As different Linux distributions are switching away from iptables
to nftables, this makes it easier to compile CRIU with a different
default network locking backend. Instead of changing the source
code it is now possible to select the nft backend like this:
make NETWORK_LOCK_DEFAULT=NETWORK_LOCK_NFTABLES

The building section also contains the information how to change the network locking backend without source code changes. Signed-off-by: Adrian Reber <[email protected]>
This uses the same formatting for the make command examples as seen in README.md. Signed-off-by: Adrian Reber <[email protected]>

The tests in others/rpc are running as non-root and fail silently if the nftables network locking backend is used. This switches those tests to skip the network locking. Signed-off-by: Adrian Reber <[email protected]>
If the tests in others/rpc are failing no information about that error can be seen in a CI run. This change displays the log files if the test fails. Signed-off-by: Adrian Reber <[email protected]>
There are a couple of tests that require the iptables binary. Instead of adding a checkskip script, which could also handle this, this change now uses CRIU's feature detection to see if the CRIU feature 'has_ipt_legacy' exists. Signed-off-by: Adrian Reber <[email protected]>

@mihalicyn That adds a compile time option to easily switch between backends. |

@danishprakash this is a PR which should help you building RPMs with a different network locking backend. |

This adds the possibility to select a network locking backend during build without the need to change the sources.
It also introduces a test run with iptables uninstalled only relying on nftables.
