Replace direct accesses to sched_active_thread and sched_active_pid with
the helper functions thread_getpid() and thread_get_active(). This serves
two purposes:
1. It makes accidental writes to those variable from outside core less likely.
2. Casting off the volatile qualifier is now well contained to those two
functions
On receiving a DIO message, RPL sets the lifetime for the default
route and the parent timeout event to the value. This leads to short
amounts of time whem the node looses its default route, while it
handles the parent timeout event to probe its parent.
This commit fixes this by adding time the node needs for probing
to the default route lifetime.
In most places, picolibc and newlib are the same, so use
the existing newlib code when compiling with picolibc.

Support for picolibc as alternative libc implementation is added with
this commit. For now only cortex-m CPU's are supported.

squash fixes in
v3:
Remove picolibc integer printf/scanf stuff from sys/Makefile.include,
it gets set in makefiles/libc/picolibc.mk
fixup for dependency
picolibc: Use thread_getpid for getpid() in picolibc_syscalls_default
Instead of directly accessing the sched_active_pid variable (which
isn't defined in this context), use the existing wrapper function
to get that value.

v2:
Squash a couple of fixes in
* fixup! picolibc: Use thread_getpid for getpid() in
picolibc_syscalls_default
* squashme: Add `times` to picolibc syscalls
* Add __noreturn__ attribute to _exit
* Add VFS syscall wrappers. This provides the POSIX api used
by picolibc stdio
When `xtimer_on_ztimer` is used, `xtimer` does not need to perform any clock
conversion. Especially undefined macros of `XTIMER_HZ` and `XTIMER_SHIFT` should
no longer result in compilation issues, as they are not used internally anyway.
`ztimer_init_extend()` should only be defined when module `ztimer_extend` is
used, as otherwise the `struct` member `clock->max_value` is not available.
Add functions to generate an EUI based on the netdev ID.
This will always return the same EUI for the same netdev, so it is
stable across netdev resets.
These functions are independent from GNRC and can be used by stack-agnistoc
code.
Avoid pulling in a GNRC dependency by moving those two helper functions to
`netif`.
The old function names are kept as `static inline` wrapper functions to avoid
breaking API users.
