busybox seems to not properly support this option,
and it can be be safely ommitted or replaced
with piping the output through head.

In kdump, if dump-target is ssh on ipv6, we need to sync until ipv6 addr
is ready. Currently ip=auto6/dhcp6 provides such function. But in 1st kernel,
it is hard to know whether the ipv6 addr is got by dhcpv6 or SLAAC.
E.g ifcfg-eth* contains DHCPV6C=yes direction, but there is no dhcpv6
server in the network, and then after the system is up, the user
echo 1 > /proc/sys/net/ipv6/conf/eth0/autoconf && accept_ra by manual
to obtain a ipv6 addr. Or vice.
So this patch suggests to make dhcpv6 as auto6 fallback

Users can pass the DNS information throught "nameserver=" cmdline,
there maybe duplicated inputs.
"/etc/resolv.conf" have some restrictions on the number of DNS items
effective, so make sure that this file contains no duplicated items.
We achieve this by simply making the file have no duplicated lines.

rename iface_has_link() to iface_has_carrier() to clarify usage
Only assign static "wildcard interface" settings, if the interface has a
carrier.
If the interface name was specified with a name, do not do carrier
checking for static configurations.
all_ifaces_up() is true, if all interfaces are up.
all_ifaces_setup() is true, if all interfaces are up and the gateways
and nameserver are setup.

Some hosting providers need a static route set in order to be
able to reach the default gateway. Be sure to retry adding
the default gateway after setting the static routes.
For targets with colons in the iSCSI target name:
"iqn.2000-09.com.foo:storage-system.e2000:00000001cm1p1"
the parser was confused with the optional iscsi_iface_name and
iscsi_netdev_name.
This patch reintroduces the old IQN, EUI and NAA parsing and enhances
the fallback parser by checking the LUN for a numerical value.
In the judgment sentence, it will print the following warning message,
becasuse of lacking the blank on the left of ']'.

When installing OS to a VLAN enabled iscsi LUN (extracted from iBFT), "/tmp/net.{xyz}.has_ibft_config" is not being set properly.
Then anaconda installer requires 'BOOTPROTO="ibft"' populated in ifcfg of the vlan interface (ex: ibft0.20), for it to properly populate the kernel parameters post installation. The setting 'BOOTPROTO="ibft"' is populated by write-ifcfg.sh script only if the corresponding interface has a file /tmp/net.{xyz}.has_inft_config
To get around this issue, in ibft_to_cmdline() function in net-lib.sh file, I made the following changes to populate the has_ibft_config file for the vlan interface(ex: ibft0.20):
By convention, strstr should be a literal string match. Previously, it
would match as a glob pattern. Some code used that, so add new
functions strglob and strglobin to do what that code expects, and
specify them tightly too. strglob tests whether the glob pattern
matches the entire string (the name strglob is also used in the yorick
language, and that's what it does there), while strglobin tests whether
the glob pattern matches anywhere in the string.
Also tightens str_starts, str_ends, and str_replace to deal with
literal strings only. In a quick grep I did not find code that depended
on these functions matching globs.
Changes the call sites where strstr was used with glob patterns to use
strglobin or strglob as the intention seemed to be (or, in one case,
strstr with the * removed as it did not affect the result anyway).
