cmake: build executables by driving cargo directly Drops the requirement for Corrosion, as almost none of its extensive features are required.

cmake: add support for vendored cmake Use a "cmake-vendored" directory if it exists, to avoid accessing the network if it's available, and a target to create an appropriate tarball to create that directory.

Remove a CMake 3.19 construct CONFIG supports multiple arguments only as of CMake 3.19, see https://cmake.org/cmake/help/latest/manual/cmake-generator-expressions.7.html#configuration-expressions Ubuntu focal ships with 3.16 by default, so enable building with that. Note that there is also the workaround of installing "cmake-mozilla".

Add rsconf build system and check for gettext symbols This is more complicated than it needs to be thanks to the presence of CMake and the C++ ffi in the picture. rsconf can correctly detect the required libraries and instruct rustc to link against them, but since we generate a static rust library and have CMake link it against the C++ binaries, we are still at the mercy of CMake picking up the symbols we want. Unfortunately, we could detect the gettext symbols but discover at runtime that they weren't linked in because CMake was compiled with `-DWITH_GETTEXT=0` or similar (as the macOS CI runner does). This means we also need to pass state between CMake and our build script to communicate which CMake options were enabled.
