941d7c51d7 implement execution timeouts for executors 
Previously, it was possible for an executor to hang forever.  To mitigate
this, we now implement process execution timeouts for executors, by looping
with waitpid(..., WNOHANG) and sleeping.

This could be implemented more efficiently with process descriptors, see
pidfd_open(2), but that interface is Linux-specific and is only available
on Linux 5.3 or newer.

480fc5eecb compat: Only create interface when configured to do so. 
Add config option <compat_create_interfaces>:

  Denotes where or not to create interfaces when compat_* settings are
  active and it would be necessary to create an interface to be fully
  compliant.  This could happen when inheriting bridge VLAN settings to
  an interface within a bridges bridge-ports setting but no interface
  stanza is found.  Valid values are 0 and 1, the default is 1.

d86297f29c compat: Add glue for ifupdown2 bridge port VLAN inheritance. 
Add config options <compat_ifupdown2_bridge_ports_inherit_vlans>.

  In ifupdown2 <bridge-vids> as well as the <bridge-pvid> set on a bridge
  interface will be inherited by all member ports if not set explicitly.
  When set to 1 ifupdown-ng behaves the same way and will internally copy
  both options from the bridge member ports if they are not set on the
  member port. Valid values are 0 and 1, the default is 1.

de207a5950 lifecyle: Use lif_address_format_cidr() for IF_ADDRESSES 
Previously IF_ADDRESSES would not contain a prefix length if the address
  entry in the configuration did not was in CIDR format but had a netmask
  set seperately. This commit fixes that behaviour and computes a CIDR
  netmask if necessary.
