* Linux: implement signal stacktrace using SA_SIGINFO + sigaltstack
Adds proper signal handlers for SIGSEGV/SIGBUS/SIGILL on Linux,
enables backtraces from signal context, and exits with correct POSIX
signal codes (128+signal). Fixes missing "signal stacktrace" support

* Add NetBSD Support
Includes:
- Hints to find non-compatibility libc functions
- Struct and constant definitions for sockets, polling, etc.
- Changes to the linker code to work around some quirks in the NetBSD dynamic linker
- A target triple for netbsd aarch64 so llvm builds/links the compiler properly on this platform
* Updated releasenotes and some compacting

* add join for ThreadPool without destroying the threads
* Make the main Thread block waiting for the worker threads to finish instead of buzy looping and do proper initialization and freeing of all variables.
* Updated test to use `atomic_store` and take into account the maximum queue size of the threadpool.
* - Add `ThreadPool` join function to wait for all threads to finish in the pool without destroying the threads.
- Return of Thread/Mutex/CondVar `destroy()` is now "@maydiscard" and should be ignored. It will return void in 0.8.0.
- Return of Mutex `unlock()` and `lock()` is now "@maydiscard" and should be ignored. They will return void in 0.8.0.
- Return of ConditionVariable `signal()` `broadcast()` and `wait()` are now "@maydiscard". They will return void in 0.8.0.
- Return of Thread `detatch()` is now "@maydiscard". It will return void in 0.8.0.
- Buffered/UnbufferedChannel, and both ThreadPools have `@maydiscard` on a set of functions. They will retunr void in 0.8.0.
- Pthread bindings correctly return Errno instead of CInt.
- Return of Thread `join()` is now "@maydiscard".
