  1. tests: 64 bit compatibility 

    Fixed compilation errors. Mostly DEBUG/printf formatting and void pointer casting.

Other changes are:
* net/gnrc_sixlowpan_frag_*: Generalized packet size calculation
* cpu/native_backtrace: Reduced required backtrace size to 3 for 64-bit
* periph/flashpage: Simplified test
* unittests/tests-pktbuf: Generalized alignment
* sys/architecture: Extended test for 64-bit

  3. native: 64 bit compatibility and Linux/x86_64 support for the native 

    Initial version to test 64 bit compatibility.

Instead of a separate board, 64 bit for Linux/x86_64 is enabled by setting the environment variable `NATIVE_64BIT=y` and compiling as usual.
While I personally prefer a separate `native64` board, this ensures that all tests run with the same configuration as the 32 bit version.
A separate board would require a major refactoring of many tests, which often have special behavior for the native board,
and I didn't want to increase the size of an already large pull request.

Not currently implemented:
* Architectures other than x86_64 or operating systems other than Linux
    * No FreeBSD support
    * No Aarch support
* Rust support for x86_64
