Subject: [PATCH] nft: Use xtables_malloc() in mnl_err_list_node_add()
The function called malloc() without checking for memory allocation
failure. Simply replace the call by xtables_malloc() to fix that.

Subject: [PATCH] ebtables: Dump atomic waste
With ebtables-nft.8 now educating people about the missing
functionality, get rid of atomic remains in source code. This eliminates
mostly comments except for --atomic-commit which was treated as alias of
--init-table. People not using the latter are probably trying to
atomic-commit from an atomic-file which in turn is not supported, so no
point keeping it.

Subject: [PATCH] tests/shell: Assert non-verbose mode is silent
Unexpected output from iptables commands might mess up error-checking in
scripts for instance, so do a quick test of the most common commands.
Note: Test adds two rules to make sure flush command operates on a
non-empty chain.
