Applied to master, thanks.

Since frr is a fork from quagga [0], it would not be too surprising that
some of the CVEs against frr were valid back in the quagga era. Also,
Quagga is no longer maintained (as their website is no longer
available). At least, there are three open CVEs:
    CVE-2016-4049
    CVE-2017-3224
    CVE-2021-44038

CVE-2021-44038 was reported after the last quagga release, and that the
two others were not fixed then, but are fixed in frr.

The sole package we have that uses quagga is olsr. Support for quagga
was added in 2013 with commit 9b48690efb59 (olsr: bump to version 0.6.4)
stating "Doesn't really need quagga but not very useful without it", yet
it is still really only optional.

The upstream olsr repository has not had a quagga-related commit since
2019 (commit 385321522335), and the actual last code commit was even
earlier, in 2016, to fix a warning (ac80336d56e5).

Finally, the olsr documentation still mentions old quagga versions that
need to be patched with patches bundled in olsr. Since the upstream
quagga has disapeared, it is not trivial to find whether those patches
were ever upstreamed.

And now that I wrote all the above, it turns out that quagga is not even
a build dependency of olsr at all, so propbably just an optional runtime
dependency.

Which leaves us with just our commit 1e3cd85e7a6d (package/quagga:
install quagga to staging) from Graham, but we have no such in-tree
user, so we can't really assess whether our quagga package is even
installing its dev files properly...

Would it make sense that we now drop Quagga altogether?

If quagga support in olsr is till required, or if third-party code needs
quagga dev files, can that be provided by frr instead?
