This drops special handling for Mac OS (X) `native`, which is not
supported anymore anyway and causing issues when building for
non-`native` targets on Mac OS.
- most were trivial
- missing group close or open
- extra space
- no doxygen comment
- name commad might open an implicit group
this hould also be implicit cosed but does not happen somtimes
- crazy: internal declared groups have to be closed internal
When using a toolchain with built-in POSIX thread support, static C++ constructors use a static mutex variable which is initialized with `pthread_once` when first used. However, since RIOT's `pthread_once_t` type is different from that in newlib's `pthread`, which is assumed by GCC, RIOT crashes as soon as static constructors are used.
Changing the `pthread_once_t` type to be compatible with newlib's `pthread_once_t` type solves the problem and allows the RIOT `pthread` modules to be used even with toolchains with built-in POSIX thread support.
Align the first member of `struct sockaddr` and
`struct sockaddr_storage` as `uint32_t` to elevate the alignment of the
structure to level of `uint32_t`. This is needed as
`struct sockaddr_in` uses an `uint32_t` to store the IPv4 address,
previously resulting in `struct sockaddr_in` currently having a greater
alignment requirement that `struct sockaddr_storage`.
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
In most places, picolibc and newlib are the same, so use
the existing newlib code when compiling with picolibc.

This enables 'pthread' support on arduino.
avr-libc C90 'time.h' does not include 'sys/types.h' as POSIX expects it.
However, the type previously defined conflicts with the one in
'cpu/atmega_common/avr_libc_extra/include/sys/types.h' when both are
included, so include 'sys/types.h'.
Maybe it should alway be included by 'time.h' but this
would need its specific review.
