* The ucontext API is no longer the API, introduce "nuitka/fibers.hpp" with what Nuitka needs. * Remove usage of Win32 library for ucontext, no more needed, the new API is easy to cover. * For x64 the swapFiber is our own assembler code, inspired by libc, but it doesn't do the useless syscall to set process signal mask. Otherwise the libc ucontext implementation is used. This gives a 8x speedup for the test case. * Port ARM to new API as well. * Provide a fallback for x86 and everything else that uses ucontext API for where it is available and working. * Added small program to verify how long it takes to context switch on a platform. * For a small exta boost (0.5% in test case), cache the last used stack and reuse it if possible. * Added a missing unlikely indicator to generator creation. It is not going to fail normally.
