Bug#1112095: recastnavigation: removes symbol without SONAME bump

[Travis Wrightsman]

I am not aware of a specific policy of where to keep embedded libraries.
Although I'm newish to Debian so take that with a grain of salt...

Packages like freebayes include extra embedded external libraries in
debian/ext: https://sources.debian.org/src/freebayes/1.3.9-1/debian/ext

Not sure how accepted this is, but given the context of recast, it seems
at least defendable.

Godot has its own copy of recastnavigation in thirdparty/ so I don't
need to add an extra copy.

In any case, I don't think packages should be fetching sources from the
internet at build time, but I can't find an explicit policy against it.
My understanding was buildd was only recently isolated to more strictly
enforce the no external network access convention at build time, so I
doubt they will revert.

Best,
Travis
