WIP: Pirania rewrite

[luandro]

This is a re-write of Pirania using nftables, still WIP.

Must haves:

• Open captive portal with Internet
• Block access to Internet
• Permit access to local network
• Working whitelist of macs
• Working whitelist of ips
• Working blocklist of ips
• Working with Ubus
• Working with LimeApp

Looks amazing :D
Compiling an image with this code and OpenWrt 24.10, I observed this warning message:
WARNING: Makefile 'package/feeds/libremesh/pirania/Makefile' has a dependency on 'liblucihttp0', which does not exist
Seems that from the buildroot point of view, that package is named liblucihttp instead of liblucihttp0.

I looked into this: the package is named liblucihttp and is pulled as a dependency of liblucihttp-lua, but there is an ABI_VERSION:=0 thing in the Makefile that causes the 0 to be appended to the package name.

https://github.com/openwrt/luci/blob/d1269d63dae00a0d3611d740bcd1fc77a48f5876/contrib/package/lucihttp/Makefile#L22-L26

So, that warning message seems to be erroneous and everything is actually ok. Is this correct @jow- ?

The source level dependency should be just +liblucihttp - buildroot will take care of turning it into Depends: liblucihttp0 automatically in binary package metadata.

Thanks!!!! I did not see that there was also an explicit dependency from liblucihttp0 in the Makefile!

Adding discovered issues:
1- when enabling portal by limeapp, it does not persiste

2- starting it from console shows an error and it starts to block internet. If voucher system is not enabled, is expected to show captive portal and not to block internet access

# captive-portal start
Command failed: Not found
Failed to parse json data: unexpected end of data
