* priority_queue_t: Replaced `-1U` literal with PRIORITY_QUEUE_DATA_SIGNALING define
* architecture.h: Added 64-bit
* bloom.h: Fixed typedef for the hashfp_t function pointer
* vfs.h: Increased default vfs buffer sizes for 64 bit
* bytes.h: Check if socklen_t is already defined
* ztimer: Use PRIxPTR format specifier
On ARM platforms, `__dso_handle` is used for dynamic shared objects. But it is also required if global static objects are used. To avoid that `sys/cpp11_compat` is required only for using the (re)defined `new`/`delete` operators, `__dso_handle` is moved to module `sys/cpp_new_delete`
The `new` and `delete` operators that don't need `libtsdc++` are also provided by module `sys/cpp_new_delete` for platforms that don't have the `libstdc++`. Since these operators in `sys/cpp11-compat` are just wrappers for standard `malloc`/`free` functions like in `sys/cpp_new_delete`, the `new`/`delete` operators that don't need `libstdc++` are used from `sys/cpp_new_delete`. Only the `new`/`delete` operators that require the `libstd++` are left in `sys/cpp11-compat`.
So it is sufficient for the use of the (re)defined `new`/`delete` operators that an application uses the module `sys/cpp_new_delete` instead of `sys/cpp11-compat` and thus also works on platforms without `libstdc++`.
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
- Introduced enum type `thread_state_t` to replace preprocessor macros
- Moved thread states to `sched.h` for two reasons:
a) Because of the interdependencies of `sched.h` and `thread.h` keeping it in
`thread.h` would result in ugly code.
b) Theses thread states are defined from the schedulers point of view, so it
actually makes senses to have it defined there

cppsupport.cpp contains functions which are necessary in order to use
some features of the C++ language, e.g. calling static constructors or
virtual functions.
TODO/Not implemented yet:
- Test virtual functions
- Handle exceptions (stack unwinding)
- Run time type identification (RTTI)
As discussed in #2725, this commit renames a number of stacksize constants to
better convey their intended usage. In addition, constants for thread priority
are given a `THREAD_` prefix. Changes are:
* KERNEL_CONF_STACKSIZE_PRINTF renamed to THREAD_EXTRA_STACKSIZE_PRINTF
* KERNEL_CONF_STACKSIZE_DEFAULT renamed to THREAD_STACKSIZE_DEFAULT
* KERNEL_CONF_STACKSIZE_IDLE renamed to THREAD_STACKSIZE_IDLE
* KERNEL_CONF_STACKSIZE_MAIN renamed to THREAD_STACKSIZE_MAIN
* Move thread stacksizes from kernel.h to thread.h, since the prefix changed
* PRIORITY_MIN renamed to THREAD_PRIORITY_MIN
* PRIORITY_IDLE renamed to THREAD_PRIORITY_IDLE
* PRIORITY_MAIN renamed to THREAD_PRIORITY_MAIN
* Move thread priorities from kernel.h to thread.h since the prefix has changed
* MINIMUM_STACK_SIZE renamed to THREAD_STACKSIZE_MINIMUM for consistency
These headers do not provide full stl functionality,
but a small subset:
* thread and this_thread
* condition_variable (some timed functions are missing)
* mutex, lock_guard and unique_lock
