Back when specific control of the Rust version used with RIOT was
needed, CARGO_CHANNEL was added to explicitly set the Rust version with
consideration for CI special cases.
Rust's mechansims of selecting a toolchain can be used instead now.
If `register_interrupt` somehow fails, we leak the already created
POSIX timer by returning immediately.
Fix this by calling `timer_delete` before returning.

When using `err`, no stacktrace is generated and the standard panic
functionallity of RIOT is sidestepped.
Use `core_panic` instead.

In `timer_init`, `freq` is being check so its not unused.
In `timer_set_periodic`, `flags` is being used too.
Remove the uses of `(void)` in both cases.

Initial version to test 64 bit compatibility.
Instead of a separate board, the inital version for Linux/x86_64 is enabled
by setting the environment variable `NATIVE_64BIT=y` and compiling as usual.
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
This provides glibc, NetBSD, FreeBSD compatible endian.h header with a
lean and simple API to convert between host byte order to little endian
and big endian and the other way around.
Add support for querying the frequency supported by
`periph_timer`. This allows applications which require
this feature to run on the `native` board.

The tramp assembly was missing a `.note.GNU-stack` section,
meaning the compiler was forced to assume that we require
an executable stack.
Fix this by adding the necessary section.

Note that for the very CPU this driver is used with (nRF52 on the
microbit-v2 board), this currently needs extra workarounds to copy
written data from flash to RAM so that the driver can see it. (Otherwise
it silently writes 00, and then correctly reads 00 from the bus all the
time).
The underlying peripheral can only read from RAM. This uses the
existing infrastructure (already needed to work around the lack of a
hardware support for I2C_NOSTART) to unconditionally copy any to-be-sent
data into RAM.
