libwebsockets: Add full-libevent variant

[Matthiasfranck]

Adds a new libwebsockets-full-libevent package. This package adds support for libevent on top of the already existing libwebsockets-full package.

Maintainer: @karlp Compile tested: (put here arch, model, OpenWrt version) Run tested: (put here arch, model, OpenWrt version, tests done)

Description:

[karlp]

Does this really justify another package? what are the users of libevent, and is libwebsockets actually maintaining this one? what's the size impact of just adding libevent support into the existing "full" ?

[Matthiasfranck]

Hi @karlp, you can check the discussion here: https://github.com/openwrt/packages/issues/21157

We use libwebsockets with libevent in prplos (https://gitlab.com/prpl-foundation/prplos/prplos)

@karlp @Matthiasfranck still relevant? If so this needs a PKG_RELEASE bump and to reformat the commit message according to the submission guidelines.
