baresip,libre: Update to version 3.16.0

[dddaniel]

The previous version 1.1.0 is about 7 years old now and a lot has changed. Various fixes, improvements and features have been added.

The build system has moved to cmake and pkg-config is used, which makes it a lot easier to build from the openwrt buildroot. Therefore a lot of the extra code is removed from the makefiles.

librem is now integrated into libre.

No more patches are required.

Hello Daniel (@dddaniel),

given our limited maintainer capacity, could you at least provide information on the run-tests and confirm whether Baresip can still run after your changes? Just a formal check.

Kind regards,
Jiri

Hi @jslachta, I ran a couple of x86 builds with all plugins enabled. Besides that I am actively using it.

There will be a couple follow up PR's regarding the init script that isn't running in it's current form.
(Also in the previous version, because of a missing user)
In addition I would like to add UCI support for it. The current /etc/default/baresip doesn't integrate well into openwrt.

PR looks good, please take a look at the PKG_RELEASE variables that should reset to 1 after PKG_VERSION change.

Also it would be useful to split the changes into two commits, first libre, then baresip, to keep the history cleaner.

Thank you, Daniel (@dddaniel ). Your PR looks ready to merge. It looks like the test builds are currently broken. I'll check them first and then rerun. If the build succeeds, I’ll proceed with merging your PR.

@dddaniel can you rebase this on top of master?

[jslachta]

Thank you, Christian (@Ansuel), for updating the GitHub workflow.

Hi @jslachta, I just found out during testing that some of the old plugins have been moved to a new repo called baresip-apps.
In order to have all the features available with this update, there needs to be a new package added. So I will close this PR for now and create a new one when it's done.
