hurd: Add getcontext, makecontext, setcontext, swapcontext
Adapted from the Linux x86 functions. Not thoroughly tested, but manual testing as well as glibc tests look fine, and manual -lpthread testing also looks fine (within the given bounds for a new stack to be used with makecontext). This has also been in use in Debian since 2013.
