net-lib.sh is a library of useful functions for network stuff.
More things may get added/moved here in the future.

if you add realinitpath="<path1> <path2>" to dracut.conf, then it will
be written to $initdir/etc/cmdline.d/distroinit.conf with
"rd.distroinit=<path1> rd.distroinit=<path2>" and evaluated by
99base/init, when it searches for init.
Current dracut network only will be setup when netroot is used. But there are
some cases we need network even without netroot. For example kdump will need
copy vmcore to remote machine via scp or nfs mount. OTOH, if we use dracut as
a recovery system the network is helpful even root is not a network device.
This implementation is based on the manually bring up method. Here add a kernel
cmdline argument rd.neednet. If rd.neednet is set dracut will bring up network
with ifup $INTERFACE -m. If netroot is used we still keep original behavior.

fstab-sys will mount nonroot nfs as well, so we need to split the necessary
code from nfsroot to start rpc daemon as hook script.

If /etc/fstab.sys does not exist installing fstab-sys module will fail.
Fix this by checking use_fstab and fstab_lines as well

For kdump we need scp vmcore to remote machine, the nic to be used is
not limited to netroot one. we need a feature for manually bringing up
network interface. Also it is useful for emergency shell with
ssh-client for recovery or test purpose
I implement this by adding one argument to ifup script, user can use
`/sbin/ifup eth0 -m` to bring up eth0, note ifup will regard it a
manual operation for the nic specified in 1st argument if there's
the 2nd argument.
If same nic is used for netroot the 2nd argument will be ignored,
in this case we will leave netroot bring up it automatically to
avoid side effect. And in this case hooks such as kdump will need to
execute after netroot mounted.
`ifup eth0 -m` will create /tmp/net.eth0.manualup stamp file,
later dhclient-script can check this and pass $2 to netroot,
then netroot script will bring eth0 up
Thanks for comments and suggestions from David Dillow.

First, $host_fs_types is an array.
Second, use strstr to match btrfs type.
