HATAYAMA Daisuke 886cf982d3 sysctl: configure kernel parameters in the order they occur in each sysctl configuration files (#4205)
Currently, systemd-sysctl command configures kernel parameters in each sysctl
configuration files in random order due to characteristics of iterator of
Hashmap.

However, kernel parameters need to be configured in the order they occur in
each sysctl configuration files.

- For example, consider fs.suid_coredump and kernel.core_pattern. If
  fs.suid_coredump=2 is configured before kernel.core_pattern= whose default
  value is "core", then kernel outputs the following message:

      Unsafe core_pattern used with suid_dumpable=2. Pipe handler or fully qualified core dump path required.

  Note that the security issue mentioned in this message has already been fixed
  on recent kernels, so this is just a warning message on such kernels. But
  it's still confusing to users that this message is output on some boot and
  not output on another boot.

- I don't know but there could be other kernel parameters that are significant
  in the order they are configured.

- The legacy sysctl command configures kernel parameters in the order they
  occur in each sysctl configuration files. Although I didn't find any official
  specification explaining this behavior of sysctl command, I don't think there
  is any meaningful reason to change this behavior, in particular, to the
  random one.

This commit does the change by simply using OrderedHashmap instead of Hashmap.
