wireguard.cgi: Normalize filenames
This is because Windows clients won't import any configurations that
have spaces in the filename. Therefore we replace it and remove anything
else unwanted on the way.

pwru is an utility to trouble shoot network issue,
and to speed up pwru kprobe attachement, kernel needs
to have CONFIG_FPROBE.
running pwru also result in:
Opening kprobe-multi: invalid argument \
(missing kernel symbol or prog's AttachType not AttachTraceKprobeMulti?)
need following to avoid above invalid argument
echo -1 > /proc/sys/kernel/perf_event_paranoid
echo 0 > /proc/sys/kernel/kptr_restrict

UDP DDoS has pattern of flooding game server with
random source IP and UDP with random payload. game
server UDP traffic requires certain payload
pattern, so this XDP program can serve as example
to stop UDP DDoS attack with UDP payload that does not
match game UDP traffic payload pattern.
without UDP DDoS protection, under DDoS attack:
BPFire UI RED Traffic: in 9xx Mbit/s.
with UDP DDoS protection, under DDoS attack:
BPFire UI RED Traffic: in 1xx Mbit/s.

suricata XDP support requires xdp-tools with
libbpf 1.4 to resolve stack smash issue.
also workaround memlock operation not permitted
by running suricata as root since load/attach
XDP program requires root privilige anyway.
see: https://github.com/vincentmli/BPFire/issues/54
Usage scenario:
since suricata IPS XDP capture mode works as
layer 2 bridge, BPFire netfilter firewall, NAT
IP route will be bypassed. no IP address should
be assigned to red0 and green0 interface.
172.16.1.0/24 inline 172.16.1.0/24
red network<-->red0(xdp)<-->green0(xdp)<-->green network
we can run setup command to assign IP/Mask 0.0.0.0/0.0.0.0
to red0 and green0, then reboot BPFire, BPFire DHCP
will stops working after reboot. green network client
can get DHCP IP from upstream dhcp server.
start suricata manually
suricata -c /etc/suricata/suricata-xdp.yaml --af-packet
xdp_filter.bpf program will be attached to red0 and gree0
interface
not sure if we should add GUI for suricata XDP capture mode
since this is not common use case.

add the missing config/cfgroot/xdpdns-settings file
and use ENABLE_DNSBLOCK=on by default, so XDP DNS
Blocklist is enabled by default.
also add domainfile so when BPFire reboot first time
and when xdpdns init startup, it will not complain
missing domainfile
