This adds nfs_fetch_url to allow fetching arbitrary files from NFS.
This means that livenet can now run using an NFS-mounted live image,
which reduces memory usage by a lot.

This makes the livenetroot module use url-lib for fetching its root
image/filesystem. There's also some minor tweaks for POSIX compliance.

url-lib adds some functions for dealing with URLs (mostly for fetching
files, for the moment).
It uses curl to handle http/https/ftp URLs, but it can be extended by other
modules at runtime by using the "add_url_handler" function.

nfs-lib.sh contains a bunch of functions used to parse NFS "url"s of
various types, pull nfs information out of dhcp info, and actually
perform nfs mounts sanely.

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.
