tc-basic-classifier: fix tcp port Endianess bug by AI
AI generated class_filter program stored the tcp port in network order,
but in bpf program the tcp port is converted to host order, and result in
tcp port lookup failure, unable to get the correct classid, fail to do rate
classification.

tc-basic-classifier: classify port and IP from bpf map
add port and IP rate classification based on bpf map so user could
add or remove port/IP rate classification dynamically at run time
since TC class works on egress direction, so port rate classification
works on red0 egress, and IP rate classification works on green0 egress
port rate classification:
class_filter -a -b ./class_filter.bpf.o -i red0 -v
class_filter -i red0 --add-port 8080:10:80mbit
class_filter -i red0 --add-port 8081:20:40mbit
class_filter -i red0 --delete-port 8080
class_filter -i red0 --list-ports
IP rate classification:
class_filter -a -b ./class_filter.bpf.o -i green0 -v
class_filter -i red0 --add-ip 192.168.1.0/24:40:30mbit
class_filter -i red0 --delete-ip 192.168.1.0/24
class_filter -i red0 --list-ips

tc-basic-classifier: add user space program
the bpf skel header is generated only if USER_TARGETS
is added in Makefile, so add a dummy user space program.

How to build BPFire?
Build Environment Setup https://www.ipfire.org/docs/devel/ipfire-2-x/build-initial
(It takes a few hours to build image for first build depending on build machine power)
for example on Ubuntu 22.04 LTS:
apt install git-core g++ manpages-pl patch byacc make autoconf automake libltdl-dev
git clone https://github.com/vincentmli/bpfire.git
cd bpfire
wget --mirror --convert-links --adjust-extension --page-requisites --no-parent --cut-dirs=2 -nH --reject "index.html*" --reject "*.gif" https://www.bpfire.net/download/bpfire/cache/
