, which
then causes nft -f to complain about invalid syntax.
As a result, all test cases that use this here-doc style fail.

Two reports point to a crash in nft when 'flush' is provided
on existing ruleset. In that case, nft will crash with a null-ptr
dereference.
"evaluate: do not inconditionally update cache from flush command"
causes the commit to fail due to a cache inconsistency, we then trip
over NULL location->indesc. Cause of 2nd bug not known yet, not sure
how to fix cache issue either, so only adding reproducer so this can be
fixed later.
Without erec bug, the (errnoeous) error message would be
Could not process rule: File exists

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.
